Description
When you’re running a Honda TRX300EX at the edge of performance, your stock piston won’t cut it. The Wiseco Piston Kit PK1027 delivers the strength and thermal stability needed for high-RPM reliability, whether you’re pushing hard on the track or putting serious hours on the trail. This is a complete top-end solution that eliminates guesswork during your next engine rebuild.
Wiseco engineered this kit specifically for the TRX300EX platform, combining a high-silicone forged piston with matched rings, wrist pins, circlips, and gasket set. The forged construction resists deformation under extreme heat and cylinder pressure, while the precision manufacturing ensures minimal thermal expansion—critical for maintaining proper ring seal and long-term reliability. Installation is straightforward for anyone comfortable with basic top-end work, though professional assembly is always recommended for optimal results.
