PISTON KIT KX60 88-04

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
