Using your AS3 Factory rear sprocket is easy. First, make sure your KTM bike is turned off and on a stable surface. Carefully remove the old sprocket and replace it with the new 51T AS3 sprocket. Ensure it's properly aligned and tightened according to your bike's specifications. When it comes to maintenance, it's a good idea to clean the sprocket regularly. You can use a mild soap and water solution to remove dirt and debris. After cleaning, dry it thoroughly to prevent rust. Check the tightness of the sprocket bolts periodically, especially after long rides or rough terrain use. Remember, this sprocket is designed to be durable, but avoid extreme impacts or over - stressing it. If you notice any signs of damage or unusual wear, it's best to contact the UK company that offers a 12 - month warranty for further advice.
