Polini piston Vespino ALX / F9 / Velofax d.43mm

Polini Piston Vespino ALX / F9 / Velofax d.43mm

The 43 mm Polini piston is designed as a replacement for Polini 65cc cylinders intended for 2-stroke Vespino engines.

Manufactured from aluminum alloy, this piston is designed to withstand the usual operating conditions of a two-stroke engine, while maintaining a proper fit within the compatible cylinder. Its replacement allows the internal component of the cylinder kit to be renewed when it shows wear or during the installation of a cylinder kit.

For correct installation, it is recommended to check compatibility with the cylinder, assembly clearance, the condition of the wrist pin, and the piston rings before assembling the engine.
