depending on the condition/brand they can be worth alot!! you can get an idea of what they will go for, check them out on ebay, search "supermoto wheels" or semthing like that, also may add value if they have a cush drive hub or what rotors/sprockets etc.
actaully i was kidding they really arent worth much, ill give you a hundred euros, that of course will have to include shipping across the pond :twisted: :twisted: kidding of course
