JASO T903
The JASO T903 standard is an index to
select engine oils for 4-stroke motorcycle
and ATV engines. Motorcycle and ATV
engines lubricate clutch and transmission
gears with engine oil. JASO T903 specifies
performance requirements for motorcycle
and ATV clutches and transmissions.
There are two classes, MA and MB. The oil

Energy Conserving
Suzuki does not recommend the use of
"ENERGY CONSERVING" or "RESOURCE

which have an API classification of SH, SJ
or SL have an "ENERGY CONSERVING"

clutch performance.
