Wiseco Racer Elite Pro Series Piston Kit for Yamaha YZ/WR450F, 97.00 mm (REP825M09700)

The WISECO Racer Elite Pro Series Piston Kit is engineered for demanding track conditions and high-performance Yamaha YZ450F and WR450F applications. Part number REP825M09700 is forged from high-tensile 2618 aluminum alloy to provide exceptional strength, durability, and resistance to the stresses of intense engine operation. Its race-focused construction supports reliable performance in environments where heat, load, and sustained high engine speeds are common.
ArmorPlating™ surface treatment on the piston crown helps protect against extreme heat and harsh operating conditions, while the ArmorFit™ skirt coating conforms to the cylinder bore for an optimized fit and reduced friction. Lateral gas ports help improve ring seal and reduce blow-by, contributing to efficient combustion and consistent engine performance. The included precision-lapped compression ring is designed to create a tighter ring-to-groove seal for dependable sealing under demanding conditions.
This WISECO piston kit also includes a DLC wrist pin engineered for ultra-low friction and high wear resistance. The combination of forged construction, advanced coatings, optimized ring sealing, and durable wrist-pin technology makes the Racer Elite Pro Series a strong choice for competition-focused engine builds and performance-oriented maintenance. Manufactured in the USA, the REP825M09700 kit is designed for Yamaha YZ/WR450F engines using a 97.00 mm piston.
