Using your AS3 radiator guard is a breeze. First, unpack the guard and check that all the parts and the mounting hardware are included. Follow the fitting instructions that come with it to attach the guard to your 2016 - 2023 Honda NC 750 X or NC 750 X DCT. Make sure all the bolts are tightened properly. As for maintenance, a simple wipe - down with a soft cloth every once in a while will keep it looking good. If it gets dirty, you can use a mild soap and water solution, but avoid abrasive cleaners as they could damage the textured matt black finish. Also, regularly check the mounting bolts to ensure they haven't come loose during your rides. And remember, your radiator guard is covered by a 12 - month warranty, so if you encounter any issues, don't hesitate to reach out.
