There's no comparison to BAKER Drivetrain products. Our firm commitment to quality American-made parts—designed and built by the people who ride them—delivers an uncompromising product that lasts.
Improve the performance of your American V-Twin Harley-Davidson®
BAKER Drivetrain was started in 1998 because engines were making more power, but nobody was taking the drivetrain seriously. Choose the right drivetrain, chassis, and rear wheel to put the power to the ground.
All BAKER aftermarket motorcycle parts are designed and manufactured right here in America. BAKER Drivetrain continues to introduce new solutions based on empirically-based inspiration as they ride their American V-Twins and get ideas from their American riding buddies using their proven engineering methodologies.
The components for the Harley-Davidson® drivetrain aftermarket we offer are broken up into 4 catalogs: Cruise Drive era (2007-later), 5-speed era (1984-2006), 4-speed era (1936-86), and Custom/Performance (includes Big Dog and Sportster/Buell).
