Here's another take on the Buell idea, a Buell Sport Chopper. The owner took a Buell XB9S Lightning, removed the front fork, wheel and brakes plus the rear swingarm and wheel along with the Buell engine and built himself a frame that turns it into a sport chopper. It looks pretty decent, though, as even the owner admits, it's not very comfortable after a while since the forward controls plus the long reach to the bars make for bad ergonomics. If the foot pegs were back under the rider, this might have some possibilities.
With Erik Buell's emphasis on sportbikes, I wonder if a similar idea ever crossed his mind, or if it did, whether Harley would allow him to build it. A Buell sport chopper might take V-Rod sales away but the upside down forks and perimeter brakes and other Buell items, could make for a chopper/cruiser with some pretty decent handling. Interesting.
