Description
A piston kit is the foundation of reliable engine performance—wear or damage here cascades into catastrophic failure. The Wiseco 0.50mm oversize piston for your YFM350 Grizzly delivers the durability and precision fit you need to maintain peak power delivery, whether you’re pushing hard on the track or tackling challenging terrain. This complete kit includes rings and circlips, eliminating the guesswork and getting you back in the saddle faster.
Wiseco pistons are engineered with high-silicon alloy construction, which resists scuffing and thermal stress far better than cast alternatives. The 0.50mm oversize allows for a precision boring operation that restores your cylinder to factory tolerances, maximizing compression and minimizing blow-by. Every piston is CNC-profiled to exact specifications, ensuring consistent fit across your YFM350 Grizzly model years 2007–2014.
