airtech makes the drixton fairings for the stock cb450/500 frame. I have seen plenty of full fairing cafe racers and the h1 in my garage has a full works h1r fairing and a headlight but is far from being together.
Hey thunderzy, funnily enough I am considering the same thing with the same bike. I have the bike and a fairing mount welded to the frame, its a long way from finished, actually just beginning. I would like to make it "convertible". I'm a long way off from finishing or knowing what fairing i will eventually use, but really want to finish it off. I will try to post it up in the projects section when i get the chance, maybe this weekend.
