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 sport 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 motorcycle 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-
cycle 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. If maintenance work should become necessary during a competition
it should be performed by a trained mechanic. KTM strongly recommends that all service work to your
KTM should be performed by a qualified KTM dealer.
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. To ensure that all work to your KTM
is performed properly and to avoid warranty conflicts, KTM recommends that you always have your KTM
serviced by a recognized and qualified KTM dealer.
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 environmen-
tally conscious and respect the rights of others.
We wish you a lot of fun when driving !

– THE FASTER YOU DRIVE, THE MORE SENSITIVE YOUR MOTORCY-
CLE WILL BE TO CROSSWIND AND CHANGING ROAD CONDITIONS.
YOUR MOTORCYCLE CAN EASILY GO OUT OF CONTROL AT HIGH
SPEEDS.
– CHOOSE YOUR DRIVING SPEED ACCORDING TO THE CONDITIONS
AND YOUR DRIVING SKILLS.
– DRIVE CAREFULLY ON UNKNOWN ROADS OR ON UNFAMILIAR
TRIALS.
– RENEW THE VIZOR ON YOUR HELMET OR THE GLASS OF YOUR
GOGGLES ON TIME SO AS TO ENSURE OPTIMUM VISION IN ANY
SITUATION. WHEN LIGHT SHINES DIRECTLY ON SCRATCHED VISOR
OR GOGGLES, THE OPERATOR WILL BE BLINDED.
– NEVER LEAVE YOUR MOTORCYCLE WITHOUT SUPERVISION IF THE
ENGINE IS RUNNING.
– Hold the handlebars 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.
– 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 changes in the weight distribu-
14
tion. Read the section on "Accessories and payload“ when car- Accessories and payload
rying luggage.
Accessory parts and baggage can significantly decrease a motor-
cycle's driving stability. Please observe the following warnings.
– Pay attention to running-in procedure.
Running in the LC8 engine
– NEVER DRIVE FASTER THAN 130 KPH (80 MPH) IF YOU HAVE
MOUNTED ACCESSORY PARTS ON YOUR MOTORCYCLE. ACCESSORY
PARTS CAN SIGNIFICANTLY IMPAIR THE MOTORCYCLE'S HAN-
DLING, ESPECIALLY IN THE MAXIMUM SPEED RANGE.
– NEVER DRIVE FASTER THAN 130 KPH (80 MPH) IF YOUR MOTOR-
CYCLE IS LOADED WITH CASES OR OTHER BAGGAGE. THEY WILL
IMPAIR THE MOTORCYCLE'S HANDLING AT HIGHER SPEEDS AND
CAN EASILY CAUSE IT TO GO OUT OF CONTROL
– IF YOU HAVE CASES MOUNTED, DO NOT EXCEED THE MANUFAC-
TURER'S RECOMMENDED MAXIMUM PAYLOAD.
– FASTEN THE BAGGAGE CLOSE TO THE CENTER OF THE MOTOR-
CYCLE AND DISTRIBUTE THE WEIGHT EVENLY ON THE FRONT AND
REAR WHEELS AND ON THE LEFT AND RIGHT.
– BAGGAGE MUST BE SECURELY AND ADEQUATELY FASTENEND;
LOOSE BAGGAGE WILL SIGNIFICANTLY IMPAIR DRIVING SAFETY.
– A HIGH PAYLOAD WILL CHANGE THE MOTORCYCLE'S HANDLING
AND CONSIDERABLY INCREASE THE BRAKING DISTANCE; ADAPT
YOUR DRIVING SPEED ACCORDINGLY.
– NEVER EXCEED THE MAXIMUM PERMISSIBLE LADEN WEIGHT
AND THE AXLE WEIGHTS. THE MAXIMUM PERMISSIBLE LADEN
WEIGHT IS MADE UP OF THE FOLLOWING COMPONENTS:
– MOTORCYCLE READY FOR OPERATION AND TANK FULL
– LUGGAGE
Even finely machined surfaces of engine parts have rougher sur-
faces than parts that slide on each other for a long time. Therefore,
every engine must be run in. For this reason, do not demand max-
imum performance from the engine for the first 1000 kilometers
(620 miles). The vehicle must be run in at low, changing perform-
ance level for the first 1000 km (620 miles). The maximum num-
ber of revolutions per minute must not go exceed 6500 rpm. Once
you have run your engine in for 1000 km, you may push it to its
9500 rpm limit , i.e. up to the black zone indicated in the tachome-
ter. Exceeding the above listed rotations as well as pushing high
rpm when the engine is cold will have an adverse effect on the life
of your engine.
– WEAR SUITABLE CLOTHING WHEN DRIVING A MOTORCYCLE.
CLEVER KTM DRIVERS ALWAYS WEAR A HELMET, BOOTS, GLOVES
AND A JACKET, REGARDLESS OF WHETHER DRIVING ALL DAY OR
JUST FOR A SHORT TRIP. THE PROTECTIVE CLOTHING SHOULD
BE BRIGHTLY COLORED SO THAT OTHER VEHICLE CAN SEE YOU
AS EARLY AS POSSIBLE. YOUR PASSENGER WILL ALSO NEED
SUITABLE PROTECTIVE CLOTHING.
– DO NOT DRIVE AFTER HAVING CONSUMED ALCOHOL.
– ALWAYS TURN ON THE LIGHT TO MAKE SURE THAT OTHER DRIV-
ERS BECOME AWARE OF YOU AS EARLY AS POSSIBLE.
–
DRIVER AND PASSENGER WITH PROTECTIVE CLOTHING AND HELMET
– DRIVE AT A MODERATE SPEED FOR THE FIRST FEW KILOMETERS
OF EACH TRIP TO ALLOW THE TIRES TO REACH THE NECESSARY
OPERATING TEMPERATURE. MAXIMUM ROAD GRIP IS ASSURED
WHEN THE TIRES ARE WARM.
– THE FRONT AND REAR WHEEL ARE ALLOWED TO BE FITTED ONLY
WITH TIRES THAT HAVE THE SAME PROFILE TYPE.
– THE TIRES MUST BE DESIGNED FOR A SPEED OF OVER 240 KPH
(SPEED SYMBOL ZR) AND MUST BE RELEASED BY KTM.
– DO NOT EXCEED THE RESPECTIVE MAXIMUM SPEED FOR TIRES
DESIGNED WITH A SPEED INDEX OF LESS THAN "V“ (240 KPH).
A STICKER SHOWING THE MAXIMUM SPEED MUST BE AFFIXED
TO THE MOTORCYCLE WITHIN THE DRIVER'S FIELD OF VISION.

