Polini Piston d=60mm Vespa ET4 125cc AC

A complete kit that includes a piston (d.60mm), rings, gaskets, pin, and clips. As the piston is lighter and has an optimized design, you get about 10% more performance. There is no need to modify the cylinder; just change the piston and you're done. Quality made in Italy.

NOTE! Cannot be installed on models equipped with the L.E.A.D.E.R. engine!
