OK, those in China could check this company out. I don't know if they are affiliated with Galaxy, but they do seem to be the manufacturer for Pitster Pro's bikes, and have the Loncin water-cooled engine version of the XTR250 bike, but don't know if they could sell to you guys in China. If anyone's nearby, contact them and see what they have to say.
