Product description
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
