INTRODUCTION »  
We would like to congratulate you on your purchase of a KTM motorcycle.  
You are now the owner of a state-of-the-art sports motorcycle that guarantees to bring you lots of fun and  
enjoyment, provided that you clean and maintain it appropriately. Before you go for your first ride, be sure  
to read this manual carefully and thoroughly in order to familiarize yourself with how to operate your new  
motorcycle and with its characteristics, even if this means that you will have to dedicate some of your  
valuable time to this task. Only by doing so will you learn how to tune your motorbike to your specific  
needs and how to protect yourself against injury. Besides, this manual contains important information on  
motorcycle maintenance. At the time this manual was typeset, it was up-to-date with the latest state of  
this production series. It cannot be completely ruled out, however, that minor discrepancies may exist  
resulting from further design upgrades of these motorcycles.This manual is an important part of your motor-  
bike and should be passed on to any subsequent owner in case you decide to sell it.  
We expressly point out that work marked with an asterisk in the chapter "Maintenance work on the chas-  
sis and engine" must be performed by a KTM workshop. If maintenance work should become necessary  
during a competition, it must be performed by a trained mechanic.  
For your own safety, use KTM-approved parts and accessories only. KTM is not liable for damage that  
arises in connection with the use of other products.  
2
Take special care to follow the recommended run in, inspection, and maintenance intervals. Heeding  
these guidelines will significantly increase the life of your motorcycle. Have services carried out by a KTM  
dealer so that your warranty claim remains intact.  
Off-road motorcycle driving is a wonderful sport and we hope that you will be able to enjoy it to the full.  
It may, however, involve potential problems for the environment or lead to conflicts with others. These  
problems or conflicts can be avoided if the motorcycle is used responsibly. To safeguard the future of  
motorcycle sports, make sure that you use the motorcycle in accordance with the law, show that you are  
environmentally conscious and respect the rights of others.  
We wish you a lot of fun when driving !

IMPORTANT WARRANTY AND GUARANTEE INFORMATION »  
KTM sports motorcycles are designed and constructed to resist the usual wear and tear of normal use in  
competitions.  
The motorcycles comply with the regulations and categories currently in effect with the leading interna-  
tional motorcycle associations.  
Observance of the service, maintenance and tuning instructions for the engine and chassis specified in  
the Owner's Manual is a prerequisite for faultless operation and the avoidance of premature wear. An  
improperly tuned chassis can lead to damage and breakage of the chassis components (see chapter on  
checking the basic chassis setting).  
The service work specified in the "Lubrication and Maintenance Schedule" must be performed by a KTM  
workshop and recorded in the service manual otherwise claims under the warranty shall become void.  
The fuels and lubricants specified in the Owner's Manual or automotive fluids with equivalent specifica-  
tions must be used in accordance with the maintenance schedule.  
No claims can be filed under the warranty for damage or consequential damage caused by manipulations  
or conversions to the motorcycle.  
3
The use of the motorcycle under extreme conditions, e.g. on extremely muddy and wet terrain, can lead  
to higher than average wear on components such as the drive train or the brakes. In this case it may  
become necessary to service or replace wear parts before the service limit specified in the maintenance  
schedule has been reached.  
THE SX/SXS AND XC MODELS ARE PROHIBITED ON PUBLIC ROADS.  
The EXC models are only allowed on public roads in the original homologated (throttled) version. Without  
this performance restriction (i.e. dethrottled), these models are only allowed to be driven off-road but not  
on public roads. The EXC models are designed for off-road sports endurance competitions(enduro) and  
not suitable for predominant motocross use.  
2-STROKE OFFROAD MOTORCYCLES ON PUBLIC ROADS  
KTM EXC and XC-W models were designed for offroad use only and are only suitable for longer rides on  
public roads to a certain extent. The engine is subjected to completely different performance demands  
on public roads and must be adapted to these operating conditions.  
Ask your KTM dealer for more information.  
In accordance with the international quality management ISO 9001 standard, KTM uses  
quality assurance processes that lead to the highest possible product quality.

Damping action during compression of shock absorber (SX)  
The shock absorber on the SX models can synchronize the compression  
damping in the low and high-speed range separately (Dual Compression  
Control).  
Low and high speed refers to the movement of the shock absorber during com-  
pression and not to the speed of the motorcycle.  
The low and high-speed technology overlaps.  
The low-speed setting is primarily for slow to normal shock absorber  
compression rates.The high-speed setting is effective at fast compression  
rates.Turning in a clockwise direction will increase the damping, turning coun-  
terclockwise will decrease the damping.  
STANDARD LOW-SPEED SETTING:  
– Turn the adjusting screw [4] to the limit in a clockwise direction using a  
screwdriver .

GENERAL TIPS AND WARNINGS FOR STARTING THE MOTORCYCLE »  
Instructions for your first ride  
– Make sure the work for the "pre-delivery inspection" was per-  
– WEAR SUITABLE CLOTHING WHEN DRIVING A MOTORCYCLE. SMART  
formed by your authorized KTM workshop. The DELIVERY CER-  
KTM DRIVERS ALWAYS WEAR A HELMET, BOOTS, GLOVES, AND A  
TIFICATE and SERVICE MANUAL will be handed over when you  
JACKET, REGARDLESS OF WHETHER DRIVING ALL DAY OR JUST  
pick up your vehicle.  
GO FOR A SHORT RIDE. THE PROTECTIVE CLOTHING SHOULD BE  
BRIGHTLY COLORED SO THAT OTHER USERS OF THE ROADS CAN  
SEE YOU AS EARLY AS POSSIBLE. OF COURSE YOUR PASSENGER  
WILL ALSO NEED SUITABLE PROTECTIVE CLOTHING.  
– Thoroughly read the whole instruction manual before  
starting for your first tour.  
– Familiarize yourself with the controls.  
– Adjust the clutch lever, the hand brake lever and the foot brake  
pedal to the most comfortable position.  
– Get used to handling the motorcycle on an empty parking lot  
or open space, before going for a longer ride. Also try to ride  
as slowly as possible while standing upright, to improve your  
feeling for the vehicle.  
– Do not drive along off-road trails which go beyond your ability  
and experience.  
– Hold the handlebar with both hands and leave your feet on the  
foot rests while driving.  
– Remove your foot from the foot brake lever when you are not  
braking. If the foot brake lever is not released the brake pads  
rub continuously and the braking system is overheated.  
– You may only take a passenger along if your motorcycle is fit-  
ted and registered for such purposes. During the ride, the pas-  
senger must hold on to the straps or to the driver, with his feet  
on the passenger footrests.  
– Do not make any alterations to the motorcycle and always use  
ORIGINAL KTM SPARE PARTS. Spare parts from other man-  
ufacturers can impair the safety of the motorcycle.  
– Motorcycles are sensitive to alterations in the distribution of  
weight. If you are taking luggage with you, it should be secured  
as close as possible to the middle of the vehicle; distribute the  
weight evenly between the front and the rear wheel. Never  
exceed the maximum permissible laden weight and the axle  
weights. The maximum permissible laden weight is made up  
of the following components:  
– ALWAYS TURN ON THE LIGHT TO MAKE SURE THAT OTHER DRIV-  
ERS BECOME AWARE OF YOU AS EARLY AS POSSIBLE.  
– DO NOT DRIVE AFTER HAVING CONSUMED ALCOHOL.  
– ONLY USE ACCESSORY PARTS RECOMMENDED BY KTM. FOR EXAM-  
PLE, FRONT PANELLING CAN IMPAIR THE DRIVING CHARACTER-  
ISTICS OF THE MOTORCYCLE. CASES, EXTRA TANKS ETC. CAN  
ALTER THE WEIGHT DISTRIBUTION AND THUS ALSO IMPAIR THE  
VEHICLE’S DRIVING  
CHARACTERISTICS.  
– THE FRONT AND REAR WHEEL ARE ALLOWED TO BE FITTED ONLY  
WITH TIRES THAT HAVE THE SAME PROFILE TYPE.  
– BE SURE TO CHECK THE SPOKE TENSION AFTER 30 MINUTES' RUN-  
NING TIME. THE SPOKE TENSION WILL DECREASE QUICKLY ON  
NEW WHEELS. IF YOU CONTINUE TO DRIVE WITH LOOSE SPOKES,  
THE SPOKES MAY CRACK AND LEAD TO UNSTABLE HANDLING (SEE  
"CHECKING THE SPOKE TENSION").  
– OBSERVE THE TRAFFIC REGULATIONS, DRIVE DEFENSIVELY AND  
TRY TO LOOK AHEAD AS FAR AS POSSIBLE SO THAT YOU RECOG-  
NIZE ANY HAZARDS AS EARLY AS POSSIBLE.  
– ADJUST YOUR DRIVING SPEED TO THE CONDITIONS AND YOUR  
DRIVING SKILLS.  
– DRIVE CAREFULLY ON UNKNOWN ROADS OR IN UNKNOWN  
TERRITORY.  
– WHEN DRIVING OFF-ROAD, ALWAYS HAVE A FRIEND ON A SECOND  
MOTORCYCLE TO KEEP YOU COMPANY, SO THAT YOU CAN HELP  
EACH OTHER SHOULD DIFFICULTIES ARISE.  
– REPLACE THE HELMET VISOR OR GOGGLE GLASSES EARLY ENOUGH.  
WHEN LIGHT SHINES DIRECTLY ON A SCRATCHED VISOR OR GOG-  
GLES, YOU WILL BE PRACTICALLY BLIND.  
– NEVER LEAVE YOUR MOTORCYCLE WITHOUT SUPERVISION AS  
LONG AS THE ENGINE IS RUNNING.