DRIVING INSTRUCTIONS »
Check the following before each start
When you start, the motorcycle must be in perfect mechanical condition. For
safety reasons, you should make a habit of performing an overall check of
your motorcycle before each start.
The following checks should be performed:
1
FUEL
Check the fuel quantity in the tanks.
2
CHAIN
Check the tension and condition of the chain.
A loose chain can fall off the sprockets and a worn-out chain can tear. In
both cases this can damage other motorcycle components and cause the
motorcycle to go out of control. A chain that is too tight or not greased
will cause unnecessary wear to the chain and sprockets.
3
4
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. Check for sufficient
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 brake pads.
Arrange for the braking system to be checked by a KTM specialist, as com-
plete failure of the braking system can be avoided.
15
Also check the state of the brake hose and the thickness of the brake
linings.
Check free travel at hand brake lever and foot brake lever.
5
6
7
CABLES
Check the throttle cable for correct adjustment and smooth operation.
COOLING FLUID
Check the level of cooling fluid when the engine is cold.
ELECTRICAL SYSTEM
Start the engine and check the headlight, tail lamp, brake light, turn sig-
nals, indicator lamps, horn and emergency-off switch for proper
functioning.
8
9
CHECK OIL LEVEL
Insufficient oil results in premature wear and consequently to engine
damage.
BAGGAGE, PAYLOAD
Never exceed the maximum total weight (380 kg, 838 lbs) and the motor-
cycle's wheel loads. The maximum total weight is comprised of:
– the motorcycle in a running condition and refueled (195 kg, 430 lbs)
– the baggage and accessories
– the driver and passenger with protective gear and helmet
Adjust the tire inflation pressure as well as the preload and damping prop-
erties of the fork and shock absorber to the total weight.
10 REAR MIRROR
Sit on the motorcycle and check the adjustment of the rear mirror.

Switch on emergency OFF switch [1].
Switch on ignition (turn ignition key [2] into position ).
NOTE:
You will hear the operation of the fuel pump for approx. 2 seconds after
switching on the ignition. The FI indicator lamp will also light up during
this time and the engine should not be started.
Switch transmission to idle (green indicator lamp N [3] lights up).
Do not accelerate; operate starter button [5].
The oil pressure warning lamp [4] should go out as soon as the engine is
running.
Take the load off the side stand and fold the side stand all the way up.

DO NOT START THE ENGINE AND ALLOW IT TO IDLE IN A CLOSED ROOM. EXHAUST
FUMES ARE POISONOUS AND CAN CAUSE LOSS OF CONSCIOUSNESS AND DEATH.
ALWAYS PROVIDE ADEQUATE VENTILATION WHILE THE ENGINE IS RUNNING.
– IF YOU ACCELERATE WHILE STARTING, THE ENGINE MANAGEMENT WILL NOT
INJECT ANY FUEL AND THE ENGINE WILL NOT START. DO NOT ACCELERATE
WHILE STARTING!
– IF THE OIL PRESSURE WARNING LAMP DOES NOT GO OUT AS SOON AS THE
ENGINE IS RUNNING, IMMEDIATELY SWITCH OFF THE ENGINE. IF THE ENGINE
IS NOT SWITCHED OFF, ENGINE DAMAGE WILL OCCUR WITHIN A SHORT
PERIOD OF TIME. CHECK THE ENGINE OIL LEVEL OR CONTACT A KTM
WORKSHOP.
2
– MAXIMUM PERIOD FOR CONTINUOUS STARTING: 5 SECONDS. WAIT AT LEAST
5 SECONDS BEFORE TRYING AGAIN.
– DON’T RIDE YOUR MOTORCYCLE WITH FULL LOAD AND DON’T REV ENGINE
WHEN COLD. BECAUSE THE PISTON IS WARMING UP FASTER THAN THE
WATER COOLED CYLINDER, IT CAN CAUSE ENGINE DAMAGE. ALWAYS LET THE
ENGINE WARM UP BEFORE AND REFRAIN FROM DRIVING WITH FULL LOAD
UNTIL THE ENGINE IS WARM.
16

IF THE ENGINE IS DOES NOT CRANK WHEN YOU ACTUATE THE STARTER
TIP SWITCH:
– the transmission is switched to idle
– Check if the emergency OFF switch is on
– Check if the ignition is on
– the headlight is on (Light switch in
position).
– If this is not the case, the battery is discharged
– If the lights are on, proceed as described in the „Trouble-shooting“
section or contact a KTM dealer.
4
IF THE ENGINE CRANKS BUT DOES NOT START, WHEN YOU ACTUATE THE
STARTER TIP SWITCH:
– whether you accelerated while starting
– whether the FI indicator lamp is blinking
– if yes, check Troubleshooting - Blink codes table
– Check if sufficient fuel is in the tank
– If this is not the case, refill the tank
– if sufficient fuel is in the tank, proceed as described in the „Trouble-
shooting“ section or contact a KTM dealer.
NOTE:
5
This motorcycle is equipped with a safety starting system. The engine can
only be started if the transmission is in neutral or the clutch lever is pulled.
If the side stand is folded down, the engine can only be started if the trans-
mission is in neutral or the clutch lever is pulled. The engine will stall if a
gear is engaged and the clutch lever is released with the side stand folded
down.

