Polini based this cylinder kit on their 70cc Cast Iron Sport kit and redesigned it to improve performance and give it more power. More specifically, Polini modified the cylinder's port timings (longer) and redesigned the shape of the exhaust port resulting in an increase of power up to 10/13hp (with a 17.5mm carburetor and a sports exhaust). The piston is also a modified as a special "Corsa" piston even though it remains a two-ring piston; 10mm piston pin.

How to Install a cylinder on a scooter, motorcycle or moped
