Cast Piston Kit

ProX piston designs are usually similar to the OEM/stock configurations, although sometimes these designs are adjusted whenever the ProX engineers discover an opportunity for increased performance

ProX cast pistons are very stable

ProX cast pistons are made through gravity casting using aluminum alloy with approximately 18 percent silicon content

Silicon plays a vital role in ProX’s cast piston manufacturing, as it decreases thermal expansion

ProX two-stroke pistons are manufactured for both cast iron cylinder bores and Nikasil cylinder bores

Regarding Nikasil cylinder bores, ProX offers a variety in oversizes graded in A/B/C/D sizing, each going up 0.01mm in diameter
