This sprocket has 48 teeth and fits 2021 Rieju MR 300 Racing, Pro, and Ranger models. Key features include a long - lasting hardened steel outer ring, a super - light aluminium inner ring, high resistance to bending and damage (perfect for enduro), an anodised finish with AS3 Performance branding, manufacturing by a world - leading sprocket maker, rigorous testing on tough sand tracks, a 12 - month warranty from a UK company, and you'll get the exact sprocket as shown in the picture.
Using this sprocket is straightforward. First, make sure your bike is the 2021 Rieju MR 300 Racing, Pro, or Ranger model. Then, carefully install the sprocket following the standard bike - part installation process. When riding, enjoy the smooth performance it offers, especially on tough terrains. As for maintenance, regularly clean the sprocket to remove dirt and debris. Check for any signs of wear or damage, like cracks or excessive tooth wear, at least once a month. If you notice any issues, contact the UK company for advice as it comes with a 12 - month warranty. Avoid using abrasive cleaners that could damage the anodised finish. And always follow the general safety rules when handling bike parts.
