KTM 2016 RC 390 User Manual

26 STANDARDS 189
JASO T903 MA
Different technical development directions required a new specification for 4-stroke motorcycles – the JASO T903 MA Standard. Ear-
lier, engine oils from the automobile industry were used for 4-stroke motorcycles because there was no separate motorcycle specification.
Whereas long service intervals are demanded for automobile engines, high performance at high engine speeds are in the foreground for
motorcycle engines. In most motorcycles, the gearbox and the clutch are lubricated with the same oil as the engine. The JASO MA Stan-
dard meets these special requirements.
SAE
The SAE viscosity classes were defined by the Society of Automotive Engineers and are used for classifying oils according to their viscos-
ity. The viscosity describes only one property of oil and says nothing about quality.
