Key features include: a long - lasting hardened steel outer ring, a lightweight 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, testing on tough sand tracks globally, a 12 - month warranty from a UK company, and you'll get the exact sprocket style as shown in the picture.

Using this rear sprocket is straightforward. First, make sure your bike is turned off and on a stable surface. Then, remove the old sprocket and install the new AS3 Performance Factory rear sprocket carefully following the bike's manual. When riding, avoid extreme impacts as much as possible. For maintenance, regularly clean the sprocket with a mild cleaner to remove dirt and debris. Check the tightness of the sprocket bolts every few rides to ensure they are secure. If you notice any signs of excessive wear or damage, contact the UK company for assistance. Remember, this sprocket comes with a 12 - month warranty, so you can ride with confidence.
