JASO T903 MA2
Different technical development directions required a separate specification for motorcycles – the JASO T903 MA2
standard.
Earlier, engine oils from the automobile industry were used for motorcycles because there was no separate motor-
cycle specification.
Whereas long service intervals are demanded for automobile engines, the focus for motorcycle engines is on high
performance at high engine speeds.
In most motorcycle engines, the transmission and clutch are lubricated with the same oil.
The JASO T903 MA2 standard 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 viscosity. The viscosity describes only one property of oil and says nothing about quality.
