CYLINDER WORKS Piston Kit for Yamaha YFZ450R and YFZ450X 97.96mm +3.0 - High-Performance Forged Piston Set

Upgrade your Yamaha YFZ450R or YFZ450X with the CYLINDER WORKS Piston Kit, designed for optimal performance and durability. This kit includes a forged piston, piston rings, wrist pin, and circlips, providing a comprehensive solution for engine enhancement. Crafted with precision, the piston features a high-tech molybdenum disulphide coating on all piston skirts, which ensures faster break-in times and significantly extends piston life by reducing friction and wear. The forged construction of the piston increases engine displacement, resulting in improved torque and peak horsepower for more aggressive riding or competitive performance. Each piston undergoes heat treatment through a T-5 hardening and tempering cycle, ensuring strength and reliability under demanding conditions. Compatible with Yamaha YFZ450R models from 2009 to 2017 and the YFZ450X from 2010, this kit is engineered to deliver consistent power gains and longevity. Whether rebuilding or upgrading, the CYLINDER WORKS Piston Kit provides a proven solution to enhance your ATV’s engine performance with precision engineering and high-quality materials.
