The Multivar widens the speed band at which the power is applied to the rear wheel.
So not only is acceleration and pulling through better, but the final speed can also be easily improved. The Multivar is supplied with all the necessary parts for installation.
Please note that the crankshaft nut must be loosened for installation.
A special tool is required to fix the front half of the pulley (BU5430).
