Wiseco Piston Kit with Gaskets for Yamaha YZ250 1995-1998 PK1567

If you're running a YZ250 at the limit, a worn top-end will cost you power, reliability, and race results. The Wiseco Piston Kit PK1567 delivers a complete engine refresh with forged-aluminum construction that handles sustained high RPMs and thermal stress without compromise. Rebuild your engine to factory-plus specifications and reclaim the horsepower and durability your bike demands.

This kit includes everything needed for a full top-end overhaul: a high-silicone forged piston, matched ring set, wrist pins, circlips, and complete gasket kit. Wiseco's precision engineering minimizes thermal expansion, reducing blow-by and maintaining compression consistency lap after lap. Because the piston and rings are factory-matched, you eliminate the guesswork and compatibility issues that can plague mixed-component rebuilds.

Whether you're prepping for competition or restoring a well-loved 1995–1998 YZ250, this kit ensures your engine runs at peak performance with the durability to handle years of hard use.
