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
