Engine oil
Automobile engine oil used to be used for four-stroke motorcycles before there were sepa-
rate 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 intervals, motorcycle engines require a higher power out-
put at higher speeds. Most motorcycle engines also use the same oil to lubricate the trans-
mission and the clutch. The JASO MA standard responds to these special requirements.
Only use fully synthetic engine oils that meet the JASO MA quality requirements (see infor-
mation on the can).
KTM recommends Motorex Power Synt 4T in the 10W/50 viscosity (for temperatures over
0°C, 32°F) or 5W/40 (for temperatures under 0°C, 32°F).
Checking the engine oil level
Check the engine oil level when the engine is warm (at least 4 bars on the temperature indi-
cator light up). Allow the warm engine to run idle for approx. 1 minute and motorcycle place
the motorcycle on a level surface (not on the side stand).
Turn off the engine, unscrew the oil dipstick
[5]
and wipe off with a cloth.
Screw the oil dip-
stick all the way back in
and back out again.
The oil level should fall between the lower end of the oil dipstick (MIN) and the MAX mark.
The oil capacity between the MIN and MAX mark is 0.5 liters (0.13 USgal). Add more engine
oil if necessary and check the engine for leakage.
– Insufficient amounts of or low-grade engine oil lead to premature wear in the engine.
– Do not overfill the engine case.
– Do not underfill the engine case.