– WHEN RIDING YOUR MOTORCYCLE, PLEASE BEAR IN MIND THAT  
OTHER PEOPLE MAY FEEL MOLESTED BY EXCESSIVE NOISE.  
Running in  
Even very precisely machined sections of engine components have  
rougher surfaces than components which have been sliding across  
one another for quite some time. Therefore, every engine needs to  
be broken in. For this reason, during its first 500 kilometers (300  
miles) or 5 hours the engine must not be revved up to its perform-  
ance limits.  
Apply low but changing loads for running-in.  
DO NOT DRIVE AT FULL LOAD FOR THE FIRST 500 KILOMETERS (300  
MILES) OR 5 HOURS!

DRIVING INSTRUCTIONS »  
What you should check before each start  
When you start off, the motorcycle must be in a perfect technical condition.  
For safety reasons, you should make it a habit to perform an overall check of  
your motorcycle before each start.  
The following checks should be performed:  
1
2
3
CHECK TRANSMISSION OIL LEVEL  
Too little transmission oil leads to premature wear and will ultimately destroy  
gear wheels and parts of the shift mechanism.  
FUEL  
Check that there is sufficient fuel in the tank; when closing the filler cap,  
check that the tank venting hose is free of kinks.  
CHAIN  
A loose chain was fall off the chain wheels; an extremely worn chain may  
tear, and insufficient lubrication may result in unnecessary wear of the  
chain and chain wheels.  
4
5
TIRES  
Check for damaged tires. Tires showing cuts or dents must be replaced.  
The tread depth must comply with the legal regulations. Also check the  
air pressure. Insufficient tread and incorrect air pressure deteriorate the  
driving performance.  
BRAKES  
Check correct functioning of the braking system. Verify that there is suf-  
ficient brake fluid in the reservoir. The reservoirs have been designed in  
such a way that brake fluid does not need to be refilled even when the  
brake pads are worn. If the level of brake fluid falls below the minimum  
value, this indicates a leak in the braking system or completely worn out  
17  
brake pads. Arrange for the braking system to be checked by an  
author-  
ized KTM dealer, as complete failure of the braking system can be expected.  
Also check the state of the brake hose and the thickness of the brake  
linings.  
Check free travel of the hand brake lever and foot brake lever.  
IF THE RESISTANCE IN THE HAND BRAKE LEVER OR FOOT BRAKE PEDAL FEELS  
„SPONGY“ (TOO MUCH GIVE), THIS IS AN INDICATION THAT SOMETHING IS WRONG  
WITH THE BRAKE SYSTEM. DON’T RIDE YOUR MOTORCYCLE ANYMORE WITHOUT  
FIRST HAVING THE BRAKE SYSTEM LOOKED OVER BY A KTM DEALER.  
6
7
8
CABLES  
Check correct adjustment and easy running of all control cables.  
COOLING FLUID  
Check the level of cooling fluid when the engine is cold.  
ELECTRICAL SYSTEM  
Check correct functioning of headlamps, tail-lights, brake lights, turn  
indicators, indicator lamps and horn while the engine is running.  
9
LUGGAGE  
If you are taking luggage with you, check that it is securely fastened.

Open fuel tap  
Turn on ignition or emergency OFF switch  
Swing up the side stand  
Put the gear in neutral  
Activate cold-starting aid (choke)  
Leave throttle closed or open it no more than 1/3 and kick down kick-  
starter vigorously all the way.  
– FOR STARTING ALWAYS PUT ON YOUR MOTORCYCLE BOOTS TO AVOID INJURIES.  
YOU COULD SLIP OFF THE KICKSTARTER OR THE MOTOR COULD KICK BACK  
AND FLING YOUR FOOT UPWARDS.  
– FORCEFULLY KICK THE KICKSTARTER DOWN THE WHOLE WAY AND DO NOT  
OPEN THE THROTTLE. A KICKSTART WITH TOO LITTLE MOMENTUM AND AN  
OPENED THROTTLE INCREASES THE KICKING BACK RISK.  
– CHECK FOR POWER TRANSMISSION AT TEMPERATURES BELOW 0°C (32°F)  
BEFORE YOU ACTUATE THE KICKSTARTER. IF YOU DEPRESS THE KICKSTARTER  
WITHOUT FEELING ANY RESISTANCE, POWER IS NOT BEING TRANSMITTED.  
THIS COULD CAUSE INJURIES.  
– DO NOT START THE ENGINE AND ALLOW IT TO IDLE IN A CLOSED AREA.  
EXHAUST FUMES ARE POISONOUS AND CAN CAUSE LOSS OF CONSCIOUS-  
NESS AND DEATH. ALWAYS PROVIDE ADEQUATE VENTILATION WHILE THE  
ENGINE IS RUNNING.  
DO NOT RIDE YOUR MOTORCYCLE WITH FULL LOAD AND DO NOT REV UP THE  
ENGINE WHEN COLD. SINCE THE PISTON WARMS UP AND EXPANDS FASTER THAN  
THE WATER COOLED CYLINDER, THIS MIGHT CAUSE ENGINE DAMAGE. ALWAYS  
LET ENGINE IDLE UNTIL WARM OR DRIVE IT WARM AT LOW R.P.M. SPEEDS.  
18  
NOTE:  
The highly inflammable components in modern fuels volatilize if left stand-  
ing for longer periods of time. If the motorcycle has not been used for over  
1 week, the fuel should be drained from the float chamber. The engine will  
start up immediately if the float chamber is filled with fresh, ignitable fuel

Start engine with full throttle. If necessary, unscrew spark plug and dry it.  
Once the engine is running, open fuel tap again.  
Starting off  
Pull the clutch lever. Put the engine into first gear, slowly release the clutch  
lever and accelerate at the same time.  
– BEFORE YOU START OFF, CHECK THAT THE MAIN OR SIDE STAND HAS BEEN  
SWUNG RIGHT UP TO THE TOP. IF THE STAND DRAGS ON THE FLOOR, YOU  
MAY LOSE CONTROL OF YOUR MOTORCYCLE.  
– BEFORE STARTING FOR AN OFF-ROAD TOUR, IT IS RECOMMENDED TO ADDI-  
TIONALLY SECURE THE SIDE STAND WITH THE RUBBER BAND ON THE AIR  
FILTER BOX.  
Shifting/Riding  
You are now in first gear, referred to as the drive or uphill gear. Depending on  
the conditions (traffic, hill size, etc.), you can shift to a higher gear. Turn down  
the throttle, at the same time pull the clutch lever in and shift to the next  
higher gear. Let the clutch lever go again and open the throttle. If you turned  
on the choke, make sure you turn it off again as soon as engine is warm.  
When you reach full speed through opening the throttle all the way, turn throt-  
tle back to 3/4; the speed hardly decreases although the engine will use less  
gas. Only give as much gas as the engine can handle. Through quick and high  
revving of throttle, the gas consumption will increase. When shifting down,  
use the brakes if necessary and turn down at the same time. Pull the clutch  
lever and shift down to the next lower gear. Let the clutch lever go slowly and  
open the throttle or shift down again.

