Description
Stage6 Piston Rings Racing 72cc, 47mm, GY6 50cc 4-stroke, spare piston rings for Stage6's 72cc 4-stroke cylinder for GY6 50cc.
Piston rings should be replaced on a regular basis. You can check the piston ring groove for clearance and wear, and if necessary replace the ring(s). Worn out or damaged piston rings cause the bike to lose power, produce more smoke, and will cause the jetting to appear rich. In some cases it is sufficient to simply replace the ring(s) instead of the entire piston
We recommend to slightly lubricate ring and piston before reassembling the cylinder.

Piston rings are sealing elements. They are inserted into the grooves of the piston to ensure sealing between the piston and the cylinder wall. Piston rings vary in size and shape and can be chrome-plated or cast iron, depending on the type of cylinder.
2-stroke piston Ring
The upper ring (often chrome-plated) is fireproof and seals the combustion chamber. The lower ring provides lubrication to the cylinder liner. 1-ring pistons perform both functions, but this results in a shorter service life.
4-stroke piston Rings
The upper ring also has the function of sealing the combustion chamber, while the middle ring collects excess oil and contributes to engine compression. The lower ring, known as the oil scraper ring, prevents engine oil from entering the combustion chamber.
Piston rings play a crucial role in the proper functioning and service life of the cylinder, whether on a motorcycle, scooter or moped.
