New 47mm race piston for Minarelli V1 Polini kits.
Drop in replacement piston. Features a chrome dykes ring and scallops above the wrist pin. Custom made just for us by our friends in Italy.
A nice and simple upgrade to the already proven Polini design.
Same piston crown as the original so your custom head should work just fine.
Replacement rings are here.
Comes with piston, pin, clips, and ring.