DRIVING INSTRUCTIONS »
– NEVER USE YOUR MOTORCYCLE WITHOUT AN AIR FILTER.
OTHERWISE DUST AND DIRT MAY ENTER THE ENGINE AND CAUSE
INCREASED WEAR.
– STOP IMMEDIATELY IF A PERCEPTIBLE POWER LOSS OCCURS
WHILE DRIVING DUE TO A DEFECTIVE IGNITION CAUSED BY A
CYLINDER MISFIRING OR BREAKING DOWN. IF THE UNBURNED
FUEL/AIR MIXTURE REACHES THE CATALYTIC CONVERTER, IT WILL
IGNITE AND THE RESULTING HEAT WILL DESTROY THE CATALYTIC
CONVERTER AND THE ADJOINING COMPONENTS.
– THE RED COOLANT WARNING LAMP LIGHTS UP WHEN THE COOLANT
TEMPERATURE HAS REACHED 120°C (248°F).
POSSIBLE CAUSES FOR THE INCREASE IN TEMPERATURE:
– LOW DRIVING VELOCITY AND HIGH LOAD SITUATION IN HIGH AIR
TEMPERATURES
Starting off
Turn on the light, pull the clutch lever and engage 1st gear. Slowly
release the clutch lever while you gently accelerate.
– BEFORE YOU START OFF, CHECK THAT THE MAIN STAND HAS BEEN
SWUNG UP FULLY. IF THE STAND DRAGS ON THE GROUND, THE
MOTORCYCLE CAN GO OUT OF CONTROL.
– ALWAYS TURN ON THE LIGHT WHEN YOU DRIVE. OTHER DRIVERS
WILL BE ABLE TO SEE YOU MUCH SOONER.
– DO NOT ATTACH A HELMET OR OTHER OBJECTS TO THE HELMET
LOCK ROPE WHILE DRIVING. YOU CAN EASILY LOSE CONTROL OF
THE MOTORCYCLE.
– LEVEL OF COOLANT IN THE SYSTEM IS INSUFFICIENT
– FAN AT RADIATOR IS NOT RUNNING
–
IMPROPER USE OF THE CLUTCH WHILE DRIVING AT LOW VELOCITIES
Shifting/Riding
LET THE ENGINE COOL DOWN. MEANWHILE, CHECK WHETHER ANY
COOLING LIQUID IS LEAKING OUT OF THE MOTORCYCLE. CHECK
THE COOLING LIQUID LEVEL IN THE RADIATOR (NOT ONLY IN THE
COMPENSATING TANK). - CAUTION SCALDING HAZARD! DO NOT
DRIVE ON, UNTIL THERE IS SUFFICIENT LIQUID IN THE COLING
SYSTEM.
– 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.
You are now in first gear, refered to as the drive or uphill gear.
Depending on the conditions (traffic, road gradient, etc.), you can
shift to a higher gear. Close throttle, at the same time pull clutch
lever and shift to the next higher gear. Let clutch lever go again
and open throttle. Do not shift gears and accelerate carefully in
curves.
Only accelerate to the extent that road and weather conditions allow.
Be especially careful when you accelerate in curves. Abrupt open-
ing of the throttle can cause the motorcycle to go out of control
and also increases fuel consumption.
By shifting down, use the brakes if necessary and close throttle at
the same time. Pull clutch lever and shift down to the next gear.
Let clutch lever go slowely and open throttle or shift down again.
If the engine is killed f.ex. at a crossing, simply pull the clutch
lever and start. It is not necessary to switch the gear to NEUTRAL.
Stop immediately if the FI indicator lamp lights up while driving.
The FI indicator lamp will start blinking as soon as the transmis-
sion is in neutral. The rhythm of the blinking lamp will let you deter-
mine the two-digit "blink code", e.g.:
Braking
Close throttle and apply the hand and foot brakes at the same time.
Carefully apply the brakes on sandy, wet or slippery surfaces.
Always brake with feeling, blocking wheels can cause you to skid
or fall. Also change down to lower gears depending on your speed.
Always finish braking before you enter a curve.
17
When driving downhill, use the braking effect of the engine. Change
down one or two gears but do not overspeed the engine. In this
way, you will not need to brake so much and the brakes will not
overheat.
Blink code 34: FI blinks 3x long, 4x short, pause,
Blink code 06: FI blinks 6x short, pause
The blink code will indicate which component is defective (see
Troubleshooting). This makes it possible to pinpoint the defect if
a diagnostic tool is unavailable.
– IN THE RAIN, OR AFTER THE MOTORCYCLE HAS BEEN WASHED,
BRAKING ACTION MAY BE DELAYED DUE TO WET BRAKE DISCS.
FIRST, THE BRAKES MUST BE BRAKED DRY.
– ON SALT-SPRAYED OR DIRTY ROADS BRAKE ACTION MAY BE
DELAYED AS WELL. FIRST, THE BRAKES MUST BE BRAKED CLEAN.
– REMEMBER THAT THE STOPPING DISTANCE WILL BE LONGER IF
YOU ARE CARRYING A PASSENGER OR BAGGAGE.
– WHEN YOU BRAKE, THE BRAKE DISCS, BRAKE PADS, BRAKE
CALIPER AND BRAKE FLUID HEAT UP. THE HOTTER THESE PARTS
GET, THE WEAKER THE BRAKING EFFECT. IN EXTREME CASES,
THE ENTIRE BRAKING SYSTEM CAN FAIL.
– AVOID ABRUPT LOAD CHANGES WHILE RIDING AROUND BENDS
AND ON WET OR SLIPPERY GROUND. OTHERWISE YOU MIGHT
EASILY LOSE CONTROL OVER YOUR MOTORCYCLE.
– WHILE RIDING YOUR MOTORCYCLE, NEVER SWITCH THE IGNITION
LOCK TO POSITIONS
AND
.
– DO NOT TRY TO CHANGE THE SETTINGS WHILE DRIVING. YOUR
ATTENTION WILL BE DISTRACTED FROM THE TRAFFIC AND MAY
CAUSE YOU TO LOSE CONTROL OF YOUR MOTORCYCLE.
– THE PASSENGER MUST HOLD ON TO THE DRIVER OR THE HOLD-
ING STRAP ON THE SEAT WHILE RIDING AND KEEP HIS/HER FEET
ON THE PASSENGER FOOTRESTS.
– REGULARLY MAKE SURE THAT THE BAGGAGE AND CASES ARE
TIGHTLY FASTENED.
– AFTER FALLING WITH THE MOTORCYCLE, CHECK ALL FUNCTIONS
THOROUGHLY BEFORE STARTING UP OPERATIONS AGAIN.
– A BENT HANDLEBAR MUST ALWAYS BE REPLACED. NEVER TRY TO
STRAIGHTEN THE HANDLEBAR BECAUSE THIS WILL CAUSE IT TO
LOSE ITS STABILITY.
– HIGH RPM RATES WHEN THE ENGINE IS COLD HAVE AN ADVERSE
EFFECT ON THE LIFE OF YOUR ENGINE. WE RECOMMEND YOU RUN
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 BE TAKEN. THE ENGINE HAS
REACHED OPERATING TEMPERATURE AS SOON AS THE SECOND
BAR ON THE TEMPERATURE INDICATOR LIGHTS UP.
– IF THE RED OIL PRESSURE WARNING LAMP LIGHTS UP WHILE DRIV-
ING, THE OIL PRESSURE IS TOO LOW TO ADEQUATELY LUBRICATE
THE ENGINE. STOP IMMEDIATELY AND SWITCH OFF THE ENGINE.
IF YOU CONTINUE TO DRIVE, ENGINE DAMAGE WILL OCCUR WITHIN
A SHORT PERIOD OF TIME. CHECK THE ENGINE OIL LEVEL OR CON-
TACT AN AUTHORIZED KTM WORKSHOP.
– NEVER HAVE THE THROTTLE WIDE OPEN WHEN CHANGING DOWN
TO A LOWER GEAR. THE ENGINE WILL OVERSPEED, DAMAGING THE
VALVES. IN ADDITION, THE REAR WHEEL BLOCKS SO THAT THE
MOTORCYCLE CAN EASILY GET OUT OF CONTROL.

