This Wiseco High-Performance Piston Kit is built for riders who want dependable performance from their 2-stroke engine—whether you ride trails or race. The piston is forged from a high-silicon 4032 aluminum alloy to improve strength and reliability under heat and load, helping maintain power and durability over time.
Its advanced forging design and piston skirt profile are engineered to support strong horsepower and torque output, while high-tech details (like titanium nitride-coated rings and E-coating on key wear areas) help reduce wear, resist micro-welding/galling, and keep performance consistent. For racers and tuners, the GP-series approach focuses on sealing and predictability to deliver a more controllable powerband and strong top-end pull.
Key features:
✅ Forged high-silicon 4032 aluminum alloy for strength and dependability
