Using these foot pegs is easy. Just replace your old OEM foot pegs with these AS3 Racing foot pegs on your Fantic XX 125 or XX 250. Make sure they are firmly installed. When riding, you'll notice the improved grip and larger platform, which can make your ride more comfortable. For maintenance, regularly check the stainless steel teeth. If any are worn out, you can use the 5 replacement teeth that come with the set. Keep the pegs clean by wiping them down with a soft cloth. Avoid using harsh chemicals that could damage the anodised finish. If you have any issues, remember the pegs come with a 12 - month warranty, so you can reach out for support.
