Polini Polini brings new life to Piaggio's 4T single-cylinder engines
Maximizing performance in urban scooters finds in this Polini kit a solution that is as effective as it is simple
Polini is an absolute benchmark when it comes to performance-enhancing components for scooter engines. This time, we're showing you the Ø61 cylinder specially developed for Piaggio 125 cc and 150 cc engines.
These are engines with 4-valve distribution and electronic fuel injection. Regarding regulations, both in Euro 4 and Euro 5 versions. An Italian duo, Polini and Piaggio, of infinite prestige.

With this kit, the displacement increases to 10.48 cu. in. (171.8 cc), a boost that results in an immediate 40% gain in acceleration. Pay attention to which motorcycle license you have.
This isn't a minor figure. That improvement in throttle response completely transforms the scooter's behavior in the city. As those of us who drive in urban areas know, this also means greater safety.
It allows every start from a standstill or every overtaking maneuver in heavy traffic to be handled with more vigor and less effort.
Polini kit full of technology
The cylinder is made of aluminum with an internal cast iron liner. It combines structural lightness and thermal resistance, which makes it ideal for intensive use.
The piston, also made of aluminum, features specific rings. The top ring is chrome-plated and adds a lower oil scraper ring made of steel. Both have been designed to maximize sealing and minimize wear during prolonged use.
However, to extract the kit's full potential, it's essential to install the ECU developed specifically for this configuration. Without this component, the overall performance would be limited by the original electronic management.

Available under reference 140.0238 and with a price of 299 euros plus VAT, this kit is also a product entirely manufactured in Italy.
It stands as a way to keep alive that tradition of precision engineering that has always distinguished Polini. This company continues to make a difference when it comes to getting the most out of the most popular urban engines.
