Wiseco Piston Kit with Gaskets for Honda XR250R 1986-2004 PK1223

The stock piston in your XR250R will eventually wear, lose compression, and cost you performance when you need it most. A quality rebuild with Wiseco's forged-aluminum piston kit restores your engine's original power while improving durability for hard riding and racing. This complete kit includes everything you need for a proper top-end refresh—no hunting for individual gaskets or ring sets.

Wiseco engineered the PK1223 with a 10.5:1 compression ratio to deliver sharper throttle response and stronger acceleration off the bottom. The aerospace-grade forged aluminum construction resists detonation and thermal stress, while the advanced heat-dissipation design keeps combustion temperatures in check during extended trail work or race conditions. Since this kit ships with piston rings, wrist pin, circlips, and a complete gasket set, installation is straightforward for experienced mechanics.
