Those are the bars from Tucker Rocky. I probably cut the ends down a little to make them narrower, but they didn't come from Honda.
Try strickscycle.com, shop online, Tucker Rocky Street, Control, you have to hit some weird display for Bike Master, and there's the bars. You probably want European or Superbike. If you can't find what you want, I'd bet they ship them for you. If they won't- I will. Lord knows, folks in England have helped me before.
