Wiseco Piston Kit 2.0mm Oversize for Yamaha YZ 80 1988-1992

Upgrade your Yamaha YZ 80 (1988-1992) with the high-performance Wiseco 2.0mm oversize piston kit, engineered for unparalleled durability and power. This forged piston kit is designed to deliver maximum strength and reliability, making it ideal for both aggressive trail riding and competitive racing applications.

Description

The Wiseco high-performance piston kit is meticulously forged from a premium high-silicon aluminum alloy, ensuring superior strength and long-lasting dependability under extreme conditions. This 2.0mm oversize piston is specifically crafted for your Yamaha YZ 80, providing a precise fit for models from 1988 to 1992. The innovative forging design, combined with an optimized piston skirt, works to maximize both horsepower and torque, giving you a significant edge on the track or trail. Each component in this kit, including the forged piston, rings, wrist pins, and circlips, is engineered for peak performance. Featuring ultra-stiff strutted forgings and titanium nitride-coated rings, this kit offers maximum compression ratios for a sustained power increase. Furthermore, the piston crown, ring grooves, and pin bore are E-Coated, providing exceptional wear resistance, protection against micro-welding and galling, and enhanced detonation resistance. As a GP Series part, it benefits from less external machining to improve bore sealing and compression, with boost ports removed for a more predictable powerband and stronger top-end pull, making it an excellent choice for a high-performance Yamaha YZ 80 piston replacement.
