Using your AS3 front brake disc guard is a breeze. First, take out the front wheel spacer on your KTM motorcycle and replace it with the mounting bracket of the disc guard. Make sure it's firmly attached. When you're out riding, this guard will keep rocks and debris from hitting your front brake disc, giving you peace of mind. Remember, although it's made of strong plastic, avoid hitting it against really hard objects. For maintenance, clean it regularly with a mild soap and water solution. Check the mounting bracket occasionally to ensure it's still tight. If you notice any signs of wear, you can easily get a replacement guard. Enjoy a safer and better - performing ride with your AS3 brake disc guard.
