The VERTEX 22356A piston kit is designed for optimal performance and durability in Yamaha YZ and WR250 models. Constructed from high-quality gravity-cast aluminum alloy with 18% silicone content, this piston offers excellent strength and heat resistance. The piston is heat-treated through a T-5 hardening and tempering process, ensuring enhanced toughness and longevity for demanding riding conditions. Its lightweight design contributes to improved acceleration and handling, making it a reliable choice for enthusiasts seeking factory-quality replacement parts.
To facilitate a faster break-in period and extend piston life, the piston skirt is coated with a high-tech Molybdenum Disulphite layer. This coating reduces friction and wear during initial use, promoting smoother operation and longer component lifespan. The kit includes everything needed for a complete replacement: piston, rings, wrist pin, and circlips, simplifying installation and ensuring compatibility.
This OE replacement piston provides a precise fit and consistent performance, making it ideal for restoring your Yamaha YZ or WR250 to factory standards. Whether rebuilding after a race or maintaining your bike’s peak condition, the VERTEX piston kit delivers quality and reliability built to withstand rigorous riding environments.
