Using these AS3 radiator braces is easy. First, find the instructions that come with the package. They'll guide you step - by - step on how to fit the braces to your 2018 - 2020 Gas Gas EC 250, XC 250, EC 300, or XC 300. Make sure to use all the bolts provided for a secure fit. When riding, the braces will protect your radiators from damage, but try to avoid big impacts if possible. For maintenance, just give them a regular clean with a mild soap and water to keep the matt black finish looking great. Check the bolts every once in a while to make sure they're still tight. If you have any issues, the UK company offers a 12 - month warranty, so you can reach out to them for help.
