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 intervals, 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
requirements (see information 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
The engine oil level can be checked when the engine is cold or warm.
To check, place the motorcycle in an upright position on a level surface
(center stand).
If the engine is cold, the oil level should be visible at the lower edge
A
of
the inspection glass.
If the engine is warm, the oil level should be visible at the upper edge
B
of
the inspection glass.
Add engine oil if necessary.
