Description

The Wiseco GP Series Piston Kit is meticulously engineered to deliver exceptional durability and power output for your Yamaha YZ 125, specifically for models manufactured between 1997 and 2004. This high-performance piston kit is built for the demanding conditions of racing and aggressive riding, ensuring your engine can withstand intense, sustained high RPMs. Each Wiseco GP Series Piston Kit component is electra-coated on critical surfaces including the dome, ring groove, and pin bore.

Furthermore, the GP Series pistons are designed with less external machining, a feature that significantly improves bore sealing and contributes to increased compression, directly translating into more responsive power. The exclusive ArmorGlide® skirt coating further enhances performance by reducing friction and noise, unlocking additional horsepower potential for your Yamaha YZ 125 piston. Proudly engineered, forged, and machined in the USA, this kit reflects Wiseco's commitment to quality and precision, offering a reliable upgrade for your motorcycle engine.
