The smooth-running heartbeat of the 90-degree V-twin will never be mistaken for the rhythmic pulsing of a 45-degree American mill, but the fuel-injected, water-cooled DOHC motor does a commendable job of hustling the Hyosung down the road. Aside from a slightly bigger bore and a five-speed (rather than six) gearbox, the ST7's engine is in essentially the same state of tune as Hyosung's GT650R sportbike, which means it spins as high as the Suzuki SV650 engine it emulates. With what feels like a 10,500-rpm rev ceiling, the ST7 is surprisingly fun to flog and impressively quick. Although the bike tips the scales at a claimed 538 lbs. ready to ride, the Hyosung's small engine is unencumbered by that weight, launching off the line and accelerating to freeway speeds midway down the entrance ramp. Triple-digit velocities are not out of the question, and making a pass is as easy as rolling open the throttle. The ST7 positively stomps the Honda Shadow Phantom we tested a few months back, and handles pretty well, too.