Stopping and parking
Apply the brakes fully and put the engine into neutral. To stop the engine,
switch off the ignition. Fold the side stand forward to the stop with your foot,
put the weight of the motorcycle on the stand and park the bike on a firm sur-
face. Lock the motorcycle.
– ALWAYS PARK YOUR MOTORBIKE ON A SOLID AND HORIZONTAL
SURFACE.
– NEVER LEAVE YOUR MOTORCYCLE WITHOUT SUPERVISION AS LONG AS THE
ENGINE IS RUNNING.
– MOTORCYCLE ENGINES PRODUCE A GREAT AMOUNT OF HEAT WHILE RUN-
NING. THE ENGINE RADIATORS, EXHAUST, EXHAUST SYSTEM, BRAKE DISCS,
AND SHOCK ABSORBERS CAN BECOME VERY HOT. DO NOT TOUCH ANY OF
THESE PARTS AFTER OPERATING THE MOTORCYCLE, AND TAKE CARE TO PARK
IT WHERE PEDESTRIANS ARE NOT LIKELY TO TOUCH IT AND GET BURNED
– NEVER PARK YOUR MOTORCYCLE IN PLACES WHERE THERE EXIST FIRE HAZ-
ARDS DUE TO DRY GRASS OR OTHER EASILY FLAMMABLE MATERIALS.
– ALWAYS TAKE OUT THE IGNITION KEY WHEN PARKING YOUR MOTORCYCLE
SO THAT IT CANNOT BE USED BY UNAUTHORIZED PERSONS.
– THE SIDE STAND IS DIMENSIONED FOR THE WEIGHT OF THE MOTORCYCLE
ONLY. SITTING ON THE MOTORCYCLE WILL INCREASE THE WEIGHT ON THE
SIDE STAND. THE SIDE STAND OR ENGINE CASE CAN BE DAMAGED AND THE
MOTORCYCLE CAN TIP OVER.

MAINTENANCE WORK ON CHASSIS AND ENGINE »
ALL MAINTENANCE AND ADJUSTMENT WORK MARKED WITH AN ASTERISK * REQUIRES SPECIAL TECHNICAL SKILLS. IN YOUR OWN INTE-
REST, HAVE THIS WORK PERFORMED BY AN AUTHORIZED KTM WORKSHOP, WHERE YOUR MOTORCYCLE WILL BE SERVICED BY SPECIALLY
TRAINED TECHNICIANS.
– DO NOT CLEAN THE MOTORCYCLE WITH A POWER WASHER OTHERWISE WATER WILL GET INTO THE BEARINGS, ELECTRIC SOCKET CON-
NECTORS, ETC.
– USE SPECIAL KTM SCREWS WITH THE CORRECT THREAD LENGTH TO FASTEN THE SPOILER TO THE TANK. MOUNTING OTHER SCREWS
OR LONGER SCREWS COULD PUNCTURE THE TANK AND CAUSE FUEL TO LEAK OUT.
– IF YOU DISCONNECT SOCKET CONNECTORS WITH SELF-LOCKING NUTS, REPLACE THEM BEFORE REMOUNTING. IF NO NEW SELF-
LOCKING NUTS ARE AVAILABLE, APPLY LOCTITE 243 TO THE THREAD OF THE OLD NUTS. IF THE THREAD IS DAMAGED, REPLACE THE
SCREWS AND NUTS.
– DO NOT USE TOOTHED DISKS OR SPLIT WASHERS FOR THE ENGINE FASTENING BOLTS SINCE THEY WILL WORK THEIR WAY INTO THE
FRAME COMPONENTS AND BECOME LOOSE. ALWAYS USE SELF-LOCKING NUTS.
– LET THE MOTORCYCLE COOL DOWN BEFORE SERVICING TO AVOID BEING BURNED.
– PROPERLY DISPOSE OF OILS GREASE, FILTERS, FUEL, CLEANSERS, ETC. OBSERVE THE REGULATIONS EFFECTIVE IN YOUR COUNTRY.
– NEVER POUR USED OIL IN THE SEWER OR DISPOSE OF IT OUTDOORS. 1 LITER OF USED OIL WILL POLLUTE 1,000,000 LITERS OF WATER.

Adjusting the fork and shock absorber
There are a number of ways to adjust the fork and shock absorber to match
the chassis to your driving style and the payload.
BASIC SETTING
FORK
990 SUPER DUKE
We have provided a table with pragmatical values to help you tune up your
motorcycle. These tune-up specifications are reference values only and should
serve as a basis for your personal chassis and suspension tuning. Do not make
arbitrary changes to the settings (maximum ±40%) since this may impair the
handling characteristics (particularly in the high-speed range).
Make sure both fork legs are equally adjusted.

Adjusting compression damping of fork
Hydraulic compression damping determines the reaction when the fork is com-
pressed.
Turn the adjusting screws [1] clockwise to increase damping, turn it counter-
clockwise to reduce damping during compression.
STANDARD ADJUSTMENT
– Turn adjusting screw clockwise as far as it will go.
– Turn 15 clicks in a counterclockwise direction.
1
Adjusting rebound damping of fork
Hydraulic rebound damping determines the reaction when the fork is
rebound. By turning the adjusting screw [2] (REB), the degree of damping of
the rebound can be adjusted. Turn the knob clockwise to increase damping,
turn it counterclockwise to reduce damping during rebounding. Make the same
damping rate adjustment to both fork legs.
2
STANDARD ADJUSTMENT
– Turn adjusting screw clockwise as far as it will go.
– Turn 15 clicks in a counterclockwise direction.

