STANDARDS STANDARDS JASO T903 MA Different technical development directions required a new specification for 4-stroke motorcycles – the JASO T903 MA Standard.Earlier, 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 and ATV engines.With most motorcycles and ATVs, the gearbox and the clutch are lubricated with the same oil as the engine.
