I live in a complex where a lot of the guys have scooters. Many of them bought that china bike, like the vuka too, and most of them aren't happy. It's quality just isn't that good. And for someone who will do a lot of km's I would stay far away. Really, trust me, I saw the troubles these guys where I stay got. Other than the big brand names like yamaha and suzuki, and so on, I would highly highly highly recommend Kymco. (
