GP Series Piston Kit

Push reliability and performance further with the WISECO GP Series Piston Kit. Designed for endurance and high-RPM use, this forged piston kit is engineered to handle demanding 2-stroke riding conditions while helping your engine run smoother and more efficiently. Advanced coatings reduce friction and wear, supporting consistent power and longer service life.

If you’re rebuilding a top end or refreshing a worn cylinder, this kit helps restore compression and improves durability where it matters most. The electra-coating on critical areas is designed to protect against micro-welding, galling and detonation, while the ArmorGlide® skirt coating lowers friction and noise—freeing up horsepower potential and improving feel under load.
