I'm now the proud owner of a gay chinese scooter. Did the same as you are intending to and bought it for my g/f who was going to ride it. She doesn't. I do. And I love it. Its branded as a "Lance Venice" 150cc but most, if not all of the chinese scooters are made by the same company and badged differently with maybe some slightly different accessories on them. The 125/150cc engines are almost all "GY6" series engines that are knock-offs of the classic honda engines. Change the oil in em, clean the filter, and loctite the shit out of any nuts/bolts that come loose, and you can ride the piss out of them. Only issue I've had with mine is a leaky exhaust gasket. I just tell people it has a "performance" exhaust on it.
