Wiseco KX125 2001-2002 Piston Kit with Gaskets PK1502

When you're rebuilding a KX125 top end, cutting corners on piston quality will cost you—either in lost performance or catastrophic engine failure. The Wiseco KX125 Piston Kit delivers the precision and durability needed to safely run your 2-stroke at the edge of its limits, with a complete gasket set included so you're not scrambling for parts mid-rebuild. Built from forged high-silicon bar stock, this kit minimizes thermal expansion and maintains consistency even under extreme combustion temperatures.

What sets Wiseco apart is the engineering specificity: the rings and components are tailored exclusively for Wiseco engines and are not cross-compatible with other manufacturers. This precision-engineered fitment ensures optimal ring seal, compression, and longevity—critical factors that directly impact power delivery and reliability on the track or trail.
