Using this front brake disc guard is easy. First, remove the front wheel spacer on your 2013 - 2023 Beta 125 4T LC Enduro. Then, mount the guard in its place. Make sure it's properly aligned so the vents are aimed at the brake caliper. When riding, it will protect your front brake disc from rocks and other debris on the road. As for maintenance, regularly check the guard for any signs of damage or wear. If it gets dirty, you can clean it with a mild soap and water. If it's damaged, you can use the available replacement guards. Also, keep an eye on the mounting bracket to ensure it remains secure and doesn't loosen over time.
