If you want an American motorcycle that performs, this about your only choice.

The Motoczysc is really a breakthrough in both chasis and engine design.
"Counter-rotating longitudinal crankshafts to improve handling, four-cylinder, triple overhead cam, tuned-flex forks to reduce chatter and provide consistent fork action, a quick access transmission, a long swingarm with constant chain tension. It is all the type of advanced thinking that we reveled in when John Britten was making his own carbon wheels in his backyard shed."
The Buell XB12RR is twice the price of the Ducati 1098 (160 HP and 90 ft lbs) Buell has some novel engineering, but nothing can overcome those ancient vtwins.
Triumph was doing oil in the frame 30+ years ago on the Bonnie.
On a personal note, the biggest POS I've ever ridden was a Buell.
