Wiseco's Piston Kits are offered for nearly every popular application in the powersports market. These kits contain everything you need to complete your piston repair, the first time. High quality parts specifically chosen by us to match our forged pistons are included in this kit for easy one stop shopping. 2-stroke kits feature our Pro-Lite pistons that are CNC machined for optimal cam shape and profile for peak HP and service life. 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 Armor Glide skirt coating to provide reduced friction and noise to contribute to increased horsepower. 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, Super-bike, and more.
