Product description

The piston set is designed as a kit and contains all the necessary components for replacement in the engine of the Yamaha WR 125. The forged aluminum alloy ensures high strength and low weight. The molybdenum disulfide coating on the piston skirt reduces wear and improves sliding in the cylinder barrel.

The piston rings are made of cast steel and have a nitride coating that ensures improved wear resistance and sealing performance. The standard size C with a piston diameter of 53.95 mm fits exactly to the bore of 54.00 mm and ensures an optimal fit.

The compression ratio corresponds to the original condition, which enables easy integration without adjustments. The use of the piston set supports reliable engine performance and a long service life of the 2-stroke engine.

Summary

• High-quality, forged race piston for Yamaha WR 125
• Reduced friction thanks to molybdenum disulfide coating
• Perfectly fitting standard size for 54mm bore
• Delivered as a complete piston and ring set
• Suitable for the 2-stroke engine with 125 cc displacement