DRIVING INSTRUCTIONS »  
– THE SIDE STAND IS ONLY DESIGNED FOR THE WEIGHT OF THE  
MOTORCYCLE. IF YOU GET ON YOUR MOTORCYCLE AND THUS PUT  
ADDITIONAL WEIGHT ON THE MOTORCYCLE, THE SIDE STAND OR  
THE FRAME CAN BE DAMAGED OR THE MOTORCYCLE MAY FALL  
ON THE SIDE.  
– AFTER FALLING WITH THE MOTORCYCLE, CHECK ALL ITS FUNC-  
TIONS THOROUGHLY BEFORE USING IT AGAIN.  
– A TWISTED HANDLEBAR MUST ALWAYS BE REPLACED. DO NOT  
ADJUST THE HANDLEBAR, IT WILL LOSE STABILITY.  
Refueling, fuel  
125-300: Unleaded premium gasoline RON 95 mixed with high  
– HIGH RPM RATES WHEN THE ENGINE IS COLD HAVE AN ADVERSE  
EFFECT ON THE LIFE OF YOUR ENGINE. WE RECOMMEND YOU RUN grade two stroke oil. Mixture ratio 1:40 - 1:60  
THE ENGINE IN A MODERATE RPM RANGE FOR A FEW MILES GIV-  
ING IT A CHANCE TO WARM UP. AFTER THAT NO FURTHER PRE-  
CAUTIONS IN THIS RESPECT NEED TO BE TAKEN.  
Fuel and engine oil should only be mixed immediately before use.  
KTM recommends Motorex Cross Power 2T.  
– NEVER HAVE THE THROTTLE WIDE OPEN WHEN CHANGING DOWN  
TO A LOWER GEAR. THE ENGINE WILL OVERREV, DAMAGING THE  
VALVES. IN ADDITION, THE REAR WHEEL WILL BLOCK SO THAT THE  
MOTORCYCLE CAN EASILY GET OUT OF CONTROL.  
– IF THE ENGINE RUNS WITHOUT THROTTLE DURING LONGER  
DOWNHILL TRAVEL, THE ENGINE SHOULD BE ACCELERATED OCCA-  
SIONALLY TO ENSURE THAT IT IS SUPPLIED WITH SUFFICIENT  
LUBRICANT WHICH IS MIXED IN THE FUEL.  
– IN THE EVENT THAT, WHILE RIDING ON YOUR MOTORCYCLE, YOU  
NOTICE ANY UNUSUAL OPERATION-RELATED NOISE, STOP IMME-  
DIATELY, TURN THE ENGINE OFF, AND CONTACT AN AUTHORIZED  
KTM DEALER.  
GASOLINE IS HIGHLY FLAMMABLE AND POISONOUS. EXTREME CAU-  
TION SHOULD BE USED WHEN HANDLING GASOLINE. DO NOT REFUEL  
THE MOTORCYCLE NEAR OPEN FLAMES OR BURNING CIGARETTES.  
ALWAYS SWITCH OFF THE ENGINE BEFORE REFUELING. BE CAREFUL  
NOT TO SPILL GASOLINE ON THE ENGINE OR EXHAUST PIPE WHILE  
THE ENGINE IS HOT. WIPE UP SPILLS PROMPTLY. IF GASOLINE IS SWAL-  
LOWED OR SPLASHED IN THE EYES, SEEK A DOCTOR’S ADVICE  
IMMEDIATELY.  
– ONLY USE PREMIUM-GRADE GASOLINE ROZ 98 RESPECTIVELY 95  
MIXED WITH HIGH-GRADE TWO-STROKE ENGINE OIL. OTHER TYPES  
OF GASOLINE CAN CAUSE ENGINE FAILURE.  
– DO NOT USE PREMIXED TWO-STROKE OILS, OILS FOR OUTBOARD  
ENGINES OR NORMAL ENGINE OIL TO PREPARE THE MIXTURE.  
– DO NOT USE GASOLINE AND OIL MIXTURES THAT ARE OLDER  
THAN ONE WEEK. THE LUBRICATION PROPERTIES OF SOME TWO-  
STROKE OILS CAN DETERIORATE VERY RAPIDLY.  
Braking  
Turn off the gas and apply the hand and foot brakes at the same  
time. When driving on sandy, wet or slippery ground, use mainly  
the rear wheel brake. Always brake with feeling, blocking wheels  
can cause you to skid or fall. Also change down to lower gears depend-  
ing on your speed.  
19  
– ONLY USE KNOWN BRANDS OF HIGH-GRADE 2-STROKE ENGINE  
OIL (I.E. MOTOREX CROSS POWER 2T).  
– NEVER MIX SYNTHETIC OILS AND MINERAL OILS.  
– NOT ENOUGH OIL OR LOW-GRADE OIL CAN CAUSE EROSION OF  
THE PISTON. WHEN USING TOO MUCH OIL, THE ENGINE MAY  
START SMOKING AND FOUL THE SPARK PLUG.  
– IF YOUR MOTORCYCLE IS EQUIPPED WITH A CATALYTIC CON-  
VERTER, ALWAYS KEEP IN MIND THAT LEADED FUEL WILL DESTROY  
THE CATALYTIC CONVERTER.  
– IN CASE OF RAIN, AFTER WASHING THE MOTORCYCLE, AFTER  
RIDES THROUGH WATER AND IN CASE OF RIDES ON WET OFF-ROAD  
TRACKS, HUMID OR DIRTY BRAKE DISCS CAN DELAY THE BRAK-  
ING EFFECT. THE BRAKES MUST BE PULLED UNTIL THEY ARE DRY  
OR CLEAN.  
– RIDES ON SALT-STREWED OR DIRTY ROADS CAN ALSO DELAY THE  
BRAKING EFFECT. THE BRAKES MUST BE PULLED UNTIL THEY ARE  
CLEAN.  
– FUEL EXPANDS WHEN ITS TEMPERATURE RISES. THEREFORE DO  
NOT FILL THE TANK TO THE TOP. (SEE FIG.)  
– DIRTY BRAKE DISCS CAUSE INCREASED TEAR OF BRAKE PADS AND  
BRAKE DISCS.  
– WHEN YOU BRAKE, THE BRAKE DISCS, BRAKE PADS, BRAKE  
CALIPER AND BRAKE FLUID HEAT UP. THE HOTTER THESE PARTS  
GET, THE WEAKER THE BREAKING EFFECT. IN EXTREME CASES,  
THE ENTIRE BRAKING SYSTEM CAN FAIL.  
– IF THE RESISTANCE IN THE HAND BRAKE LEVER OR FOOT BRAKE  
PEDAL FEELS “SPONGY” (TOO MUCH GIVE), THIS IS AN INDICA-  
TION THAT SOMETHING IS WRONG WITH THE BRAKE SYSTEM. DON’T  
RIDE YOUR MOTORCYCLE ANYMORE WITHOUT FIRST HAVING THE  
BRAKE SYSTEM LOOKED OVER BY A KTM DEALER.  
35 mm  
Stopping and parking  
Close the throttle and apply the hand and foot brake simultane-  
ously. Be especially careful when you apply the brakes on sandy,  
wet or slick surfaces. Always apply the brakes intuitively, locked  
wheels can cause the bike to skid or crash. Shift down to a lower  
gear to match your speed. Always apply the brakes before you enter  
a curve.  
MOTORCYCLE ENGINES PRODUCE A GREAT AMOUNT OF HEAT WHILE  
RUNNING. THE ENGINE, EXHAUST PIPE, MUFFLER, BRAKE ROTORS,  
AND SHOCK ABSORBERS CAN BECOME VERY HOT. DO NOT TOUCH ANY  
OF THESE PARTS AFTER STARTING THE MOTORCYCLE, AND TAKE  
CARE TO PARK IT WHERE PEDESTRIANS ARE NOT LIKELY TO TOUCH  
IT AND GET BURNED.  
– CLOSE THE FUEL TAP WHEN LEAVING YOUR VEHICLE. OTHERWISE  
THE CARBURETOR MAY GET FLOODED AND FUEL WILL ENTER  
THE ENGINE.  
– NEVER PARK YOUR MOTORCYCLE IN PLACES WHERE THERE EXIST  
FIRE HAZARDS DUE TO DRY GRASS OR OTHER EASILY FLAMMA-  
BLE MATERIALS.

