51T Aluminum Rear Sprocket for KTM 450 XC-W (2007-2016) - Durable Motorcycle Drive Sprocket for Off-Road & Trail Riding

Pro X Aluminum Rear Sprockets are manufactured from 7075 T6 aluminum alloy, a base material with excellent wear properties and a lifespan that will outlast most of the competition. Each sprocket is CNC machined to OEM specs and features specially designed mud grooves that attract and disperse buildup away from wearing surfaces between the sprocket teeth to greatly increase the life of the sprocket and your chain. Pro X aluminum sprockets will bolt up to your stock hub for a direct OEM replacement and attach with countersunk holes for a flush fit. When you don't want to get let down with a sprocket that shows premature wear, pick up a Pro X Aluminum Rear Sprocket for a great balance of price, performance, and weight.
