WISECO offers a Racer Elite Series forged piston kit designed for the Yamaha YZ 125 2-stroke engines (2005–2018), intended for motocross and competition use requiring power, responsiveness, and reliability. Made from high-quality forged aluminum alloy, it features ArmorPlating technology on the crown and critical areas, as well as a low-friction skirt coating that improves lubrication and reduces internal wear. This design optimizes ring sealing, improves power delivery, and ensures consistent performance even under extreme conditions. The kit is typically a complete, ready-to-install set and includes the piston, rings, piston pin, and retaining rings for a reliable top-end rebuild.
