Yamaha YZ250F 21-26 | YZ450F 23-26 Manual Cam Chain Tensioner

Designed from the ground up, XPR manual cam chain tensioners help reduce friction and drag, giving your engine more horsepower with a freer feeling, quicker revving response. The stock cam chain tensioner puts excessive tension on the cam chain guide, creating a lot of drag and heat which reduces horsepower and response. With our recommended adjustments, our manual cam chain tensioner allows you to set the tension for optimal performance. Features include: 2 titanium bolts and a titanium nut, for longevity with less weight. Strong and lightweight billet aluminum body. Hard-anodized coating for a durable finish. When using this product, it is recommended to check/and or adjust the cam chain tension after every 1-2 hours of riding. FitmentYZ250F 2021-2026YZ450F 2023-2026
