Piston Ring 177 cc Kit (63.4 mm First Oversize) for Polini for Scooters & Mopeds

Oversize Piston Ring Set for Polini Scooters and Mopeds

This first oversize ring set is made for Polini kits used in scooters and mopeds. Good ring sealing keeps pressure inside the combustion chamber where it belongs. When rings wear out, you may see smoke, use more oil, and notice weaker engine output. This item is one of the essential scooter pistons & piston rings you need to keep your vehicle running well.

Signs It Needs Replacing

Consider replacing the piston rings if you see smoke or find yourself adding oil more often than before. Worn rings can reduce both power and fuel efficiency. A tight seal in the combustion chamber is necessary for the engine to work correctly.
