The Korea-based S&T Motors Co. Ltd. (formerly Hyosung) has announced its GT650R, which will now be fitted with a fuel-injection system instead of the earlier carburetor. The bike’s DOHC, 8-valve, liquid-cooled, 647cc v-twin engine is being updated, and will now produce 80bhp and 67Nm of torque.

The Hyosung GT650R, which weighs around 208 kilos, rides on 17-inch wheels, with 120/60 (front) and 160/60 (rear) ZR-rated tyres. The bike is fitted with a six-speed gearbox, adjustable monoshock at the back, USD fork, 300mm twin brake discs at the front (with radial-mount, four-piston calipers) and 230mm rear disc brake. T

Motomag’s riding impression

For those who may be looking for a budget-spec sports 600, the Korean-made Hyosung GT650R looks like a good bet. Well, at least it does on paper. But does it measure up in the real world? Here are some excerpts from Motomag’s riding impression of the bike:

On paper, the Korean bike provokes enthusiasm. But in the real world… things turn out to be a bit different. Close up, the bike looks and feels cheaply put together and lacks refinement. On the move, it quickly informs you of its dynamic limits. The suspension simply isn’t very good and the bike doesn’t feel stable in bends. Also, the engine’s fuel-injection system needs more work – throttle response is inconsistent and getting on and off the throttle at higher revs can be jerky.

The Hyosung GT650R isn’t exactly terrible, but it’s simply not in the same league as, say, a Suzuki SV650 or Kawasaki ER-6. To sum up, the bike, which is barely 100 euros cheaper than an SV650, isn’t worth it. This verdict may seem harsh, but in a market where competition is strong, the Hyosung simply doesn’t have any special talents to recommend its case.
