The naked GT650 Comet, Hyosung's mid-size V-twin roadster with a liquid-cooled 90-degree twin, six-speed gearbox and upside-down fork. A German road test praised its upright riding position and sharp handling, but called the instruments basic, the carburettor choke-dependent and the engine weak below about 5000 rpm. It was sold as a low-priced bargain.
