Refresh your 2-stroke top end with a VERTEX cast replica piston kit built for fast break-in and long service life. Heat-treated and moly-coated for reduced friction and reliable performance.
Bring your 2-stroke back to crisp, reliable power with the VERTEX Top End Piston Kit. This cast OE-replacement (replica) piston is designed to restore compression and performance after hours of riding, making it an ideal choice for routine top-end service or a preventative rebuild.
Thanks to a T-5 heat-treat hardening/tempering cycle and a high-tech molybdenum disulphite (MoS2) skirt coating, the piston is built to break in faster, reduce friction, and help extend piston life—especially important in high-revving 2-stroke engines where heat and wear are constant challenges.