MAINTENANCE WORK ON CHASSIS AND ENGINE »  
MAINTENANCE AND ADJUSTING WORK MARKED WITH AN ASTERISK * REQUIRES EXPERT SKILLS AND TECHNICAL KNOW-HOW. FOR YOUR  
OWN SAFETY, ALWAYS HAVE SUCH WORK PERFORMED BY A SPECIALIZED KTM DEALER WHERE YOUR MOTORCYCLE WILL BE OPTIMALLY SERV-  
ICED BY APPROPRIATELY QUALIFIED, SKILLED STAFF.  
– IF USING A POWER WASHER, DO NOT POINT THE WATER JET AT THE ELECTRIC COMPONENTS, PLUGS, CABLES, BEARINGS, CARBURE-  
TOR, ETC. THE HIGH PRESSURE WILL CAUSE WATER TO PENETRATE INTO THE COMPONENTS AND CAN CAUSE THEM TO MALFUNCTION  
OR LEAD TO PREMATURE WEAR.  
– WHEN TRANSPORTING YOUR KTM, ENSURE THAT IT IS HELD UPRIGHT WITH RESTRAINING STRAPS OR OTHER MECHANICAL FASTENING  
DEVICES AND THAT THE FUEL TAP IS IN THE OFF POSITION - IF THE MOTORCYCLE SHOULD FALL OVER, NO FUEL CAN LEAK FROM THE  
CARBURETOR OR FUEL TANK  
– ONLY USE SPECIAL SCREWS WITH AN APPROPRIATE THREAD LENGTH SUPPLIED BY KTM TO FIX THE SPOILERS ON THE TANK. USING  
OTHER SCREWS OR LONGER SCREWS CAN CAUSE LEAKS IN THE TANK THROUGH WHICH FUEL CAN FLOW OUT.  
– DO NOT USE TOOTHED WASHERS OR SPRING RINGS WITH THE ENGINE FASTENING SCREWS, AS THESE WORK INTO THE FRAME PARTS  
AND KEEP WORKING LOOSE. INSTEAD, USE SELF-LOCKING NUTS.  
– IF YOU UNSCREWED ANY SCREWED CONNECTIONS WITH SELF-LOCKING NUTS, THEY MUST BE REPLACED WHEN MOUNTING. IF NO SELF-  
LOCKING NUTS ARE AVAILABLE, APPLY LOCTITE 243 TO THE THREAD. THE SCREWS AND NUTS MUST BE REPLACED IF THE THREAD IS  
DAMAGED.  
– ALL SCREWS AND NUTS MUST BE TIGHTENED TO THE SPECIFIED TORQUE FIGURES USING A TORQUE WRENCH. IF SCREWS OR NUTS  
ARE NOT ADEQUATELY TIGHTENED, THEY CAN BECOME LOOSE AND CAUSE THE MOTORCYCLE TO GO OUT OF CONTROL WHILE YOU DRIVE.  
TIGHTENING THE SCREWS AND NUTS TOO TIGHTLY CAN DAMAGE THE THREAD AND COMPONENTS.  
– LET YOUR MOTORCYCLE COOL DOWN BEFORE BEGINNING ANY MAINTENANCE WORK IN ORDER TO AVOID GETTING BURNED.  
– DISPOSE OF OILS, FATTY MATTERS, FILTERS, FUELS, WASHING DETERGENTS, ETC. PROPERLY.  
– UNDER NO CIRCUMSTANCES MAY USED OIL BE DISPOSED OF IN THE SEWAGE SYSTEM OR IN THE OPEN COUNTRYSIDE. 1 LITER OF USED  
OIL CONTAMINATES 1,000,000 LITERS OF WATER.  
24  
Changing the spring preloading of the shock absorber  
The spring preload can be changed by turning the adjusting ring [1]. For this  
purpose, you should dismount the shock absorber and clean it thoroughly.  
NOTE:  
– Before changing the spring preload note down the basic setting, e.g. how  
many threads are visible above the adjusting ring.  
2
– One rotation of the adjusting ring [1] changes the spring pretension by  
approximately 1.75 mm (0.07 in).  
Loosen the clamping screw [2] and use the hook wrench contained in the  
vehicle tool set to turn the adjusting ring as desired. Turning it counterclock-  
wise will reduce the preload, turning it clockwise will increase the preload.  
After readjusting the clamping screw [2], tighten it to 8 Nm (6 ft.lb)

ADJUSTMENT VALUES – SPRING PRELOAD [A]  
STANDARD PRELOAD . . .5 mm (0.20 in)

Pivot bearing  
The pivot bearing [3] for PDS suspension struts at the swinging fork is Teflon-  
coated and must not be lubricated with either grease or other lubricants. Grease  
and other lubricants cause the Teflon coat to dissolve, whereby the bearing’s  
lifecycle will be reduced dramatically.  
When cleaning your bike with a high-pressure cleaner, do not aim the high-  
pressure spray directly at the pivot bearing.

MAINTENANCE WORK ON CHASSIS AND ENGINE »  
Basic suspension setup for the weight of the driver  
To achieve maximum handling performance and to prevent the fork, shock  
absorber, swing arm and frame from being damaged, the basic setup of the  
suspension components must be suitable for your weight. At delivery, KTM's  
offroad motorcycles are set to accommodate a driver weighing 60 - 70 kg (wear-  
ing full protective clothing). If your weight exceeds or falls short of this range,  
you will need to adjust the basic setup for the suspension components accord-  
ingly. Minor deviations in weight can be compensated by adjusting the spring  
preload. Different springs must be installed for larger deviations.  
A
Checking the shock absorber and spring  
You can establish whether or not the shock absorber spring is suitable for your  
weight by checking the riding sag. The static slag must be correctly adjusted  
before the riding sag can be determined.  
Determining the static sag of the shock absorber  
The static sag should be as close as possible to 35 mm. Deviations of more  
than 2 mm can strongly influence the motorcycle's performance.  
Procedure:  
– Jack up the motorcycle until the rear wheel no longer touches the ground.  
– Measure the vertical distance between the rear wheel axle and a fixed point  
(e.g. a mark on the side cover) and write it down as dimension A.  
– Place the motorcycle on the ground again.  
B
25  
– Ask a helper to hold the motorcycle in vertical position.  
– Measure the distance between the rear axle and the fixed point again to  
establish dimension B.  
– The static sag is the difference between dimensions A and B.  
EXAMPLE:  
Motorcycle jacked up (dimension A) . . . . . . . . . . . . . . . . . . . . . .600 mm  
Motorcycle on ground, unloaded (dimension B) . . . . . . . . . . . .– 565 mm  
Static sag . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .35 mm  
If the static sag is lower, the spring preload of the shock absorber must be  
increased, if the static sag is reduced, the spring preload must be higher. See  
chapter "Changing the spring preload of the shock absorber."  
C
Determining the riding sag of the shock absorber  
– Have a helper hold the motorcycle while you sit on the bike in a normal  
seating position (feet on the footrests) wearing full protective clothing and  
bounce up and down a few times to allow the rear wheel suspension to  
become level.  
– Stay on the bike and have another person measure the distance between  
the same two points and write it down as dimension C.  
– The riding sag is the difference between dimensions A and C.  
EXAMPLE:  
Motorcycle jacked up (dimension A) . . . . . . . . . . . . . . . . . . . . . .600 mm  
Motorcycle on ground, loaded (dimension C) . . . . . . . . . . . . . .– 510 mm  
Riding sag . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .90 mm  
for example  
125 SX  
Shock absorber  
The riding sag should lie between 90 and 105 mm.  
If the riding sag is less than 90 mm, the spring is too hard (the spring rate is  
too high). If the riding sag is more than 105 mm, the spring is too soft (the  
spring rate is too low).  
76-250  
The spring rate is written on the outside of the spring (e.g. 72-250). The type  
number of the shock absorber is embossed on the front of the shock absorber.The  
illustrations show which spring should be installed. The standard spring is  
shown in bold print .  
72-250  
69-250

After installing a different spring, readjust the static sag to 35 mm (± 2 mm).

