Product description

The piston set is designed for use in the Yamaha WR 125 engine and offers a precise fit thanks to the standard size A. The piston skirt has a molybdenum disulfide coating that reduces frictional resistance and thus helps reduce wear. The piston rings are made of cast steel with a nitride coating, which improves durability and sealing performance.

By using forged aluminum as the material for the piston, high strength and low weight are achieved. This supports the performance of the engine and contributes to reliability. The race forged piston design is specifically tailored to the requirements of sporty driving without changing the standard compression ratio.

The set includes all the necessary components for replacing the piston and piston rings, allowing for a simple and complete repair. The combination of high-quality materials and precise manufacturing makes the piston set a suitable choice for preserving or maintaining the Yamaha WR 125 engine.
