Wiseco Piston Kit - 49.50mm Bore - +1.50mm - 520M04950

Unleash the full potential of your Yamaha YZ 80 with the Wiseco 1.50mm oversize piston kit, engineered for unparalleled performance and durability. This high-performance kit is specifically designed to fit Yamaha YZ 80 and YZ 80 LW models from 1985 to 1999, providing a significant upgrade over stock components.

Description

The Wiseco 1.50mm oversize piston kit is meticulously forged from high-silicon aluminum alloy, ensuring maximum strength and dependability under the most demanding racing and trail conditions. This advanced forging process, combined with an innovative piston skirt design, is engineered to deliver increased horsepower and torque across the entire RPM range. Riders will appreciate the enhanced durability and longevity that comes with Wiseco's commitment to quality. Each component in this kit, including the forged piston, rings, wrist pins, and circlips, is designed for optimal performance. The high-tech piston features maximum compression ratios and ultra-stiff strutted forgings, contributing to more sustained power output. Furthermore, the piston crown, ring grooves, and pin bore are E-Coated for superior wear resistance, preventing micro-welding, galling, and detonation. For a more predictable powerband and increased top-end pull, GP Series parts, like this Yamaha YZ 80 performance piston, feature less external machining and removed boost ports, sealing the bore for higher compression. This comprehensive kit provides a robust foundation for expert racers and tuners seeking to maximize their engine's potential.
