The WISECO RE826M07900 piston kit is engineered to deliver reliable, dyno-proven power gains for Honda CRF250R and RX models. Crafted with precision, this 79.00 mm piston features an asymmetric skirt design that promotes even wear and load distribution on the major thrust skirt, enhancing durability and performance during demanding riding conditions. Made from 100% billet aluminum, the piston offers a superior strength-to-weight ratio, ensuring longevity and robust operation. The high compression ratio of 14:1 (for 450cc) and 14.5:1 (for 250cc) maximizes torque and throttle response, providing a noticeable improvement in engine responsiveness. The dome-shaped combustion chamber enhances flame travel, promoting more complete and efficient air/fuel burn, which translates into increased power output and fuel efficiency. The precision-fit ring and custom-lapped compression ring ensure optimal sealing, further boosting engine performance while reducing blow-by.
The piston features a DLC-coated pin that minimizes friction and resists scuffing, while enhanced pin oiling channels improve lubrication and reduce wear. The pressure seal groove is designed to prevent ring lifting and power loss, ensuring consistent compression. The ArmorGlide® skirt coating reduces friction and noise, offering quieter operation and improved scuff resistance. Each piston kit includes rings, pin, and circlips, ready for installation. Manufactured in the USA, this piston kit combines advanced engineering with high-quality materials to meet the demands of serious riders and racers alike.
