Product description

The piston set is an essential part of the engine group and ensures reliable power transmission in the combustion process. The use of high-quality materials and precise manufacturing ensure a long service life and consistent performance. The moly coating on the piston skirt reduces friction and wear, which is particularly advantageous for sporting use.

The nitride-coated steel rings ensure a good seal in the cylinder and help optimize the compression ratio. The standard size C of the piston is matched to the original dimensions of the Yamaha WR 125, ensuring easy installation and compatibility.

This piston set kit is intended for use in the Yamaha WR 125 2-stroke engine and is suitable for repair work or replacing worn components. The combination of cast pistons and high-quality rings supports stable engine performance and improved durability.
