PROX Ø82 mm Piston Ring Set - Ref. 02.6342
Replace worn rings and restore the necessary sealing performance to your 4-stroke engine for reliable operation. This PROX ring set, designed for motocross use, fits Ø82 mm piston kits and helps restore compression between the piston and cylinder after disassembly or machining.
Rings are a critical wear component: their replacement is an integral part of engine maintenance after machining or high mileage. By opting for a new set, you limit compression leaks and oil in the combustion chamber, facilitating engine tuning and piston break-in. Before installation, check the bore and lateral play to ensure compliance with manufacturer tolerances.
Biker Tip: Maintain cleanliness and lubrication during installation, respect the clearances and break-in procedures to ensure the longevity of the piston/ring/cylinder assembly.
