Performance Machine Contour Open Belt Drive Primary Transmission for Harley Davidson Softail, Chopper and Custom Motorcycle in Polished, Chrome and Black finish

The Performance Machine Contour Primary Belt Drive has several key features that make it superior to all other belt drive primaries. The First is weight, as it is 12 pounds lighter then stock and can help return the weight balance to wide wheel bikes that are forced to push the primary drive further off center. Being 2 full inches thinner than the OEM unit also help with the wide bikes and will not interfere with access to the forward controls. Inside the primary, a compensator motor sprocket reduces the impact on the system and allows the use of a narrow belt. Race style clutch springs activate Barnett clutch plates for a smooth operation and long life.
