Using your AS3 Performance radiator braces is a breeze. First, refer to the fitting instructions that come with the product. Gather all the bolts and tools needed for installation. Make sure your bike is turned off and on a stable surface. Attach the braces carefully to your Husaberg FE 450 or FE 570 radiator following the steps in the instructions. As for maintenance, it's simple. Regularly check the bolts to ensure they're tight. If the braces get dirty, you can use a mild soap and water solution to clean them. Just avoid using abrasive cleaners as they might damage the matt black finish. Keep an eye on the radiators and braces for any signs of wear or damage, and if you notice anything, contact the UK company as they offer a 12 - month warranty.