MAINTENANCE WORK ON CHASSIS AND ENGINE »
Adjusting the spring preload on the fork
The fork spring preload can be adjusted by turning the adjusting screws [1]
(wrench size 24 mm) ± 5 mm (0,2 in).
Turning in a clockwise direction will increase the preload, turning in a coun-
terclockwise direction will decrease the preload. 1 turn will change the pre-
load by 1 mm.
1
Changing the preload will not affect the rebound damping adjustment, although
adjusting screw [2] will turn at the same time.
Generally, if the preload is higher, the rebound damping should also be set
higher.
2
STANDARD ADJUSTMENT:
– Turn adjusting screw counterclockwise as far as it will go.
– Turn 5 turns in a clockwise direction.

Compression damping of shock absorber
The shock absorber 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 compres-
sion rates.
The high-speed setting is effective at fast compression rates.
Turning in a clockwise direction will increase the damping, turning counter-
clockwise will decrease the damping.
STANDARD ADJUSTMENT LOW-SPEED:
– Turn adjusting screw [3] clockwise as far as it will go.
– Turn 20 clicks in a counterclockwise direction.
3
STANDARD ADJUSTMENT HIGH-SPEED:
– Turn adjusting screw (wrench size 17 mm) clockwise as far as it will go.
– Turn 2 turns in a counterclockwise direction.
THE DAMPING UNIT OF THE SHOCK ABSORBER IS FILLED WITH HIGH-COMPRES-
SION NITROGEN. NEVER TRY TO TAKE THE SHOCK ABSORBER APART OR TO DO
ANYMAINTENANCE WORK YOURSELF. SEVERE INJURIES COULD BE THE RESULT.
NEVER UNSCREW THE BLACK SCREW CONNECTION (24MM).

THE DAMPING UNIT OF THE SHOCK ABSORBER IS FILLED WITH HIGH-COMPRES-
SION NITROGEN. NEVER TRY TO TAKE THE SHOCK ABSORBER APART OR TO DO
ANY MAINTENANCE WORK YOURSELF. SEVERE INJURIES COULD BE THE RESULT.
Checking the chain tension
Place the motorcycle on the side stand. Switch the transmission to neutral
and push the chain up. The distance between the chain and the swing arm
should be 7 mm when the upper part of the chain [A] is tensioned (see draw-
ing). Correct the chain tension if necessary.

– IF CHAIN TENSION IS TOO GREAT, PARTS WITHIN THE SECONDARY POWER
TRANSMISSION (CHAIN, CHAIN SPROCKETS, TRANSMISSION AND REAR WHEEL
BEARINGS) WILL BE SUBJECTED TO UNNECESSARY STRESS, RESULTING IN
PREMATURE WEAR AND EVEN CHAIN BREAKAGE.
7 mm
– 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.
24
Correcting the chain tension
Loosen the collar nut [2], loosen the counternuts [3] and turn the left and
right adjustment screws [4] the same distance. Tighten the counternuts [3].
To make sure the rear wheel is aligned, the marks on the chain tensioners
must be in the same position on the left and right in relation to the reference
marks [A]. Before tightening the wheel spindle make sure the chain tensioner
[5] rests against the adjustment screws and the rear wheel is aligned with the
front wheel.

IF YOU DON’T HAPPEN TO HAVE A TORQUE WRENCH AT HAND, MAKE SURE YOU
HAVE THE TIGHTENING TORQUE CORRECTED BY A KTM DEALER AS SOON AS POS-
SIBLE. A LOOSE AXLE MAY LEAD TO AN UNSTABLE DRIVING BEHAVIOR OF YOUR
MOTORCYCLE.

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.
– THE CHAIN DOES NOT HAVE A CHAIN JOINT FOR SAFETY REASONS. ALWAYS
HAVE THE CHAIN REPLACED IN AN AUTHORIZED KTM WORKSHOP WHERE THE
SERVICE TECHNICANS HAVE THE REQUIRED RIVETING TOOL.
– NEVER MOUNT A NORMAL CHAIN JOINT.
Also check sprockets and chain guides for wear, and replace if necessary.
25
Checking the chain for wear
To check the chain for wear proceed as follows:
Switch the transmission to idle and put a load of approx. 15 kilograms
(33 lbs) on the lower part of the chain (see illustration). Now measure the
distance between 18 chain rollers on the upper part of the chain. The chain
needs to be replaced when the distance is 272 mm (10.70 in). Since chains
do not always wear evenly, repeat the measurement at different parts of the
chain.
Replace the chain if any X-rings are missing.
NOTE:
If you mount a new chain, the sprockets should also be replaced. New chains
wear faster if used on old used sprockets.

General information on KTM disk brakes
BRAKE CALIPERS:
2
1
The front brake calipers [1] have 4 brake pistons each and are firmly con-
nected to the fork legs. The front brake disks are designed as "floating" brake
disks, i.e. they are not firmly connected to the front wheel.
The lateral balance ensures that the brake pads always have the best possi-
ble contact to the brake disk. Apply Loctite 243 to the screws [2] on the brake
caliper support and tighten to 45 Nm.
The rear brake caliper [3] has 1 brake piston and is designed as a "floating
brake caliper, i.e. it is not firmly connected to the brake caliper support. The
lateral balance ensures that the brake pads always have the best possible con-
tact to the brake disk.
FOR SAFETY REASONS, ALWAYS HAVE MAINTENANCE WORK AND REPAIRS TO THE
BRAKE SYSTEM PERFORMED BY AN AUTHORIZED KTM WORKSHOP.
3
BRAKE PADS:
Your motorcycle is equipped with sintered brake pads in the front and rear
and homologated accordingly. They guarantee maximum braking
performance.
Front brake pads:
Rear brake pads:
Toshiba TT 2172 HH
Toshiba TTH 38 GF
BRAKE PADS AVAILABLE IN THE ACCESSORY TRADE ARE OFTEN NOT AUTHOR-
IZED FOR OPERATION OF YOUR KTM MOTORCYCLE IN ROAD TRAFFIC. THE BRAKE
PADS DESIGN AND FRICTION FACTOR AND THEREFORE THE BRAKING POWER CAN
DEVIATE SIGNIFICANTLY FROM ORIGINAL KTM BRAKE PADS. IF YOU USE DIFFER-
ENT BRAKE PADS THAN THOSE PROVIDED WITH THE ORIGINAL EQUIPMENT, IT
CANNOT BE WARRANTED THAT THEY ARE AUTHORIZED FOR USE IN ROAD TRAF-
FIC. YOUR MOTORCYCLE WILL NOT LONGER COMPLY WITH THE REGULATIONS
AUTHORIZING THE USE OF VEHICLES FOR ROAD TRAFFIC AND THE WARRANTY
WILL BE VOID.
26
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. There is no reason to remove the reservoir cap
under normal conditions. If the brake fluid level drops below the minimum
either the brake system has a leak or the brake pads are completely worn down.
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 that 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
by DOT 5.1.
Never use DOT 5 braking fluid. It is based on silicone oil and has a purple
color. Gaskets and brake hoses are not compatible with it.
Brake fluid is exposed to a high thermal load and absorbs moisture from the
air, which lowers the boiling point. The brake fluid should therefore be changed
at the prescribed intervals.
HAVE THE BRAKE FLUID FOR THE FRONT AND REAR BRAKE CHANGED AT AN
AUTHORIZED KTM WORKSHOP EVERY 2 YEARS.
A
BRAKE DISCS:
Wear reduces the thickness of the brake disc in the area of contact [4] with
the brake pads. The brake disk should not be thinner than 4 mm (0.16 in) at
the weakest point [A]. Check the wear at several points.
4
BRAKE DISKS THAT ARE LESS THAN 4 MM (0.16 IN) THICK ARE A SAFETY HAZ-
ARD. HAVE WORN BRAKE DISKS REPLACED IMMEDIATELY.

