Sprockets will wear out over time, resulting in a myriad of problems for you and your bike. For one, this can make tensioning the chain difficult, which may cause the chain to fall off and jam in the drive train. Also, the chain may not roll off the sprocket as it turns, causing the wheel to lock up. To avoid these problems, you'll want to replace your sprockets when you see the teeth are worn out. But you don't want just any other replacement part. You want something that's designed specifically for your ride and made for long-lasting performance. Get your ride back in action with the 17mm Countershaft Sprocket Drive Gear from RUTU. This sprocket is designed to be a reliable replacement for old sprockets in different power sport vehicles using 420 chain sizes. You can confidently install it in 50cc-125cc bikes and ATVs with a 17mm engine countershaft. To make the sprocket tougher, we process it with heat-treatment. This improves the strength of the sprocket, allowing it to stand well against wear and tear. Aside from that, the sprocket features an upgraded gear curve which helps reduce transmission friction, which in turn helps extend the life of your chains.
