Description
Stock pistons are engineered for longevity, not peak performance—and every heat cycle pushes them closer to failure. The Wiseco Piston Kit delivers the precision engineering and premium materials needed to restore your Husqvarna CR250 or WR250 to competitive specifications, or exceed them. Whether you're rebuilding after a seizure or chasing measurable gains in throttle response and combustion efficiency, this oversize kit addresses the root cause of power loss with a proven solution.
Wiseco pistons are purpose-built for high-RPM punishment. The high-silicon aluminum alloy resists thermal stress that destroys standard pistons, while CNC-precision tolerances ensure zero slop and consistent compression across your entire power band. You'll feel the difference in snap off the bottom and sustained pull through the mid-range.
