Why Wiseco Pro-Lite?

Wiseco Pro-Lite pistons are specifically designed for 2-stroke engines. The 4032 aluminum alloy provides excellent strength-to-weight ratio, allowing for higher RPM and quicker throttle response. The big bore option gives young racers the extra displacement they need to stay competitive in the transition class!