Checking the basic setup of the telescopic fork  
The precise riding sag of the telescopic fork cannot be determined for vari-  
ous reasons. Similar to the shock absorber, smaller deviations in your weight  
can be compensated by adjusting the spring preload. However, if your tele-  
scopic fork bumps frequently (hard end stop during compression), you should  
install harder fork springs to avoid damaging the telescopic fork and frame.  
Changing the spring preload on the telescopic fork (SX models)  
The telescopic forks on the SX models are equipped with a preload adjuster.  
You can easily adjust the spring preload by 10 mm by turning the adjusting  
screw [1].  
Turning in a clockwise direction will increase the prestress, turning in a coun-  
terclockwise direction will decrease the prestress.  
Changing the spring preload will not affect the rebound damping adjustment.  
Generally, if the spring preload is higher, the rebound damping should also  
be set higher.  
1
STANDARD SETTING:  
Unscrew the adjusting screw to the limit and then back 2 turns.  
Changing the spring preload on the telescopic fork  
(XC-W/EXC models)  
The telescopic forks for these models must be partly disassembled to adjust  
the spring preload (see WP manual). Pretension spacers are available in  
heights of 1.5, 2.5 and 5 mm (see spare parts catalog). The fork springs may  
not be pretensioned by more than 20 mm.  
The preload adjuster used in the SX models can easily be retrofitted for the  
telescopic forks of the XC-W/EXC models.  
NOTE:  
WP precisely adjusts the spring pressure by inserting pretension spacers.  
Fluctuations in production are compensated with pretension spacers in vari-  
ous heights. This can cause the fork springs in the fork legs to have different  
degrees of pretension. Fork springs and pretension spacers should always stay  
together.

Replacing fork springs  
If you weigh less than 60 kg or more than 70 kg, you should install the respec-  
tive fork springs. The correct spring rate is shown in the illustrations. The stan-  
dard spring is shown in bold print. The type number of the telescopic fork is  
embossed on the inside of the fork leg axle passage.

Breather plug front fork  
After every 5 hours of use for competitive racing, slacken the breather  
plugs [1] a few turns in order to relieve excess pressure from the inside of the  
fork. To do this, place the motorcycle on a stand with the front wheel lifted  
off the ground. When riding the motorcycle mainly on the road, it will suffice  
to have this job performed in the course of the periodical maintenance  
service.  
EXCESSIVE PRESSURE IN THE INTERIOR OF THE FORK CAN CAUSE LEAKS IN THE  
FORK. IF YOUR FORK IS LEAKING, IT IS RECOMMENDED TO OPEN THE BREATHER  
PLUGS BEFORE HAVING THE SEALS REPLACED.  
1
Cleaning the dust sleeves of the telescopic fork  
The dust-protection bellows [2] are to remove dust and coarse dirt particles  
from the fork tube. However, after some time, dirt may also get in behind the  
dust-protection bellows. If this dirt is not removed, the oil sealing rings located  
behind it may start to leak.  
Use a screwdriver to lift the dust-protection bellows out of the outer tubes  
and slide them downward.  
2
Clean the dust-protection bellows, outer tubes, and fork tubes thoroughly, and  
oil them thoroughly with Universal oil spray (Motorex Joker 440) or engine  
oil. Then, push the dust-protection bellows into the outer tubes by hand.  
NO OIL MAY REACH THE FRONT TIRE OR THE BRAKE DISKS SINCE THIS WOULD  
CONSIDERABLY REDUCE THE TIRE'S ROAD GRIP AND THE BRAKING EFFECT OF  
THE FRONT BRAKE.

Changing the fork offset (caster) (SX / XC) *  
The fork offset [A] in the SX models (center fork legs - center steering head  
angle) can be set to either 18 or 20 mm. This allows you to optimize the han-  
dling to match the race course.  
Remove the blind screw [1] to see which offset is set. If the mark [B] is in  
front, the offset is 18 mm. This setting will deliver more directional stability  
on fast race courses.  
A
If the mark [B] is in the rear as illustrated, the offset is 20 mm. This setting  
will deliver better handling in curves.

leg with a cable tie to keep the brake line from kinking (see illustration).  
Loosen the clamp screws and take the fork legs out of the triple clamps.  
Loosen the collar screw [2] on the lower triple clamp 2 turns.  
Remove the blind screw [1] from the upper triple clamp, loosen the clamp  
screw and upper triple clamp on the seat. Remove the O-ring [3] and the pro-  
tection ring [4].  
Tap gently on the lower triple clamp with a rubber hammer to loosen the steer-

Checking and adjusting the steering head bearing *  
Check steering head bearing for play periodically. To check, put the motorcy-  
cle on a stand so that the front wheel is off the ground. Now try to move the  
fork forward and backward. To adjust the 5 clamping screws [1] and [3], loosen  
the upper triple clamp and turn the end screw [2] until no play is left. Don’t  
tighten the steering stem bolt all the way, otherwise the bearings will be dam-  
aged. With a plastic hammer, lightly tap on the triple clamp to release ten-  
sion. Retighten the five pinch bolts to 15 Nm (SX) / 20 Nm (EXC, XC-W).

How to change the handlebar position  
The handlebar position can be readjusted by 22 mm. Thus, you can put the  
handlebar in the position that is the most convenient for you. The upper triple  
clamp [1] includes 2 bores arranged at a distance of 15 mm (0.6 in) from  
one another. The bores at the handlebar support [2] are offset from the cen-  
ter by 3.5 mm (0.13 in). Accordingly, you can mount the handlebar in  
4 different positions.  
For this purpose, remove screws [3] of the handlebar clamps and screws [4]  
of the handlebar support. Position the handlebar support, and tighten screws  
[4] to 40 Nm (30 ft.lbs). Mount the handlebar and handlebar clamps, and  
tighten screws [3] to 20 Nm (15 ft.lbs). The gap between the handlebar sup-  
port and the handlebar clamps should be the same size in the front and in  
the rear.

Check chain tension  
Jack the motorcycle up on its frame so that the rear wheel no longer touches  
the ground.  
A
Press the chain upward at the end of the chain sliding component. The dis-  
tance between the chain and the swing arm should be approx. 8 - 10 mm  
(0.31 - 0.39 in). In the course of this procedure, the upper chain portion [A]  
must be taut (see drawing). If necessary, correct the chain tension.  
– IF THE CHAIN TENSION IS TOO GREAT, PARTS WITHIN THE SECONDARY TRANS-  
MISSION (CHAIN, CHAIN WHEELS AND REAR WHEEL BEARINGS) WILL BE SUB-  
JECTED TO UNNECESSARY STRESS, RESULTING IN PREMATURE WEAR AND  
EVEN CHAIN BREAKAGE.  
– TOO MUCH SLACK IN THE CHAIN, ON THE OTHER HAND, CAN RESULT IN THE  
CHAIN JUMPING OFF THE CHAIN WHEELS. IF THIS HAPPENS, THE CHAIN COULD  
ALSO BLOCK THE REAR WHEEL OR DAMAGE THE ENGINE.  
– IN EITHER CASE THE OPERATOR IS LIKELY TO LOSE CONTROL OF THE MOTOR-  
CYCLE.

Chain maintenance  
For long chain life, good maintenance is very important. X-ring chains require  
only modest maintenance. The best way is to use lots of water, but never use  
brushes or solvents. After letting the chain dry, you can use a special X-ring  
chain spray (Motorex Chainlube 622).  
NO LUBRICATION IS ALLOWED TO REACH THE REAR TIRE OR THE BRAKE DISK,  
EITHERWISE THE ROAD ADHERENCE AND THE REAR WHEEL BRAKING EFFECTS  
WOULD BE STRONGLY REDUCED AND THE MOTORCYCLE COULD EASILY GET OUT  
OF CONTROL.  
WHEN MOUNTING THE CHAIN JOINT, THE CLOSED SIDE OF THE SAFETY DEVICE  
MUST POINT IN RUNNING DIRECTION.  
Also check sprockets and chain guides for wear, and replace if necessary.

Chain wear  
To check the chain wear, observe the following indications:  
Shift the gear into idling and pull the upper chain strand with approx. 10-15  
kilograms (33 lb) upwards (see figure). Now one can measure a space of 18  
chain reels at the lower chain strand. The chain should be replaced at the lat-  
est when a space of 272 mm (10.70 in) is measured. Chains do not always  
wear off evenly, therefore repeat the measurement at different places on the  
chain.  
NOTE:  
If you mount a new chain, the sprockets should also be replaced. New chains  
wear faster if used on old used sprockets.  
WHEN YOU ASSEMBLE A REAR SPROCKET WITH 14T, THE COLLAR MUST BE ON  
THE INSIDE.  
SECURE THE SCREWS OF THE CHAIN WHEEL BY APPLYING LOCTITE AND FASTEN  
THEM IN A CROSSWISE ORDER.

