The engine performance of the GT650R is great but the most heart breaking disadvantage is its very heavy body and bad power to weight ratio. The motorcycle comes with a nice 647 cc, 2-cylinder engine producing 72.68 BHP @ 9,000 rpm and 60.9 Nm @ 7,500 rpm. The gearbox is 6-speed but the kerb weight points at 215 kg. The bike comes with twin 300 mm disc brakes at the front and 230 mm at the rear. It comes with a 5.5 second 0-100 kmph sprint and a top speed of 210 kmph.
