Using your AS3 radiator guard is easy. First, refer to the fitting instructions that come with the package. Gather all the necessary hardware included and start mounting the guard onto your 2019 - 2021 Honda CB 650 R. Make sure to follow the steps carefully to ensure a proper fit. When riding, the guard will do its job of protecting the radiator from stones and debris. As for maintenance, you can simply clean it with a mild soap and water solution. Avoid using harsh chemicals as they may damage the textured matt black finish. If you notice any signs of damage during your regular checks, contact us right away as your guard is covered by a 12 - month warranty.
