Wiseco GP Series Piston Kit for 125cc 2-Stroke Engines

Upgrade your 125cc 2-stroke engine with the premium Wiseco GP Series Piston Kit, engineered for exceptional endurance and high RPM performance. This comprehensive kit provides everything needed for a robust engine rebuild, ensuring maximum power and reliability.

Description

Designed specifically for 125cc 2-stroke engines, the Wiseco GP Series Piston Kit delivers unparalleled durability and power. Each piston, crafted from high-strength 4032 Aluminum Alloy, features a specialized electra-coating on the dome, ring groove, and pin bore. This advanced treatment provides maximum wear resistance, effectively protecting against micro-welding, galling, and detonation—critical for sustained high-RPM operation. With a precise bore size of 54.00 mm and a piston diameter of 53.94 mm, this standard oversize kit ensures a perfect fit and optimal engine sealing.

The unique design of GP Series parts incorporates less external machining, which significantly improves bore sealing, leading to increased compression and a noticeable boost in horsepower. Further enhancing performance, the proprietary ArmorGlide® skirt coating dramatically reduces friction and operational noise, allowing your engine to achieve its full potential with smoother, more efficient power delivery. Proudly engineered, forged, and machined in the USA, this Wiseco GP Series Piston Kit stands as a testament to superior quality and performance for serious motorcycle enthusiasts and racers.
