Product description

The piston set is part of the Engine Group and is delivered as a complete set with pistons and rings. The use of a forged aluminum piston offers high strength and low weight. The molybdenum disulfide coating on the piston skirt ensures improved lubrication and reduces wear in the cylinder barrel.

The piston rings are made of steel with a nitride coating, which provides increased hardness and a better seal. The precisely coordinated standard size C ensures an optimal fit in the cylinder of the Yamaha WR 125 with a 54 mm bore.

This piston set is designed for use in 2-stroke engines and supports the engine's standard compression ratio. The combination of high-quality materials and precise manufacturing contributes to longevity and reliability.

The VERTEX piston set (Forged Race) is a suitable choice for replacing or servicing the piston on the Yamaha WR 125 and represents a technically sophisticated component.
