DRIVING INSTRUCTIONS
»
Driving
The engine speed, and thus the driving speed, are regulated by
the throttle grip.
The choke must always be deactivated as soon as the engine has
warmed up.
– After falling with the motorcycle, check all its functions thor-
oughly before using it again.
– A bent handlebar must always be replaced. Never try to
straighten the handlebar because this will cause it to lose its
stability.
– Driving a cold engine at high speed will reduce the life of the
engine. We recommend to warm the engine up at a medium
engine speed for several minutes before switching to full load.
– Never tilt the motorcycle over the side stand to warm up the
engine. The side stand could fold away and the motorcycle run
out of control.
– In the event that, while your child is riding on the motorcycle,
you notice any unusual operation-related noise, your child
should stop immediately, turn the engine off, and contact an
authorized KTM dealer.
Braking
Close the throttle and squeeze both brake levers simultaneously.
On sandy, wet or slippery terrain the rear wheel brake should be
preferred. The brakes should always be operated carefully as
locking wheels can cause skidding or falls.
– Brake drum and linings heat up during brake operation, thus
reducing the effect of the brakes.
– Wet brakes have reduced brake performance, therefore be sure
to brake them dry after cleaning.
– If the resistance of the hand brake lever feels unresponsive,
something is wrong with the brake system. Have the brake sys-
tem checked at a KTM workshop before you let your child drive
the motorcycle.
Stopping
Reduce the speed. Immediately before the motorcycle comes to
a stop, put the left foot down. To turn off the engine, press the
short circuit button until the engine stops. Close the fuel tap.
Motorcycles produce great heat during operation. Therefore, keep
in mind that the engine, the exhaust system and the brakes can
heat up considerably. Make sure that these parts are not touched
and always take care, when parking the motorcycle, that other per-
sons will not burn themselves.
– Close the fuel tap when leaving the motorcycle. Otherwise the
carburetor may get flooded and fuel will enter the engine.
– The side stand or plug-in stand is designed to hold the weight
of the motorcycle only. By sitting on the motorcycle, your child
will put additional weight on the side stand, possibly causing
the side stand or frame to be damaged or the motorcycle to
fall down.
Refueling, fuel
Oil (high-grade two-stroke engine oil) must be mixed with the fuel
(ROZ 95) at a mixing ratio of 1:60.
Fuel and engine oil should only be mixed immediately before
use.KTM recommends Motorex 2T Cross Power.
Gasoline is highly flammable and poisonous. Extreme caution
should be used when handling gasoline. Never refuel the motor-
cycle 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 swallowed or splashed in the eyes, seek a
doctor’s advice immediately.
– Only use premium-grade gasoline ROZ 95 mixed with high-
grade two-stroke engine oil. Other types of gasoline can cause
engine failure.
– Only use known brands of high-grade 2-stroke engine oil
(Motorex 2T Cross Power).
– Not enough oil or low-grade oil can cause erosion of the pis-
ton. when Using too much oil, the engine may start smoking
and foul the spark plug.
– Fuel expands when its temperature rises. Therefore do not fill
the tank to the top. (see fig.)
