Using these radiator braces on your 2019 - 2021 Honda CRF 450 L is a breeze. First, find a flat and stable surface to work on. Then, follow the included fitting instructions and use the provided bolts to attach the braces to your bike. Make sure all the bolts are tightened properly to ensure a secure fit. When it comes to maintenance, it's simple. Regularly check the braces for any signs of damage, like cracks or loose parts. If you notice any issues, contact the UK company for support under the 12 - month warranty. Keep the braces clean by using a mild soap and water, and avoid using harsh chemicals that could damage the matt black finish. That's all there is to it, and your radiator will stay well - protected for a long time.
