Product description

The piston set is part of the engine group and includes all the necessary components for replacement in the upper area of the engine. The use of a forged aluminum alloy ensures high strength and good thermal conductivity. 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, which ensures increased resistance to abrasion. The standard size C guarantees an exact fit for the 125cc engine of the Yamaha WR 125, supporting optimal combustion and engine performance.

This top-end piston set is designed for racing use and offers a balanced combination of durability and performance. The set enables precise engine revision and helps restore engine function.
