Piston, Polini 210 cc - 68.4 mm (Rally, P/PX 200), Single Ring Type for Scooters & Mopeds

Polini 210 Cc Piston for Rally and P/PX 200 Scooters

This piston is made for the Polini 210 cc kit and is intended for Rally and P/PX 200 scooters. The package comes with the rings, a wrist pin, and circlips. As with many vintage Vespa scooter parts, it is a direct swap for the original and needs no modification. You will typically need a replacement when power falls off because worn rings are no longer sealing well, which can lead to oil burning and smoke.

When to Replace It

Consider replacing this piston if you see heavy smoke or notice the engine has lost power. Worn piston rings can let oil pass and reduce compression, which affects how well the scooter runs.
