I bought one in March, the build quality is good, average fuel is between 70 - 80mpg. the engine does vibrate from around 70mph and was really bad above 80mph, I now have covered 4,000 miles and the vibration is reducing. It is a great bike to ride, the handling is amazing with its Pirelli Angel tyres. - KYB upside down forks, The brakes are the best I have ridden with (twin discs) with the exception of my BMW K1200GT which had servo assist. I sold the BMW to buy the Voge as the weight of the BMW was now too much for me.
My other bike is a Honda NC750X the build quality is no better than the Voge, in fact in some ways it is better, Honda use horrible plastic fasteners to hold the plastic panels together, Voge use proper dome headed bolts. So far I am very pleased with my cheap Chinese bike.
