Polini is one of the big names in 50cc scooter tuning, and is also one of the leading manufacturers of tuning parts for Vespa, modern and vintage. Cylinders, intake manifolds, exhausts, air filters, carburetors, crankshafts and more - everything you need to boost the performance of your Classic Vespa.

Polini Cylinder Kit cast iron 61mm Vespa 125cc T5, cast iron cylinder with 61mm bore by Polini.

This 61mm diameter cylinder will raise displacement to a total of 152cc 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 7,500rpm. 16.5hp can be easily achieved.

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.
