i looked seriously at the bking also. i've got a naked busa and i don't like being leaned over anymore like stock busa's or 14's. I imagined i would get rid of the side panels totally, and the tiny headlight that looks like it came off the transformer movie set, and put on something that fits the look of the bike better with a moderately high windscreen.
Considering you can get a brand new king for 9k, it is the best deal on a powerful bike out there. there's even one here in seattle with akropovic cans brand new for 9k at a dealer. i'd make a comfortable long haul bike out of it. i wish i could put that swingarm on my busa.
I've also got a 300 hp b-bird that i've installed naked bike handlebars on, and i will never go back to clip-ons. The b-king is already comfortable, and the back half of the bike looks great stock with aftermarket cans.
