I've come across a pretty good deal (asking 3000rmb) on a lightly used CQR250 with the Zhongshan air-cooled engine. I've been looking for something to use as a light commuter bike and general exploring bike. Is this worth it?

The bike never had plates on it. Will it be difficult to get them? I'm in Shanghai, but I don't need the expensive one to ride downtown, just something that to ride out of town legally.

Thanks,
Paul
