From its experience with transmission pulleys, Baker Drivetrain realized that steel is the material of choice. (Aluminum pulley teeth never hold up with miles, get deformed creating saggy belts). Same with the clutch basket where steel is the choice material to avoid rattle noise created by aluminum deformed flanks as it can be experienced with some competitor products.
So, The Baker Softail Synchronous Belt Drive uses only stainless steel pulleys with of course the exception of the motor plate and edge guard made of 6061_T6 plate stock and the optional “Dog bone” bearing support made of 6061-T6 forgings. Belt is 2.4″ and the belt system is provided with an “at-rattle” hardware designed for silent operation when stopped idling with the clutch disengaged. Available in show polish or black anodizing with 0″ or 1/2″ offset configurations. Baker Drivetrain.
