Pulley Air Speed Polini Evolution 3 Piaggio NRG \/ Runner

With the Evolution3, Polini has developed a completely new transmission series. Torque driver as well as outer half of the variator are nearly entirely made of aluminium, which makes them a lot lighter than their predecessors. Furthermore, Polini offers a version with ceramic coating that is intended to offer longer-lasting surface roughness and therefore good belt grip and stable transmission functions in the transmission.

Comes with a white plastic fan.
