Polini Cylinder d.43mm for Gilera GSA / Vespino ALX / F9 / Velofax

Polini Cylinder d.43mm for Gilera GSA / Vespino ALX / F9 / Velofax.

If you are looking to upgrade the motorcycle, this cylinder increases displacement to 65 cc, providing greater strength and pull at low and mid-range revs, resulting in power throughout the RPM range with a higher top speed.

To achieve maximum performance, we recommend replacing the carburetor with one of a larger diameter, as well as installing a sport-range exhaust to improve gas evacuation. It is also advisable to check the condition of the crankshaft and fit a cold heat-range spark plug to ensure the engine’s thermal stability under the new operating demands.
