Those forks were probably originally meant for or came on an atc90/110 that someone had modified at sometime. If the forks were meant for a 250r, then they wouldn't fit on your trike. That sticker should not be too hard to copy for someone who does things like that. Contact blue27, a member on here, he may be able to help you on the sticker reprinting.
