Upgrade your Yamaha YZ80 with the WISECO 520M04800 piston kit, engineered for trail and racing enthusiasts seeking maximum durability and power. Crafted from high-silicon aluminum alloy, this forged piston ensures exceptional strength and dependability under demanding riding conditions. The innovative forging design and piston skirt geometry deliver optimal horsepower and torque, making it an ideal choice for competitive riders and serious tuners. The WISECO 520M04800 piston features forged construction with ultra-stiff strutted forgings, which contribute to enhanced performance and longevity. The titanium nitride-coated rings, combined with E-coating on the crown, ring grooves, and pin bore, provide superior wear resistance and protection against micro-welding, galling, and detonation. These advanced features allow for higher compression ratios, resulting in increased power output and more sustained performance over time. Designed specifically for Yamaha YZ80 models, this piston kit includes rings, wrist pins, and circlips * all engineered to match the high-tech specifications of the piston. The piston*s design reduces outside machining, which helps seal the bore for increased compression and improved powerband predictability. Additionally, the removal of boost ports enhances the top-end pull, providing a more aggressive and responsive power delivery. For optimal performance, cylinder sleeves must be purchased separately. Service intervals are extended with the use of WISECO Racer's Choice pistons, making them suitable for experienced racers and tuners aiming for consistent, high-level performance. Whether you're rebuilding for competition or upgrading your trail bike, this piston kit offers the reliability and power enhancement you need to stay ahead of the pack.
