About Transmission & Drivetrain

Motorcycle transmission and drivetrain parts: clutch parts, chains and sprockets, primary drives, gearbox parts and bearings. Drivetrain parts depend on the model and year, so start with the Ride Finder.

Clutch Parts & Kits and Final & Primary Drive Parts & Kits are the parts that wear first. Brands include JT Sprockets, Barnett, Vortex, Drag Specialties and Belt Drives.

Gearbox & Transmission Parts, Gearboxes & Transmissions and Bearings are for transmission work. The rest of the drivetrain categories are listed above.

Replace a chain and both sprockets together, since a new chain wears quickly on a worn sprocket.
