Product description

The VERTEX piston set is designed for use in the top end area of the engine. The use of a forged aluminum piston ensures high strength and improved heat dissipation. The molybdenum disulfide coating on the piston skirt reduces friction between the piston and cylinder bore, which contributes to a longer component life.

The piston rings are made of cast steel and have a nitride coating that increases wear resistance and ensures optimal sealing. The precise dimensions of the piston kit are standard B size and matched to the 54.00mm bore size to ensure optimal fit and performance.

This kit is suitable for replacement as part of maintenance or repair work on the engine of the Yamaha WR 125. It helps restore engine performance and contributes to the reliability of the vehicle.
