    Zipper’s is the source for the Bisagno Bros. billet 5 speed Big Twin transmission door! This heavy-duty door originally designed by Frank and John Bisagno is now being produced by Zipper’s. Its main features are the double-row ball bearings used to support the main and countershafts. Stock single-row bearings allow the shafts to flex considerably, causing accelerated wear on the gears and frictional power losses. This door holds the shafts straight and true for much needed additional support. Shifting is improved and more precise. Supplied show polished with spacers and shaft nuts for assembly. Beautiful polished finish, Made in USA!

    One of the less desirable byproducts of increased power is the need for a clutch spring upgrade, and the additional lever effort it requires. By adding the Variable Pressure Clutch (VPC) devise, clutch plate holding pressure is reduced at lower RPM’s, and increased as RPM rises, reducing the chance of clutch slippage as power builds. the VPC system reduces initial pressure and uses weights and centrifugal force to increase pressure as RPM builds. Clutch lever effort is reduced up to 50% at idle and low RPM, resulting in less hand fatigue, smoother engagement and easy neutral location.
