MUELLE INTERNO VARIADOR BULON POLINI D.35

Maxi-Speed variators from Polini enable the resistance and performance of this transmission component to be optimised due to the 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 variator assembly made from steel, is nickel-chrome treated for improved heat resistance.
