If this bike is made registerable in China then I'd think it would be a huge breakthrough for the legalization of large engine motorcycles in China... imagine that.
I love my current bike but I also crave something bigger; a 600 would be just right. If it turns out to be a fairly reliable machine with easy access to spare parts then it would be so attractive, although, if this does become registerable all over China then why not a Honda, a Yamaha or another well-known foreign make 600cc bike? Would they still outlaw the other brands and say "Chinese motorbikes only!"
