Before you choose
Verify the engine’s viscosity and performance requirements, including wet-clutch compatibility where needed. Engine, primary, and transmission compartments may specify different fluids.
Does one oil service every compartment?
Some motorcycles share lubricant between systems; others have separate engine, primary, and transmission requirements. Follow the service information for your motorcycle.
