The WISECO RE817M09600 piston kit is engineered for high-performance Honda TRX450R and ER models, offering reliable power gains proven through dynamometer testing. Crafted with precision, this piston features an asymmetric skirt design that enhances wear resistance and ensures even load distribution on the major thrust skirt, extending component lifespan and maintaining optimal engine performance. The kit includes a custom-lapped compression ring and a precision-fit piston ring, both designed to improve sealing and maximize power output. Constructed entirely from 100% billet material, the piston provides an exceptional strength-to-weight ratio for durability without adding unnecessary weight, ensuring responsive throttle control and robust engine operation.
High compression ratios of 14:1 for 450cc and 14.5:1 for 250cc models are incorporated to deliver maximum torque and acceleration, making this piston ideal for demanding riding conditions. The dome-shaped design optimizes flame travel within the combustion chamber, promoting more efficient air/fuel burn and enhancing power output. The DLC-coated piston pin reduces friction and scuffing, while enhanced pin oiling ensures superior lubrication and longevity. The pressure seal groove minimizes ring lifting, maintaining consistent compression and reducing power loss. Additionally, the ArmorGlide® skirt coating offers friction reduction for quieter operation and improved scuff resistance, contributing to the engine's overall reliability. This piston kit includes rings, pin, and circlips, simplifying installation and ensuring compatibility. Proudly made in the USA, the WISECO RE817M09600 piston kit is a trusted upgrade for enthusiasts seeking increased performance and durability in their Honda TRX450R/ER engine.
Whether you're rebuilding or upgrading, this piston kit offers precision engineering and high-quality materials to deliver consistent, high-level performance in off-road and racing environments.
