I've had lots of bikes (20 or so). I will say the 919 has the finest STREET motor of any of them. Very linear power delivery, plenty of torque, not much shifting required. But as good as the motor is, the suspension is equally bad. The front is too soft, the rear is too stiff with too little damping (can you say pogo stick). Cornering at anything over 7/10th pace gets sketchy. Compared to my Buell...I was significantly slower on the 919, and was working harder to get the 919 through corners. Depending on your riding style, the 919 may be a good choice. It's a top notch commuter, a good sport tourer, & quick in a straight line. But if you enjoy leaning to the edge of your tires I would say look elsewhere.