Adjusting the basic position of the hand brake lever
The basic position of the hand brake lever can be modified by turning the
adjusting screw [1]. This lets you adapt the position of the pressure point (the
resistance you feel on the hand brake lever when the brake pads are pressed
against the brake disk) to fit any hand.
1
AT THE HAND BRAKE LEVER, FREE TRAVEL MUST AT LEAST BE 3 MM (0.12 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 BRAK-
ING SYSTEM, AND THE FRONT WHEEL BRAKE MAY FAIL DUE TO OVERHEATING.
min. 3 mm
Checking the front brake fluid level
The brake fluid reservoir for the front brake is located on the left side of the
handlebar and has a "MIN" and a "MAX" mark. The brake fluid level may not
fall below the "MIN" mark when the vehicle is parked in a vertical position.
– IF THE BRAKE FLUID LEVEL DROPS BELOW THE MINIMUM EITHER THE BRAKE
SYSTEM HAS A LEAK OR THE BRAKE PADS ARE COMPLETELY WORN DOWN.
IN THIS CASE, CONSULT AN AUTHORIZED KTM DEALER IMMEDIATELY.
– HAVE THE BRAKE FLUID CHANGED AT AN AUTHORIZED KTM WORKSHOP

Tires, air pressure
Tire type, tire condition, and how much air pressure the tires have in them
affect the way your motorcycle rides, and they must therefore be checked when-
ever you’re getting ready to go anywhere on your motorcycle.
FOR DRIVING SAFETY AND MAXIMUM HANDLING, ONLY USE TIRES AUTHORIZED
BY KTM CORRESPONDING TO THE "ZR" SPEED INDEX (OVER 240 KPH). OTHER
TIRES CAN HAVE A NEGATIVE EFFECT ON THE MOTORCYCLE'S HANDLING (E.G.
CAN CAUSE IT TO "WOBBLE" AT HIGHER SPEEDS).
– Tire type and size can be found in the technical specifications and in the
homologation certificate
– Tire condition has to be checked every time you want to ride your motor-
cycle. Before leaving check for punctures and nails or other sharp objects
that might have become embedded in the tire.
– Refer to the specific regulations in your country for minimum tire tread
requirements. We recommend replacing 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. Adapt the air
pressure to the motorcycle's total weight. Proper pressure ensures opti-
mum driving comfort and extends the life of your tires.

Charging the battery
Note: a battery charger, item no. 58429074000, is available from your KTM
dealer. You can also use the battery charger to test the off load voltage, starta-
bility of the battery and the generator capacity.
Remove the front spoiler and fold the battery cover down; then determine the
battery's charge condition. To determine the charge condition, use a voltmeter
to measure the voltage between the battery terminals (off load voltage). For
a precise measurement, the battery should not have been charged or discharged
for at least 30 minutes.
4
If the voltage exceeds 12.4 V, it does not need to be charged.
If the voltage is below 12.4 V, the battery should be charged.
CHARGING:
Disconnect the negative terminal from the battery to avoid damage to the motor-
cycle's electronic system.
Connect the battery charger to the battery terminals. First connect the cables
to the positive terminal, then to the negative terminal on the battery. Charge
the battery for 5 to a max. of 10 hours with 1.4 amperes and a max. of 14.4
volts. For a quick charge, do not charge the battery with 4.5 amperes and a
max. of 14.4 volts for more than 1 hour.

