Polini crankshaft and cylinder kit for Polini for Piaggio Ciao and Si


Polini Motori goes on with the latest news dedicated to the legendary Piaggio Ciao and Si.
Polini Motori continues to work to enrich the line of products dedicated to Piaggio Ciao and Si. After the Polini For Race reed crankcase and the CDI, the factory presents two other innovations studied and designed as usual with the aim of increasing performance and resistance, especially for the reed engines, born with limitations given by the original housing.
The new Polini Ø 47 cast iron cylinder kit with 4 studs has been designed for a specific combination with the Polini For Race crankcase for all Ciao, Si, Bravo, Boss, Grillo mopeds.
The drilling involves the fixing of the cylinder by means of 4 studs that ensure a more efficient distribution of the stresses during operation and allow a centered discharge with the axis along which the washing process develops and a thin crossbar.
Further technical features: exhaust transfer with booster holes, one piston ring, head gasket in annealed aluminum. All these are important details that guarantee better performance.
For the assembly of the cylinder kit it is necessary to match the specific exhaust available at the end of 2023.
