I believe frame, swing arm shock and forks are all unique to the B King. Brakes wheels and sprockets are shared.Lookin' to build a hooligan/street fighter type bike. I'm too old to handle the clip ons of the Busa so I'd mount bars and remove plastic and put on dual round headlights possibly. Couldn't recall from all the readings in the mags when the Bking first came out, but do the bikes have the same frame, engine, brakes, etc. I know the Kings swingarm is slightly longer and the exhaust is different, but otherwise the same???
