Using this AS3 front brake disc and caliper guard is easy. First, remove the left wheel spacer from your 2010 - 2016 Kawasaki KLX 125 or 2009 - 2016 Kawasaki KLX 150. Then, attach the high - strength aluminium bracket in its place. Next, fit the plastic guard around the front brake disc and the lower part of the caliper. You're all set to ride! When it comes to maintenance, regularly check the guard for any signs of wear or damage. If the plastic guard gets too worn out, you can easily replace it. Also, keep the aluminium bracket clean to prevent rusting. Avoid using harsh chemicals on the guard as it might damage the plastic. Have fun riding with added protection!
