Description
Stock pistons in your TRX250EX are a compromise between cost and performance—they limit your engine’s potential and wear faster under aggressive riding conditions. The Wiseco 4935M06900 piston kit replaces them with forged-aluminum internals engineered for sustained high RPM operation, giving you measurable gains in power delivery and ring sealing. If you’re rebuilding after wear or stepping up your ATV’s output, this kit delivers the durability and efficiency that separates amateur builds from professional-grade work.
