The Wiseco 569M05000 Piston Kit is designed for Yamaha YZ80 models from 1988 to 1992. Forged from high-silicon aluminum alloy, it offers superior strength, reduced weight, and enhanced heat transfer for durability and performance. The innovative forging design and piston skirt maximize horsepower and torque while minimizing cylinder wall friction. This high-performance piston kit includes a forged piston, rings, wrist pin, and circlips. The piston features anti-detonation grooves and optimized ring land diameters to eliminate ring blow-by, ensuring maximum engine efficiency. Additionally, the E-Coated crown, ring grooves, and pin bore provide extra wear resistance and protection against micro-welding, galling, and detonation. Designed for both trail and racing applications, this piston kit delivers instant throttle response and increased torque. The Racer's Choice variant offers reduced weight and friction for improved power and throttle response, with extended service intervals for expert racers and tuners. Oversized pistons require cylinder sleeving, which must be purchased separately.
