Abstract
A driveshaft assembly for a motorcycle supercharger includes: an elongated driveshaft defining a tapered distal portion, and a flywheel drive pulley defining a tapered central bore. The tapered central bore of the drive pulley is configured to receive the tapered distal portion of the driveshaft to form a locking-taper interface between the driveshaft and the flywheel drive pulley, thereby substantially increasing the durability and longevity of the supercharger. The enhanced driveshaft assembly may be retro-fitted onto an existing supercharger system, or may be part of a new or custom supercharger installation.