Cooling system
The water pump in the engine ensures a forced circulation of the cooling liq-
uid. When the engine is cold, the cooling liquid only circulates in the cylin-
ders and cylinder heads. After the engine reaches the operating temperature
(approx. 75°C, 167°F), the thermostat opens and the cooling liquid is also
pumped through the aluminum radiator.
Cooling is by means of the air stream. The lower the speed, the lower the cool-
ing effect. Soiled cooling fins also impair the cooling effect.
If, for example, slow urban traffic or waiting at a traffic light cause little or
no air to stream through the radiator, the temperature of the cooling liquid
will rise. The radiator fan [1] switches on when the cooling liquid reaches a
temperature of 102°C (216°F). Additional air is blown through the radiator
to prevent the cooling system from overheating.
1
THE TEMPERATURE INDICATOR [2] WILL BEGIN TO BLINK AND THE RED COOL-
ING LIQUID TEMPERATURE WARNING LAMP [3] WILL LIGHT UP WHEN THE COOL-
ING LIQUID REACHES APPROX. 120°C (248°F), HAVING EXCEEDED THE NORMAL
OPERATING TEMPERATURE. POSSIBLE CAUSES:
– SLOW RIDING WITH LARGE LOADS AT A HIGHER AIR TEMPERATURE:
IF POSSIBLE INCREASE YOUR RUNNING SPEED, SO THAT MORE AIR CAN BLOW
THROUGH THE RADIATORS. SHOULD THE WARNING LIGHT STILL BE ON OFF
AFTER 1500 METERS (1 MILE), STOP IMMEDIATELY, SWITCH OFF THE ENGINE
AND LOOK FOR OTHER POSSIBLE CAUSES.
2
3
– THE COOLING FAN ON THE RADIATOR IS NOT WORKING:
THE COOLING FAN MUST BE RUNNING, WHEN THE COOLING LIQUID TEMPER-
ATURE IS 120°C (248°F) AND THE IGNITION IS ON. IF THE FAN IS NOT WORK-
ING, AND THERE APPEARS TO BE SUFFICIENT COOLING LIQUID, THE ONLY
THING YOU CAN DO IS TO DRIVE ON TO YOUR NEAREST AUTHORIZED KTM
WORKSHOP AT THE LEAST POSSIBLE ENGINE LOAD.
36
– TOO LITTLE COOLING LIQUID IN THE SYSTEM:
CHECK WHETHER ANY COOLING LIQUID IS LEAKING OUT (ALSO ON THE BOT-
TOM OF THE MOTORCYCLE).
LET THE ENGINE COOL DOWN AND CHECK THE COOLING LIQUID LEVEL IN
THE RADIATOR (SEE CHAPTER CHECKING THE COOLING LIQUID LEVEL IN THE
RADIATOR). ONLY CONTINUE TO DRIVE IF THERE IS ENOUGH COOLING LIQ-
UID IN THE SYSTEM. CONTACT AN AUTHORIZED KTM WORKSHOP TO HAVE
THE ERROR ELIMINATED. YOU WILL DAMAGE THE ENGINE IF YOU CONTINUE
TO DRIVE WHEN THE COOLING LIQUID TEMPERATURE WARNING LAMP IS ON.
– EXCESSIVE USE OF THE CLUTCH AT SLOW SPEED
4
A mixture of 50% antifreeze and 50% distilled water is used as the cooling
liquid. How-ever, the anti-freeze protection must be at least -25° C
(-13° F). Aside from antifreezing protection, this mixture also provides great
corrosion protection which is why it must not be replaced by pure water.
– FOR THE COOLING SYSTEM, USE ONLY HIGH-GRADE ANTIFREEZER (MOTOREX
ANTI-FREEZE). USING LOWERGRADE ANTIFREEZE AGENTS, CAN CAUSE COR-
ROSION AND COOLANT FOAMING.
– MORE ANTIFREEZE MUST BE ADDED IF YOU PLAN TO TRAVEL TO A REGION
WHERE TEMPERATURES ARE EXPECTED TO DROP BELOW -25°C (-13°F).
Pressure induced by heating of the cooling liquid in the cooling system is con-
trolled by a valve in the radiator cap [4]; a water temperature rising up to 125°
C (257° F) is admissible, without fear of problems.
Any excess cooling liquid caused by thermal expansion is conducted to the
compensating tank [5]. It will be sucked back in as soon as the temperature
in the cooling system drops.
5
Checking the cooling liquid level in the compensating tank
Check the level of the cooling liquid when the engine is cold. It should fall
between the MIN and MAX marks on the compensating tank [6].
Add cooling liquid (see above for mixture ratio) if the cooling liquid level drops
below the MIN mark.
If you need to add cooling liquid quite often, the cooling system may leak. If
the compensating tank is empty, also check the cooling liquid level in the
radiator. Have the cooling system checked by an authorized KTM
workshop.

Checking the cooling liquid level in the radiator *
Hold the radiator cap [1] with a cloth, carefully turn in a counterclockwise
direction and remove. The radiator should be completely filled with cooling
liquid; no air should be in the radiator.
If any cooling liquid is missing, the cooling system is probably leaking. Have
the cooling system checked at an authorized KTM workshop.
1
IF POSSIBLE, CHECK THE COOLING LIQUID LEVEL WHEN THE ENGINE IS COLD.
IF YOU NEED TO REMOVE THE RADIATOR CAP WHEN THE ENGINE IS HOT, HOLD
THE CAP WITH A CLOTH AND OPEN SLOWLY, ALLOWING ANY EXCESS PRESSURE
TO ESCAPE (DANGER OF SCALDING).
IF MORE THAN 1 LITER OF COOLING LIQUID NEEDS TO BE ADDED, YOU WILL NEED
TO BLEED THE COOLING SYSTEM.
2
2
Bleeding the cooling system *
Take off the left and right spoilers. To take off the spoilers, remove the screws
[2] and [3] on each side.
3
3
37
Remove the bleeder screw [4] on the left side of the radiator.
4
To completely bleed the cooling system, the motorcycle must be raised approx.
50 cm in the front.
Add cooling liquid until it runs out of the vent holes without bubbles and imme-
diately mount the screw to prevent air from entering the radiator.
Completely fill the radiator with cooling liquid. Mount the radiator cap and
move the motorcycle into a horizontal position again. Now fill the compen-
sating tank [5] with cooling liquid until it reaches a level between the MIN
and MAX marks. Close the compensating tank and mount both spoilers.

Changing the basic position of the clutch lever
The basic position of the clutch lever can be modified by turning the adjust-
ing screw [1]. This lets you adjust the best clutch lever position for any hand
size.
To adjust, pull the clutch lever towards the front. Turning the adjusting screw
in a clockwise direction will move the clutch lever away from the driver.
Turning the adjusting screw in a counterclockwise direction will move the clutch
lever towards the driver.
ADJUSTMENT OF THE CLUTCH LEVER POSITION IS ONLY POSSIBLE WITHIN CER-
TAIN LIMITS. ONLY TURN THE ADJUSTING SCREW MANUALLY AND NEVER APPLY
EXCESSIVE FORCE.
1
Checking the oil level of the hydraulic clutch
The oil level should be between the "MIN" and "MAX" marks with the master
cylinder in a horizontal position.
If necessary, add SAE 10 biodegradable hydraulic oil (Motorex clutch fluid
75), available from your authorized KTM workshop.
KTM USES BIODEGRADABLE, HYDRAULIC MINERAL OIL TO ACTUATE THE HYDRAULIC
CLUTCH. DO NOT MIX THIS OIL WITH ANY OTHER HYDRAULIC OIL. ALWAYS USE
ORIGINAL KTM HYDRAULIC OIL (AVAILABLE FROM YOUR AUTHORIZED KTM WORK-
SHOP) TO MAKE SURE YOUR CLUTCH OPERATES SMOOTHLY.
NEVER REFILL WITH BRAKE FLUID.
38
Adjusting the handlebar tilt
Loosen the screws [2]. Adjust the handlebar and tighten the screws to 20 Nm.
Make sure the handlebar instruments do not touch the fuel tank when the
handlebar is completely turned.
2
TILTING THE HANDLEBAR TOO FAR BACK WILL REDUCE THE STEERING ANGLE
SINCE THE HANDLEBAR INSTRUMENTS WILL TOUCH THE FUEL TANK
IF THE HANDLEBAR IS TILTED TOO FAR BACK, THE HANDLEBAR INSTRUMENTS
MAY DAMAGE THE FUEL TANK
2
Checking and adjusting the throttle cable play *
When starting to turn the throttle grip, you should feel an initial backlash of
3-5 mm (0.12-0.2 in).
To adjust, loosen the counter nut [3], turn the adjusting screw [4] as needed
and tighten the counter nut again.
Make sure that the throttle grip will return to the idle position automatically
once you let go of it.
To check the correctness of this setting, start the engine, turn the handlebar
left and right, in both cases as far as it will go. This must not cause any changes
in idling speed. Otherwise, you have to increase the backlash of the throttle
cable.

