Engine oil
Automobile engine oil used to be used for four-stroke motorcycles before there
were separate 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 inter-
vals, motorcycle engines require a higher power output at higher speeds. Most
motorcycle engines also use the same oil to lubricate the transmission and
the clutch. The JASO MA standard responds to these special requirements.
Only use fully synthetic engine oils that meet the JASO MA quality require-
ments (see information on the can).
KTM recommends Motorex Power Synt 4T in the 10W/50 viscosity (for tem-
peratures 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 indicator light up). Allow the warm engine to run idle for approx.
1 minute and place the motorcycle on a level surface (not on the side stand).
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 MEASURING RESULTS. ENGINE OIL EXPANDS WHEN HEATED,
INCREASING THE OIL LEVEL.
Refilling engine oil
To refill engine oil, take off the right spoiler [1] by removing the screws [2].
Also remove the screws [3] and take off the spoiler.
Unscrew the plug [4] and refill engine oil. Wait 20 seconds and check the oil
level again. The quantity of oil between the MIN and MAX marks is 0.3 liter.
Mount the plug and check the engine for leaks.
Finally, mount the spoilers.
– INSUFFICIENT AMOUNTS OF OR LOW-GRADE ENGINE OIL LEAD TO PREMA-
TURE WEAR IN THE ENGINE.
– DO NOT OVERFILL THE ENGINE CASE.
– DO NOT UNDERFILL THE ENGINE CASE.
