I know nothing of these bikes, but based upon what I just read and saw on that page, if money was not a factor for me, I'd be calling first thing in the morning and buy 1. And I agree with Ace, that motor isn't designed to wind up, it's designed to rip your pants off right out of the gate. It probably has a taller final gear ratio than you would find on a 600 sport bike, as it will have more torque up to 5k-6K RPMs than you'd know what to do with. From the pic it looks like it is based off of a S&S 130CI 130HP crate motor which runs as I just mentioned. The styling I could take or leave, but the performance that bike is packing is impressive.