Engine oil
Automobile engine oil used to be used for four-stroke motorcycles before there
were separate motorcycle specifications. Different technical developments made
it necessary to have a separate specification for four-stroke motorcycles - the
JASO T903 MA standard. Whereas car engines require long changing inter-
vals, motorcycle engines require a higher power output at higher speeds. Most
motorcycle engines also use the same oil to lubricate the transmission and
the clutch. The JASO MA standard responds to these special requirements.
Only use fully synthetic engine oils that meet the JASO MA quality require-
ments (see information on the can).
JASO T903 MA
TEMPERATURE
0°C
32°F
KTM recommends Motorex Power Synt 4T in the 10W/50 viscosity (for tem-
peratures over 0°C, 32°F) or 5W/40 (for temperatures under 0°C, 32°F).
5W/40
10W/50
Checking the engine oil level
Check the engine oil level when the engine is warm (at least 4 bars on the
temperature indicator light up). Allow the warm engine to run idle for approx.
1 minute and place the motorcycle on a level surface (not on the side stand).
Wait 20 seconds to allow the oil level in the inspection glass to adjust to the
oil level in the oil tank. The oil level should be between the MIN and MAX
marks, add engine oil if necessary.
ALWAYS CHECK THE OIL LEVEL WHEN THE ENGINE IS WARM. A COLD ENGINE
CAN DISTORT THE MEASURING RESULTS. ENGINE OIL EXPANDS WHEN HEATED,
INCREASING THE OIL LEVEL.
39
Refilling engine oil
To refill engine oil, take off the right spoiler [1] by removing the screws [2].
1
2
2
Also remove the screws [3] and take off the spoiler.
3
3
Unscrew the plug [4] and refill engine oil. Wait 20 seconds and check the oil
level again. The quantity of oil between the MIN and MAX marks is 0.3 liter.
Mount the plug and check the engine for leaks.
Finally, mount the spoilers.

Changing the engine oil and the oil filter, cleaning the oil screen *
NOTE: The LC8 engine has a dry-sump lubrication system. The engine oil is
pumped from the oil sump in the engine case to the oil tank. The engine oil
must also be drained from the oil tank during an oil change. Since many parts
must be demounted for an oil change, we recommend having the engine oil
changed by an authorized KTM workshop.
During the guaranty period, the oil change must be performed by an author-
ized KTM mechanic. Otherwise, the guarantee will become void.
The engine oil change is to be carried out when the engine is still warm.

CLEANING »
Regular cleansing and paintwork care are part of the maintenance work and help to maintain the value of your motorcycle.
NEVER CLEAN THE MOTORCYCLE WITH A POWER WASHER OR A STRONG WATER JET, OTHERWISE THE PRESSURE WILL ALLOW WATER TO
ENTER THE ELECTRIC COMPONENTS, PLUGS, CABLES, BEARINGS, ETC. WHICH CAN CAUSE MALFUNCTIONING OR CAN LEAD TO PREMATURE
WEAR OF THESE COMPONENTS.
– Before you wash your motorcycle, close the muffler openings.
– Use warm water with a commercial detergent and sponge. Coarse dirt can be removed with a soft water jet. Areas that are heavily
soiled can be sprayed with a motorcycle cleaner (e.g. Motorex 900) and cleaned with a 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. Due to the heat, the water also evaporates at the
unapproachable parts of the engine and the brakes.
– After the motorcycle has cooled down, oil or lubricate all of the friction bearings and bearing positions and treat the chain with
chain spray. Treat all bare areas (except brake disks) with a corrosion inhibitor (e.g. Motorex Protect & Shine).
– The exhaust pipes can be polished with a chrome care product. The mufflers are made of stainless steel and should be treated with
a suitable care product.
– To prevent failures in the electric system, you should treat the ignition lock, the emergency OFF switch, light switch and the socket
connectors with contact spray.
– Treat all of the painted parts with a mild paint care product (e.g. Motorex Moto Polish).
45
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
precautions against the aggressive road salt.
– clean motorcycle thoroughly and let it dry
– treat engine, swing arm, and all other bare parts (except for brake discs) with a wax-based anti-corrosion agent.
KEEP ANTI-CORROSION AGENT FROM GETTING INTO CONTACT WITH THE BRAKE DISCS, FOR 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 »
If you plan to immobilize your motorcycle for a longer period of time, proceed as follows:
– Run the tank empty to be able to add fresh fuel when starting up again.
– Clean the motorcycle thoroughly (see CLEANING chapter).
– Change the engine oil and the oil filter (old engine oil contains aggressive impurities).
– Check the quantity of antifreeze and cooling liquid.
– Remove and charge the battery (see Charging the battery chapter).
– If possible, jack up the motorcycle to lift the wheels off the ground.
– The storage site should be dry and not subject to larger temperature fluctuations.
– Cover the motorcycle with a permeable cover or blanket. Do not use impermeable material since it will not allow and moisture to
escape and will cause corrosion.
DO NOT BRIEFLY RUN THE ENGINE OF AN IMMOBILIZED MOTORCYCLE SINCE THE ENGINE WILL NOT BECOME WARM ENOUGH AND ANY VAPOR
PRODUCED DURING THE COMBUSTION PROCESS WILL CONDENSE AND CAUSE THE VALVES AND EXHAUST TO RUST.
STARTING UP AFTER IMMOBILIZATION
– Mount the charged battery (pay attention to the polarity).
– Fill fresh fuel in the tank.
– Inspect the motorcycle as you would before each start-up (see "Driving Instructions").
– Go on a short, cautious test ride
NOTE: before you store your motorcycle at the end of the season, check all parts for proper functioning and wear. If service, repairs or
conversions are necessary, have them carried out while the motorcycle is immobilized (workshops are not fully utilized). This will help
to avoid long waiting periods at the beginning of the season.
