Fairings are one of the most expensive components on a bike. When a motorbike gets dropped or laid out, the cracked or scratched up fairings can be more than enough to warrant the insurance company to total the bike rather than pay for repairs. Fortunately for you, a bike does not need brand new fairings in order to operate. In fact, it may not need any fairings at all to still be functional.
If you see a motorbike that has damage to the plastic or fiberglass and little other noticeable problems, chances are that motorbike simply had cosmetic damage. Fairings can be bought wholesale, used, or even cobbled together out of bonding materials on the cheap. Your motorbike might not look as pretty as it did before it got totaled, but it will run the same.
