JASO MA: Delivers the desired friction performance motorcycles need to prevent slippage in the wet clutch. JASO MB: Delivers to scooters friction performance via friction modifiers in order to provide fuel economy benefits.
Communicating these benefits and considerations to end users is also important-while JASO MA lubricants are in fact suitable for all applications, MB lubricants may induce clutch slippage in motorcycles and must only be used in scooters.