General information about KTM disc brakes  
BRAKE CALIPERS:  
The brake calipers of this series use a „floating“ mount. This means that the  
brake calipers are not solidly attached to the caliper support, which enables  
them to ”float” for maximum braking contact.Secure the screws of the caliper  
support with Loctite 243 and tighten to 25 Nm (19 ft.lb).  
BRAKE PADS:  
The brake pads are fitted with TOSHIBA TT 2701 sintered lining at the front  
and TOYO B 143 FF sintered lining at the back. These linings provide an opti-  
mal combination of dosing, brake performance and life cycle. The lining type  
is stated on the back of the brake pad and also recorded in the homologation  
papers.  
Other brake pads are available for competition sports.  
FRONT: TOSHIBA H 38 (SINTERED) – harder to dose, good brake perfor-  
mance, long life, for wet slippery terrain.  
FERODO ID 450 (ORGANIC) – easy to dose, good brake perfor-  
mance, short life, for dry terrain, low price.  
REAR: FERODO 4424 (organic) – better controllability, shorter service  
life, for dry terrain.  
TOSHIBA H38 (Sinter) – longer service life than FERODO 4424,  
higher braking performance.  
BRAKE DISCS:  
Due to wear, the thickness of the brake disc in the area of the contact  
face [1] of the brake pads decreases. The brake disk must be at least  
2.50 mm (front) / 3.50 mm (rear) thick at the thinnest point [A]. Check the  
thickness of the brake disk at several points.  
32  
– A BRAKE DISK WORN DOWN TO LESS THAN 2.50 MM (FRONT) / 3.50 MM (REAR)  
IS A SAFETY RISK. HAVE THE BRAKE DISK REPLACED AS SOON AS IT REACHES  
THE SERVICE LIMIT.  
A
– HAVE ANY REPAIRS ON THE BRAKE SYSTEM BE PERFORMED BY A KTM  
DEALER.  
BRAKE FLUID RESERVOIRS:  
The brake fluid reservoirs on the front and rear wheel brakes have been  
designed in such a way that even if the brake pads are worn it is not neces-  
sary to top up the brake fluid. If the brake fluid level drops below the mini-  
mum level either the brake system has a leak or the brake pads are completely  
worn.  
1
In this case, consult an authorized KTM dealer immediately.  
BRAKE FLUID:  
KTM fills the brake systems with Motorex Brake Fluid DOT 5.1 brake fluid,  
one of the best brake fluids is currently available. We recommend that you  
continue to use it. DOT 5.1 brake fluid is based on glycol ether and of an  
amber color. If you do not have any DOT 5.1 for refilling, you may use DOT  
4
brake fluid. However, you should replace it as soon as  
possible with DOT 5.1.  
Never use brake fluid DOT 5. The color of this silicon oil-based product is  
purple red. The gaskets and brake hoses of KTM motorcycles are not  
designed for DOT 5 brake fluid.  
HAVE THE BRAKE FLUID CHANGED AT LEAST ONCE ANNUALLY. IF YOU WASH YOUR  
MOTORCYCLE OFTEN, THE BRAKE FLUID SHOULD BE CHANGED EVEN MORE FRE-  
QUENTLY. BRAKE FLUID TENDS TO ABSORB WATER. THEREFORE, VAPOR POCK-  
ETS MAY FORM IN „OLD“ BRAKE FLUIDS EVEN AT LOW TEMPERATURES, CAUS-  
ING THE BRAKE SYSTEM TO FAIL.

Adjusting the free travel at the hand brake lever  
Free travel at the hand brake lever may be readjusted by using adjustment  
screw [1]. In this way, the position of the point of pressure (i.e. the resis-tance  
you feel on the hand brake lever when the brake pads are pressed against the  
brake disc) can be adjusted for any hand size.  
When you press the hand brake lever forwards, you should have at least  
3 mm free travel. Turn the adjusting screw [1] if necessary.  
min. 3 mm

AT THE HAND BRAKE LEVER, FREE TRAVEL MUST AT LEAST BE 3 MM (0.1 IN).  
ONLY THEN MAY THE PISTON IN THE HAND BRAKE CYLINDER BE MOVED (TO BE  
RECOGNIZED BY THE GREATER RESISTANCE OF THE HAND BRAKE LEVER). IF THIS  
FREE TRAVEL IS NOT PROVIDED, PRESSURE WILL BUILD UP IN THE BRAKING  
SYSTEM, AND THE FRONT-WHEEL BRAKE MAY FAIL DUE TO OVERHEATING.  
Checking the brake fluid level - front brake  
The brake fluid reservoir is linked with the hand brake cylinder at the  
handlebar and the reservoir is provided with an inspection glass. With the reser-  
voir in a horizontal position, the brake fluid level should not drop below the  
middle of the glass.  
IF THE BRAKE FLUID LEVEL DROPS BELOW THE MINIMUM EITHER THE BRAKE  
SYSTEM HAS A LEAK OR THE BRAKE PADS ARE COMPLETELY WORN. IN THIS CASE,  
CONSULT AN AUTHORIZED KTM DEALER IMMEDIATELY.

Tires, air pressure  
Tire type, tire condition, and air pressure level affect the way your motorcy-  
cle rides and must therefore be checked whenever you are getting ready to go  
anywhere on your motorcycle.  
– Tire size can be found in the technical specifications and in the homolo-  
gation certificate  
– Tire condition has to be checked every time you want to ride your motor-  
cycle. Before leaving, check tires for punctures and nails or other sharp  
objects that might have become embedded in them.  
– Refer to the specific regulations in your country for minimum tire tread  
requirements. We recommend you replace the tires at the latest when the  
tread is down to 2 mm (0.08 in).  
– Tire pressure should be checked regularly on a “cold” tire. Proper pres-  
sure ensures optimum driving comfort and extends the life of your tires.

Checking spoke tension  
The correct spoke tension is very important for the stability of the wheels and  
thus for riding safety. A loose spoke causes the wheel to become  
unbalanced and before long other spokes will have come loose. Check spoke  
tension, especially on a new motorcycle, at regular intervals. For checking,  
tap on each spoke with the blade of a screwdriver (see photo). A clear tone  
must be the result. Dull tones are indicators of loose spokes. If necessary,  
have the spokes retightened and the wheel centered by a KTM dealer.  
– SPOKES CAN TEAR IF YOU CONTINUE TO RIDE WITH THEM LOOSE. THIS MAY  
LEAD TO AN UNSTABLE HANDLING OF YOUR MOTORCYCLE.  
– EXCESSIVELY TENSIONED SPOKES MAY RUPTURE DUE TO LOCAL OVERLOAD-  
ING.THE SPOKES MUST BE TENSIONED TO 5 NM.

Cooling system  
The water pump in the engine circulates the cooling liquid. However, the cool-  
ing liquid can only circulate properly if the cooling circuit contains no air  
bubbles.  
Bleeding of the cooling system is therefore required  
a) after adding more than 0.25 l cooling liquid and  
b) after refilling the entire cooling system.  
(see Bleeding the cooling system).  
Some models are equipped with a thermostat [1] so that the engine reaches  
its operating temperature more quickly. When the engine is cold, the liquid  
coolant circulates in the cylinder and the cylinder head. As soon as the  
cooling liquid has reached a temperature of approximately 55°C, the thermo-  
stat opens and the cooling liquid is also pumped through the two aluminum  
radiators.  
1
The cooling liquid is cooled by the air stream. This means that the cooling  
effect decreases with the traveling speed. Dirty radiators additionally reduce  
the cooling effect.  
– IF POSSIBLE, ALWAYS CHECK LEVEL OF COOLING LIQUID WHEN ENGINE IS  
COLD. IF YOU HAVE TO OPEN THE RADIATOR CAP [2] WHEN THE ENGINE IS  
HOT, USE A RAG TO COVER THE CAP AND OPEN SLOWLY TO RELEASE PRES-  
SURE. CAUTION - SCALDING HAZARD.  
– DO NOT DETACH ANY RADIATOR HOSES WHILE THE ENGINE IS HOT. THE  
ESCAPING HOT COOLANT AND THE STEAM MAY CAUSE SERIOUS BURNS.  
– IN CASE YOU GET BURNT, HOLD THE AFFECTED PART OF YOUR BODY UNDER  
RUNNING COLD WATER RIGHT AWAY.  
2
– COOLANT IS TOXIC. KEEP THE COOLANT OUT OF THE REACH OF CHILDREN.  
– IN CASE COOLANT IS INGESTED, CONSULT A DOCTOR IMMEDIATELY.  
– IF COOLANT GETS INTO YOUR EYES, RINSE THEM OUT WITH WATER IMMEDI-  
ATELY AND GO SEE A DOCTOR.  
39  
Use a mixture of 50% antifreeze and 50% distilled water for the cooling liq-  
uid. The antifreeze should be designed for temperatures of at least -25°C. This  
mixture offers frost protection as well as good corrosion protection and should  
not be replaced by water alone.  
FOR THE COOLING SYSTEM, USE ONLY WITH HIGH-GRADE ANTIFREEZE (E.G.  
MOTOREX ANTI- FREEZE). USING LOWER-GRADE ANTIFREEZE AGENTS CAN CAUSE  
CORROSION AND COOLANT FOAMING.  
Pressure induced by heating of the coolant in the system is controlled by a  
valve in the radiator cap [2]; a water temperature of up to 120° C (248° F)  
is admissible without, having to expect any trouble.  
Radiator cover for the cold season  
To ensure that the engine reaches its operative temperature also at low tem-  
peratures, the radiator cover [3] must be mounted.  
For this purpose, detach the left radiator protec-  
3
tion [4] and mount the cover in front of the left radi-  
ator as illustrated.  
Remount the radiator protection.  
NOTE: The radiator shutter can be obtained  
from your KTM dealer

Checking the coolant level  
The coolant should be 10 mm (0.4 in) above the radiator fins when the engine  
is cold (see diagram). In the event of the coolant being drained, always fill  
and bleed the system.

