The WISECO RE804M07800 piston kit is engineered to deliver dyno-proven power enhancements for high-performance motorcycle applications. Crafted with precision, this piston features an asymmetric skirt design that ensures improved wear characteristics and even load distribution on the major thrust skirt, contributing to longer engine life and consistent performance. The kit includes a custom-lapped compression ring that enhances sealing efficiency, resulting in increased power output and optimal combustion. Made from 100% billet machined aluminum, the piston offers an exceptional strength-to-weight ratio, ensuring durability without adding unnecessary weight to the engine.
The high compression ratios of 14:1 for 450cc and 14.5:1 for 250cc models maximize torque and throttle response, making it ideal for aggressive riding and racing scenarios. The dome-shaped combustion chamber design improves flame travel, promoting more efficient air/fuel mixture combustion and improving overall engine efficiency. The piston features a DLC-coated piston pin that reduces friction, minimizes scuffing, and extends component lifespan. Enhanced pin oiling channels ensure superior lubrication, further reducing wear and friction during operation.
Additional features include a pressure seal groove that reduces ring lifting, minimizing power loss, and the ArmorGlide® skirt coating that significantly decreases friction for quieter operation and improved scuff resistance. This comprehensive piston kit includes rings, pin, and circlips, providing everything needed for installation. Proudly made in the USA, the WISECO piston kit is designed for riders seeking reliable performance and durability in demanding riding conditions.
