Hyosung has made changes to the ECU that make the GT650R an easier bike to ride within the city. However, it still houses a familiar four-stroke, 647cc, liquid-cooled, V-twin engine that puts out 72.6bhp of maximum power at 9000rpm, with peak torque of 6.2kgm at 7500rpm. The dual overhead camshaft engine breathes through four-valves and fuel injection is standard. The new GT650R still lacks adequate throttle response, power delivery feeding in with a slight delay. However, the 650R generates strong low and mid-range power, pulling with gusto from 3000rpm all the way up to 7000rpm.
