JASO T903 MA2
Different technical development directions required a separate specification for motorcycles
–
the JASO T903 MA2 stan-
dard.
Earlier, engine oils from the automobile industry were used for motorcycles because there was no separate motorcycle
specification.
Whereas long service intervals are demanded for automobile engines, the focus for motorcycle engines is on high perfor-
mance 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.
JASO FD
JASO FD is a classification for a 2-stroke engine oil that was specifically developed for the extreme demands of racing.
Thanks to first-rate synthetic esters and specially designed additives, superb combustion is achieved even under extreme
operating conditions.
