Polini Piston Ring (68.4 mm, Upper Dyke) for Scooters & Mopeds

Polini Upper Dyke Piston Ring for Scooters and Mopeds

This 68.4 mm Polini piston ring is made for scooter and moped engines. It suits newer 210 cc cylinder kits that use a two-ring setup. As a key engine component, it helps keep the engine running as it should, so it fits naturally alongside other scooter pistons & piston rings. When a ring wears down, you may notice smoke, higher oil use, and lower compression.

Role of This Part

Piston rings keep the combustion chamber sealed. That seal has a direct effect on how the engine performs. Once the rings wear out, the engine can develop several problems, and replacing them is often the fix.
