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 place the motor-
cycle on a level surface (not on the side stand).
Switch off the engine and 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 measur-
ing results. Engine oil expands when heated, increasing the oil level.
