Product Description
Please note that a few select piston kits do not include the ArmorGlide skirt coat.
- Each piston is built from race proven designs that are chosen by the top race teams in all forms of racing including Supercross, Motocross, GNCC, Superbike, and more.
- 4-stroke kits feature a ‘race-ready’ dome finish with smooth edges for improved combustion flow. Horizontal slot-pin oiling reduces friction and provides scuff resistance, along with a pressure seal groove for maximum ring seal.

- 4-stroke race applications feature Wiseco’s ArmorGlide™ skirt coating to provide reduced friction and noise to contribute to increased horsepower.
- Dedicated forgings used for superior strength to weight ratio utilizing aerospace alloy.
- High Performance ring kit and alloy pin included with each piston kit for extended life and sustained power.
