Pro-Lite™ Piston Kit

Restore crisp 2-stroke power and reliability with the Wiseco Pro-Lite™ Piston Kit. Built around Wiseco’s CNC-machined Pro-Lite piston, this kit is designed to deliver an optimized cam shape and profile for strong horsepower and excellent service life—ideal when you’re rebuilding a worn top end or preparing your bike for a new season.

Because it’s supplied as a complete kit (piston, rings, pin and clips, plus a needle bearing when applicable), it simplifies your rebuild and helps ensure correct component matching. Note that ring types are not interchangeable, and Wiseco rings/clips/wrist pins are intended for use with Wiseco pistons.