Then immediately mount the screw so that no more air can enter the right  
radiator.

Top up the left radiator until the coolant can be seen approx. 10 mm  
(0.4 in) above the radiator fins.  
Check the coolant level again after a short ride.

Cleaning the air filter *  
The air filter must be cleaned prior to each race or whenever dust has accu-  
mulated. To clean, lift the filter box cover  
(see illustration) and pull off towards the front.  
Detach the bottom of the filter retaining bracket [4], tilt aside and remove  
the throttle cap [5] and the air filter [6] and filter support [7] from the filter  
box. The SX models do not have a throttle cap.  
– DO NOT CLEAN FOAM FILTER WITH FUEL OR PETROLEUM SINCE THESE DAM-  
AGE THE FOAM. KTM RECOMMENDS THE PRODUCTS OF THE COMPANY  
MOTOREX FOR AIR FILTER MAINTENANCE (BIO DIRT REMOVER AND LIQUID  
BIO POWER).  
– NEVER START YOUR MOTORCYCLE WITHOUT ANY AIR FILTERS. OTHERWISE,  
DUST AND DIRT MAY PENETRATE AND CAUSE DAMAGE AND INCREASED WEAR.  
– DUST AND DIRT CAN ACCUMULATE AND DAMAGE THE ENGINE IF THE AIR FIL-  
TER IS NOT MOUNTED CORRECTLY.  
Thoroughly wash the air filter in special cleaning fluid (Motorex Bio Dirt  
Remover) and allow it to dry well. Only press out the filter, do not wring it out  
under any circumstances. Oil the dry air filter with a high-grade filter oil (Motorex  
liquid Bio Power). Also clean the air filter box. Check the carburetor collar for  
damage and that it is filled correctly.  
6
Mount the air filter on the filter support. Insert the air filter and filter support  
in the throttle cap and mount them in the filter box, aligning in a central posi-  
tion, and fix with the filter retaining bracket.

Exhaust system *  
SX  
EXC  
If the end cap [1] can be removed, the silencer is filled with glass-fiber yarn.  
Have the filling checked regularly by an authorized KTM workshop (see  
Lubrication and Service Chart). The insulating material fibers escape through  
the holes in the perforated pipe with time, causing the silencer to “burn out”.  
In addition to causing a higher noise-level, it will also affect the power char-  
acteristic. The insulating material suitable for your exhaust is available from  
your authorized KTM workshop.

To replace the glass-fiber yarn set [2] remove the end cap and pull off the  
outer pipe [3]. Tape a new glass-fiber yarn set to the inner tube and slide on  
the outer pipe. Mount the end cap.  
Make sure the caps are screwed on tightly. Mount the muffler stress-free before  
tightening the fixing screws.

Changing the original position of the clutch lever  
The adjusting screw [1] can be used for individual adjustment of the original  
position of the clutch lever, thus allowing adjustment to an optimal position  
for every hand size.  
Turning the adjusting screw clockwise reduces the distance between the  
clutch lever and the handlebar. Turning the adjusting screw counterclockwise  
increases the distance between the clutch lever and the handlebar.

ADJUSTMENT OF THE CLUTCH LEVER POSITION IS ONLY POSSIBLE WITHIN CER-  
TAIN LIMITS. ONLY TURN THE ADJUSTING SCREW MANUALLY AND NEVER APPLY  
EXCESSIVE FORCE.  
Checking the oil level of the hydraulic clutch  
To check the oil level in the master cylinder of the clutch remove the cover.  
For this purpose, remove screws [2] and cover [3] together with the rubber  
boot [4]. The oil level in the horizontal-standing master cylinder should be  
4 mm below the upper edge.  
If necessary, add biodegradable SAE 10 hydraulic oil (Motorex Kupplungsfluid  
75) to the 125/200 models and DOT 5.1 (Motorex Brake Fluid 5.1) brake  
fluid to the 250/300 models, available from your authorized KTM workshop.

Bleeding the hydraulic clutch *  
The clutch control needs to be bled as soon as the resistance in the clutch

lever starts to feel unresponsive. You will need a bleeder syringe (special tool)  
and biodegradable hydraulic oil. Both are available from your KTM dealer.  
Turn the handlebar until the master cylinder is in a horizontal position, remove  
the screws [6], the cover [7] and the rubber boot [8]. Fill the bleeder syringe  
[9] with a suitable fluid (see Technical Specifications - Engine). Remove the  
bleeder screw from the slave cylinder [10] and mount the bleeder syringe.  
Press oil into the system until the fluid runs out of the hole [11] in the mas-  
ter cylinder without bubbles. Occasionally extract the fluid from the master  
cylinder reservoir to keep it from overflowing.

Carburetor adjustment *  
Basic information on the original carburetor setting  
The original carburetor setting was adapted for an altitude of approx. 500 meters (1600 ft.) above sea level, and the ambient  
temperature of approx. 20° C (68° F), mainly for off-road use and central European premium-grade fuel (95 ROZ).  
Mixing ratio (2-stroke motor oil : super fuel)  
1:40 – 1:60 (depends on oil quality)  
Basic information on changing the carburetor setting  
Always start with the original carburetor setting (the provided factory setting is meant for break-in operation; after the break-in period,  
the carburetor needs to be adjusted according to the carburetor datasheet - see appendix). Essential requirements are a clean air fil-  
ter system, air-tight exhaust system and an intact carburetor. Experience has shown that adjusting the main jet, the idling jet and the  
jet needle is sufficient and that changes of other parts of the carburetor will not greatly affect engine performance.  
RULE OF THUMB: high altitude or high temperatures > choose leaner carburetor adjustment  
low altitude or low temperatures  
> choose richer carburetor adjustment  
– ONLY USE PREMIUM-GRADE GASOLINE ROZ 95 (USA = PREMIUM RON 91) MIXED WITH HIGH-GRADE TWO-STROKE ENGINE OIL. OTHER  
TYPES OF GASOLINE CAN CAUSE ENGINE FAILURE, AND WILL VOID YOUR WARRANTY.  
– ONLY USE HIGH-GRADE 2-STROKE ENGINE OIL OF KNOWN BRANDS (E. G. MOTOREX CROSS POWER 2T).  
– NOT ENOUGH OIL OR LOW-GRADE OIL CAN CAUSE EROSION OF THE PISTON. IF YOU USE TOO MUCH OIL THE ENGINE CAN START SMOK-  
ING AND FOUL THE SPARK PLUG AND THE EXHAUST CONTROL SYSTEM.  
– IN THE CASE OF A LEANER ADJUSTMENT OF THE CARBURETOR, PROCEED CAUTIOUSLY. ALWAYS REDUCE THE JET SIZE IN STEPS OF ONE  
NUMBER TO AVOID OVERHEATING AND PISTON SEIZURE.  
NOTE: If the engine does not run properly despite a changed adjustment, look for mechanical faults and check the ignition system.  
Basic information on carburetor wear  
As a result of engine vibrations, throttle valve, jet needle, and needle jet are subjected to increased wear. This wear may cause carbu-  
retor malfunction (e.g. overly rich mixture). Therefore, these parts should be replaced after 10000 kilometers (6000 miles).  
43  
Definitions  
Mixture too rich:  
Too much fuel in proportion to air.  
3
Mixture too lean:  
Not enough fuel in proportion to air.

