Using these AS3 radiator braces is easy. First, find the fitting instructions that come with the product. Follow the steps carefully and use the provided bolts to attach the braces to your 2011 - 2013 Husqvarna TC 449, TE 449, or TE 511. When you're riding, the braces will protect your radiators from damage. Just remember, while they're strong, don't push them to extreme limits. For maintenance, you can clean them with a mild soap and water solution occasionally. Check the bolts regularly to make sure they're tight. If you notice any signs of wear or damage, contact the UK company for support as they offer a 12 - month warranty.
