Specifically designed for small 50 cc engines, this TECNIUM Ø40.5 mm piston ring set allows for the restoration of compression during a refurbishment. Suitable for PW50 and QR50 machines, it is aimed at riders and preparers who want to replace worn parts with a dedicated reference.
The rings are essential components for restoring the seal between the piston and cylinder after wear or machining. Easy to install during engine maintenance, they are suitable for targeted refurbishment without replacing the entire piston-cylinder assembly. Ideal for the weekend workshop or preparing a 50 cc bike for off-road use.
Be sure to check the condition of the piston and cylinder and to adhere to the clearances recommended by the manufacturer before installation. This TECNIUM set offers a simple and dedicated solution for replacing worn rings and restoring clean engine performance.
