It is supposed to be for a Honda CB750, though somehow looks like not so much, anyone have one and know what bike its for ?
Sure it could be adapted but it's not made for rigid. My vote is HD swing arm 4 speed.Looks like the original Two Ton Ho fender from the '70s. Not that twisted never straight Jesse James Taiwan crap. Can't remember the name of the shop who made them though. Looks like it'll fit any ridgid you adapt it to.
