Do you know your fork tube diameter for sure? Most '86 Rebel 250s have 33mm forks, so you'd need 33mm clip-ons, not 50mm, have you measured yours to confirm?I have this '86 Rebel 250 bobber and want some clamp-on bars that could be lower than stock. I've seen sizes like 50mm mentioned, but isn't it that that refers to the fork diameter? Help since I'm not totally sure what size fits the Rebel.
