Wiseco Piston Kit for Honda TRX250R 1986 69.50mm PK1083

When you're pushing a TRX250R to its limits, stock pistons become a liability. The Wiseco PK1083 kit delivers the thermal stability and durability required for sustained high-RPM performance, whether you're racing competitively or running aggressive recreational loads. This is a complete top-end solution engineered to handle the demands of high-octane fuel and elevated combustion pressures without compromise.

The high-silicone forged aluminum construction resists thermal expansion better than cast alternatives, maintaining precise ring seal across temperature swings. You get a full rebuild kit here—piston, rings, wrist pins, circlips, and gaskets—so you can do a proper job in one service interval. Wiseco's precision manufacturing ensures fitment accuracy that translates directly to reliable performance and longevity.
