If you shorten transmission you get higher torque (to the wheel), lower rev, and same power. Power = torque x rpm and thus juste follows the torque (engine) curve as rpm increases.
The NC 750 has decent torque, it's power is limited by the low max rpm. In road use, it is a far better choice than small 4 inline that may produce more than 100 bhp but at very high rpm due to limited torque.
To me torque is the real thing. I own two other more powerful bikes but love the engine response of the NC. Of course for track use I use the triple.
