Polini hi-speed variator kits enable the resistance and performance of this transmission component to be optimised due to several technical specifications specific to the brand. Polini torque springs are 30% harder than the original fit, and thanks to a specific variator body, internal lubrication is continuous. This hi-speed variator kit is supplied with its own belt and fixed half-pulley.
