Using these throttle cables is easy. Just install them according to your motorcycle's manual. When you ride, you'll notice the improved throttle control right away. For maintenance, regularly check the cables for any signs of wear or damage. If you see fraying or kinks, it's time to replace them. Keep the cables clean by wiping them with a soft cloth. Since they have a smooth gloss finish, dirt won't stick easily. Store them in a dry place when not in use. Remember, these cables are custom - fit for specific Fantic models, so make sure your bike is one of the compatible ones (2021 - 2023 Fantic XEF 250 and 2022 - 2023 Fantic XEF 450, excluding the XEF 250 Trail). And if you have any special color or order requests, just ask the UK company that offers a 12 - month warranty.
