Wiseco Piston 68.00 mm Honda TRX250R FourTrax 1986-1989 562M06800

If you're pushing your TRX250R to its limits on the track or trail, a stock piston won't cut it. The Wiseco 68.00 mm +2.00 mm oversized piston delivers measurable gains in compression ratio and power output while maintaining the reliability you need for extended service intervals. Built with high-silicon aluminum forgings and race-proven engineering, this is the upgrade serious competitors choose when stock performance becomes a bottleneck.

This complete piston kit includes everything you need for installation: forged piston, compression rings, wrist pin, and circlips. The E-coated crown and ring grooves resist micro-welding and wear, while the ultra-stiff strutted design holds up under extreme load. Boost ports have been removed to create a flatter, more usable power band across the RPM range—no power dips, just consistent pull to redline.
