IMPORTANT INFORMATION 5
Use definition
KTM sport motorcycles are designed and built to withstand the normal stresses and strains of competitive use. The motorcycles comply with currently valid regulations and categories of the top international motorsport organizations.
Info
The motorcycle must be used only in closed off areas remote from public road traffic.
Service
A prerequisite for perfect operation and prevention of wear is that the engine and chassis service, care and adjustment work described
in the owner's manual are properly carried out. Poor adjustment and tuning of the engine and chassis can lead to damage and breakage of components.
Using the motorcycle in difficult conditions such as on sand or very muddy or wet terrain can lead to above-average wear of components such as the transmission train or the brakes. For this reason, it may be necessary to service or replace worn parts before the
limit specified in the service schedule is reached.
Pay careful attention to the prescribed running-in period, inspection and service intervals. If you observe these exactly, you will ensure
a much longer service life for your motorcycle.
Warranty
The work prescribed in the service schedule must be carried out in an authorized KTM workshop only and confirmed in the customer's
service record and in the KTM dealer.net since otherwise no warranty claims will be honored. No warranty claims can be honored for
damage resulting from manipulations and/or alterations to the vehicle.
Fuel, oils, etc.
You should use the fuels, oils and greases according to specifications as listed in the owner's manual.
Spare parts, accessories
For your own safety, only use spare parts and accessory products that have been approved and/or recommended by KTM and have
them installed by an authorized KTM workshop. KTM accepts no liability for other products and any resulting damage or loss.
Certain spare parts and accessories are specified in parentheses in the descriptions. Your KTM dealer will be glad to advise you.
The current KTM PowerParts for your vehicle can be found on the KTM website.
International KTM Website: http://www.ktm.com
Work rules
Special tools are needed for certain tasks. They are not included with the vehicle but can be ordered under the number in parentheses. Ex.: bearing puller (15112017000)
During assembly, non-reusable parts (e.g. self-locking screws and nuts, seals, seal rings, O-rings, pins, lock washers) must be replaced
by new parts.
If a thread locker is used for the screw connections (e.g. Loctite®), follow the specific manufacturer instructions regarding its use.
Parts that are to be reused after disassembly must be cleaned and checked for damage and wear. Change damaged or worn parts.
After repair and maintenance, ensure that the vehicle is roadworthy.
Transport
Note
Danger of damage The parked vehicle may roll away or fall over.
– Always place the vehicle on a firm and even surface.
Note
Fire hazard Some vehicle components become very hot when the vehicle is operated.
– Do not park the vehicle near flammable or explosive substances. Do not place objects on the vehicle while it is still warm from
being run. Always let the vehicle cool first.
– Switch off the engine.
– Use straps or other suitable devices to secure the motorcycle against accidents or falling over.

7.2Starting
Danger
Danger of poisoning Exhaust gases are poisonous and inhaling them may result in unconsciousness and/or death.
– When running the engine, always make sure there is sufficient ventilation, and do not start or run the engine in an enclosed
space without an effective exhaust extraction system.
Note
Engine failure High engine speeds in cold engines have a negative effect on the service life of the engine.
– Always warm up the engine at low engine speeds.
Info
If the motorcycle is unwilling to start, the cause can be old fuel in the float chamber. The flammable elements of the fuel
evaporate after a long time of standing.
If the float chamber is filled with fresh fuel, the engine starts immediately.
Engine has been out of use for more than 1 week
–
Empty the carburetor float chamber. x ( p. 63)
– Turn the knurled screw on the fuel tap all the way counterclockwise.
Fuel can flow from the fuel tank to the carburetor.
– Remove the motorcycle from the stand.
– Shift gear to neutral.
The engine is cold
– Push the choke lever down all the way.
– Forcefully step on the kickstarter, pushing it all the way down.
Info
Do not open the throttle.
RIDING INSTRUCTIONS 16
7.3Starting off
Info
The plug-in stand must be removed prior to riding.
– Pull the clutch lever, engage 1st gear, release the clutch lever slowly and simultaneously open the throttle carefully.
7.4Shifting, riding
Warning
Danger of accidents If you change down at high engine speed, the rear wheel can lock up.
– Do not change into a low gear at high engine speed. The engine races and the rear wheel can lock up.
Info
If you hear unusual noises while riding, stop immediately, switch off the engine and contact an authorized KTM workshop.
First gear is used for starting off or for steep inclines.
– When conditions allow (incline, road situation, etc.), your child can shift into a higher gear. To do so, release the throttle while
simultaneously pulling the clutch lever, shift into the next gear, release the clutch and open the throttle.
– If the choke function was activated, deactivate it after the engine has warmed up.
– When you reach maximum speed after fully opening the throttle, turn back the throttle to about ¾ of its range. The speed hardly
drops, but the fuel consumption falls considerably.
– Your child should always open the throttle only as much as the engine can handle – abruptly opening the throttle increases fuel
consumption.
– To shift down, brake and close the throttle at the same time.
– Pull the clutch lever and shift into a lower gear, release the clutch lever slowly and open the throttle or shift again.
– Your child should switch off the engine if he or she expects to be standing for a long time.
Guideline
≥ 2 min
– Your child should avoid frequent and extended slipping of the clutch. This heats the engine oil, the engine and the cooling system.
– Insist that your child ride with a low rpm instead of with a high rpm and a slipping clutch.
7.5Braking
Warning
Danger of accidents If you brake too hard, the wheels can lock.
– Adapt your braking to the traffic situation and the road conditions.
Warning
Danger of accidents Reduced braking efficiency caused by spongy pressure point of front or rear brake.
– Check the brake system and do not continue riding. (Your authorized KTM workshop will be glad to help.)
Warning
Danger of accidents Reduced braking efficiency due to wet or dirty brakes.
– Clean or dry dirty or wet brakes by riding and braking gently.
– On sandy, wet or slippery surfaces, use the rear brake.
– Braking should always be completed before you go into a bend. Your child should change down to a lower gear appropriate to the
road speed.
– Insist that your child take advantage of the braking action of the engine when riding on long downhills. To do so, shift back one or
two gears, but do not overrev the engine. Your child will need to apply the brakes far less often and the brakes are not overheated.

Fire hazard Fuel is highly flammable.
– Never refuel the vehicle near open flames or burning cigarettes, and always switch off the engine first. Be careful that no
fuel is spilt, especially on hot vehicle components. Clean up spilt fuel immediately.
– Fuel in the fuel tank expands when warm and can escape if the tank is overfilled. See the notes on refueling.
Warning
Danger of poisoning Fuel is poisonous and a health hazard.
– Avoid contact of the fuel with skin, eyes and clothing. Do not inhale fuel vapors. If fuel gets into your eyes, rinse imme-
diately with water and contact a doctor. Wash affected skin areas immediately with soap and water. If fuel is swallowed,
contact a doctor immediately. Change clothing that has come into contact with fuel.
Warning
Environmental hazard Improper handling of fuel is a danger to the environment.
– Do not allow fuel to get into the ground water, the ground, or the sewage system.
