Polini Cylinder Kit cast iron 50mm Vespa PK / XL / APE 50cc, cast iron cylinder with 50mm bore by Polini.
This 68mm diameter cylinder will raise displacement to a total of 84cc while allowing to retain the original crankshaft, and increased displacement leads to higher top speed. Port timings are designed for racing, with an impressive boost in torque throughout the entire rpm range.
The cylinder has 6 transfer ports and boost ports. The piston is a 2-ring piston with low-friction coating.
This extremely reliable cylinder will boost torque and overall performance and is suitable for original or close to original engine set-ups. And, made by Polini, everything is manufactured according to very high quality standards. Optimum RPM range is approximately 7,700rpm.
Always make sure that other engine components like crankshaft, bearings and manifolds are in top shape, otherwise performance, even with a powerful cylinder, might suffer.
