That's the same I thought when I saw your Nighthawk. I could't believe how that muscle-looking european version could look that dull and boring in the US robes. I'm telling you, the Seven Fifty, though not as "aggresive" as the Honda Hornet, the Suzuki Bandit, the Kawa ZR-7 or the Zephyr, is a hell of a nice naked bike. Being far form the original 4 pipes, at least it has one pipe in each side, that makes it more "symmetrical" and less "sport" when seen from behind.
Then you have some other muscle naked bikes, as the Honda CB1300

The Yamaha XJR1300

and the Suzuki GSX1400

All of the three are terrific looking bikes, with an aggresive and sporty touch -specially the Honda IMO-, but they have a big drawback. They can benefit from lots ot torque that makes driving easy as you don't have to shift often, but a big weight and the lack of fairing makes it impossible to extract all their potential. The Seven Fifty have the best balance, again in my opinion, between looks, power and cheap maintenance.
