Using this AS3 front brake disc guard is easy. First, remove the front wheel spacer from your 2009 - 2013 Husqvarna TC, TE, CR, or WR bike (from 125 to 510cc). Then, attach the guard in its place. You'll enjoy better protection for your brake disc and improved braking performance thanks to the cooling vents. When it comes to maintenance, regularly check the mounting bracket to make sure it's secure. If the guard gets dirty, you can simply clean it with a mild soap and water solution. In case the guard gets damaged, replacement guards are available. Always make sure the guard is properly installed to ensure it works effectively.
