The Hyosung GV 650 looks like a total winner at the spec sheet, and at first glance, but that’s why we have these tests. It is an impressive machine in many aspects, especially at the price, but it let us down in a few key ways. The biggest issue was a cracked radiator on our second day of testing. We got it fixed and finished the test without another hiccup, but the event itself made us leery of the bike. The mechanic who fixed it said the radiator was installed improperly, putting pressure on the bolts, which may have caused the crack. During the overheating itself, the temp gauge never read higher than 3 bars (of 10), while later on it read as high as 4 in hot, slow riding. That said, for a bike that was so hot the insides of the exhaust pipe glowed red, it recovered without a hiccup, running smooth as ever.