Idling range A  
Operation with closed throttle valve. This range is influenced by the position  
of the air control screw [2] and the air control screw [3]. Only make adjust-  
ments when the engine is hot.  
To this end, slightly increase the idling speed of the engine by means of the  
air control screw. Turning it clockwise produces a higher idling speed and turn-  
ing the screw counterclockwise produces a lower idling speed. Create a round  
and stable engine speed using the air control screw (basic position of the air  
control screw = open by 1.5 turns). Then adjust to the normal idling speed

Opening up B  
Engine behavior when the throttle opens. The idle jet and the shape of the  
throttle valve influences this range. If, despite good idling-speed and part-  
throttle setting, the engine sputters and smokes when the throttle is fully opened  
and develops its full power not smoothly but suddenly at high engine speeds,  
the mixture to the carburetor will be too rich, the fuel level too high or the  
float needle is leaking.

MAINTENANCE WORK ON CHASSIS AND ENGINE »  
Part-throttle range C  
main jet  
Operation with partly open throttle valve. This range is only influenced by the  
jet needle (shape and position). The optimum part-throttle setting is controlled  
by the idling setting in the lower range and by the main jet in the upper range.  
If the engine runs on a four-stroke cycle or with reduced power when it is  
accelerated with the throttle partly open, the jet needle must be lowered by  
one notch. If then the engine pings, especially when accelerating under full  
power at maximum engine revs, the jet needle should be raised.  
If these faults should occur at the lower end of the part throttle range at a  
four-stroke running, make the idling range leaner; if the engine pings, adjust  
the idling range richer.

Draining the float chamber of the carburetor  
Following every wet-cleaning procedure, the float chamber of the carburetor  
should be drained in order to remove any water that may have penetrated into  
it. Water in the float chamber leads to engine malfunction.  
Make sure you do this while the engine is cold. Close the fuel tap, and place  
a cloth under the carburetor, which is capable of absorbing the leaking fuel.  
Unscrew the plug [1] and clean it with compressed air. Then, mount the plug  
together with the gasket, open the fuel tap, and check the float  
chamber for leaks.  
FUEL IS EASILY FLAMMABLE AND TOXIC. WHEN HANDLING FUEL, BE SURE TO  
EXERCISE THE UTMOST CAUTION. NEVER PERFORM ANY WORK ON THE FUEL SYS-  
TEM NEAR OPEN FLAMES OR BURNING CIGARETTES. ALWAYS ALLOW THE ENGINE  
TO COOL OFF FIRST. IMMEDIATELY CLEAN UP ANY FUEL WHICH MAY HAVE BEEN  
SPILLED. MATERIALS SATURATED WITH FUEL ARE ALSO EASILY FLAMMABLE. IN  
CASE YOU INGESTED FUEL OR FUEL SPLASHED INTO YOUR EYES, CONSULT A  
DOCTOR IMMEDIATELY.  
1
DISPOSE OF THE FUEL PROPERLY.  
Checking the float level *  
Arrange the carburetor diagonally at about 60° so that the spring in the float  
needle valve is not pressed together. In this position, the edge of the float  
should be parallel with the float chamber sealing surface (see illustration).

To mount, tilt the motorcycle approx. 45° to the left, remove both screws [2],  
lift off the closing cover [3] and remove the springs including the spring insert  
[4] from the clutch cover. Pull both springs off the spring insert, mount the  
red or the green auxiliary spring and the control spring [5] and slide both into  
the clutch cover until the recess in the spring insert [4] engages in the rocker  
arm. Check the O-ring in the closing cover mount the closing cover, ensuring  
that the dolly screw [6] engages in the auxiliary spring.

Make sure you do not turn the dolly screw since this will impair the engine  
characteristic.  
If you prefer a smoother engine power application, you can mount a different  
ignition rotor and a different exhaust. Ask your KTM dealer for more  
information.

Check transmission oil level (125/200)  
In order to check the transmission oil level the control screw [1] on the clutch  
cover is to be removed. Oil should just barely escape from the inspection open-  
ing when the motorcycle is in an upright position. If necessary, remove the  
plug [2] and top up with oil (e. g. Motorex Top Speed 4T 15W50).

CLEANING »  
Clean your motorcycle regularly in order to maintain the beauty of its plastic surfaces.  
The best manner would be to use warm water that has been mixed with a normal brand-name washing detergent and a sponge.  
The hard dirt can be removed before washing with the help of a soft water jet.  
IF USING A POWER WASHER, DO NOT POINT THE WATER JET AT THE ELECTRIC COMPONENTS, PLUGS, CABLES, BEARINGS, CARBURETOR,  
ETC. THE HIGH PRESSURE WILL CAUSE WATER TO PENETRATE INTO THE COMPONENTS AND CAN CAUSE THEM TO MALFUNCTION OR LEAD  
TO PREMATURE WEAR.  
– Before cleaning with water, plug the exhaust pipe to prevent water ingress.  
– You should use normal brand-name detergents to clean the motorcycle. Especially dirty parts should also be cleaned with the help  
of a paint brush.  
– After the motorcycle has been rinsed with a soft water jet, it should be dried by air pressure and a cloth. Then take a short drive  
until the engine has reached the working temperature and also use the brakes. By warming these components, the residual water  
can evaporate from inaccessable parts of the engine and the brakes.  
– Slide back the protective covers on the handlebar-mounted instruments so that any water that may have seeped into this part of  
the motorcycle is allowed to evaporate.  
– After the motorcycle has cooled down, oil and grease all the gliding bearing parts. Treat the chain with a chain spray.  
– To prevent failures in the electric system, you should treat the ignition lock, the emergency OFF switch, the short circuit button,  
the light switch and the socket connectors with contact spray.  
CONSERVATION FOR WINTER OPERATION »  
In the event that the motorcycle is also used in winter and on roads where one has to expect salt spraying, you will have to take pre-  
cautions against the aggressive road salt.  
– clean the motorcycle thoroughly and let it dry after each ride  
– treat the engine, carburetor, swing arm, and all other bare or galvanized parts (except for brake discs) with a wax-based anti-corro-  
sion agent.  
47  
KEEP THE ANTI-CORROSION AGENT FROM GETTING INTO CONTACT WITH THE BRAKE DISCS, OTHERWISE THIS WILL SIGNIFICANTLY REDUCE  
THE BRAKING POWER.  
AFTER RIDES ON SALTED ROADS, CLEAN MOTORCYCLE THOROUGHLY WITH COLD WATER AND LET IT DRY WELL.  
STORAGE »  
Should you wish to make a pause over a longer space of time, please observe the following instructions:  
– Clean motorcycle thoroughly (see chapter: CLEANING)  
– Change engine oil (old engine oil contains aggressive contaminants).  
– Check antifreeze and amount of cooling liquid.  
– Let the engine warm up again, close fuel cock and wait until the engine dies off by itself. In this way the carburetor jets are pre-  
vented from becoming resin- clogged by the old fuel.  
– Remove spark plug and fill in approx. 5 ccm of engine oil into the cylinder through the opening. Actuate kick-starter 10 times in  
order to distribute the oil onto the cylinder walls and mount the spark plug.  
– Let fuel flow out of tank into an appropriate container.  
– Correct tire pressure.  
– Lubricate bearing points of the control levers, footrests, etc. as well as the chain.  
– The storage place should be dry and not be subjected to too big temperature fluctuations.  
– Cover the motorcycle with an air permeated tarp or blanket. Do not use non airtight materials as a possible humidity might not be  
able to escape and thereby cause corrosion.  
IT WOULD BE VERY BAD TO LET THE ENGINE RUN FOR A SHORT TIME DURING THE STORAGE PERIOD. THE ENGINE WOULD NOT GET WARMED  
UP ENOUGH AND THE THUS DEVELOPED STEAM WOULD CONDENSE DURING THE COMBUSTION PROCESS AND CAUSE THE VALVES AND EXHAUST  
TO RUST.  
USE AFTER A PERIOD OF STORAGE  
– Fill up the tank with fresh fuel.  
– Check the motorcycle as before each start (see driving instructions)  
– Take a short, careful test ride first.  
NOTE: Before you put your motorcycle away for the winter, you should check all parts for their function and wear. Should any service  
jobs, repairs, or any refitting be necessary, you should have them carried out during the off-season (lower workload at mechanics' shops).  
This way, you can avoid the long waiting times at your shop at the beginning of the next biking season.
