KTM 65 SX Motorcycle User Manual


 
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 have the throttle wide open when changing down to a
lower gear. The engine will overrev, damaging the valves. In addi-
tion, the rear wheel blocks 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 occasionally to ensure that
it is supplied with sufficient lubricant which is mixed in the
fuel.
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
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.
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 braking effect. The brakes must be
pulled until they are dry or clean.
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 indication that some-
thing is wrong with the brake system. Don’t ride your motorcy-
cle anymore without first having the brake system looked over
by a KTM dealer.
Stopping
Brake motorcycle and shift gears to idling. To switch off the engine,
depress short circuit switch until the engine stops. Close fuel tap.
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 pedes-
trians are not likely to touch it and get burned.
Close the fuel tap when leaving your vehicle. Otherwise the car-
buretor may get flooded and fuel will enter the engine.
The Plugin- Stand is only designed for the weight of the motor-
cycle. If you get on your motor-cycle and thus put additional
weight on the motorcycle, the Plugin- Stand or the frame can
be damaged or the motorcycle may fall on the side.
Refueling, fuel
Unleaded premium gasoline RON 95 mixed with high grade two
stroke oil. Mixture ratio 1:60. Fuel and engine oil should only be
mixed immediately before use.
KTM recommends Motorex Cross Power 2T.
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 (USA = Premium RON
91) 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
Cross Power 2T).
Do not use premixed two-stroke oils, oils for outboard engines
or normal engine oil to prepare the mixture.
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.)
