The JASO specifications were developed by the Japanese Society of Automotive Engineers for motorcycle lubricants. They define the performance and behavior of oils in wet clutches and two-stroke or four-stroke engines.

MA

The JASO MA specification is suitable for four-stroke motorcycles with a wet clutch. It protects the engine and ensures its proper operation.

The API specifications were developed by the American Petroleum Institute, which evaluates the quality and performance of lubricants in gasoline and diesel engines, according to international performance standards.

SL

The API SL specification provides reliable engine protection as well as clean combustion in previous generation gasoline engines.
