I believe this Jockey Shift Chopper is using a Buell motor.  I love the Springer front end and the drop frame is neat bringing the tank right up to the riders chest.  One very unique feature is the jockey shift.  I've never seen a Buell with a jockey shift before the way they set it up is very cool.  It doesn't stop there on this chopper however.  If you look closely at the end of the exhaust pipe you'll see the spark plugs for the Jersey Torch.  It's too bad this bike show was in an arena or it may have been possible to se the flames coming out of the exhaust.  Update!  I found this Buell Chopper made by Twisted Choppers on Craigslist in Minneapolis.  The asking price is $15,000
