Where to find a sport bike in Shanghai?

[m55]

ETA: Hello to all the SH bikers!

I found the JLmoto shop, there hasn't been (from my search results on here) much of a mention of them/their reputation. I read that someone from their (Jimmy?) sold a couple of questionable bikes and didn't come through for the customers when it came time to their inspection thus costing a lot of money and headache for the buyers. Honest opinions appreciated here, I just want to get a good bike and enjoy riding on quiet days. JLmoto seemed to have a nice selection on their site but if they aren't being straight with customers I won't spend my time entertaining them.

Right now I have my Chinese license and am looking for a street bike, something like a 600+ Suzuki/Honda sport bike from the 90's/early 2000's would be ideal. I have budgeted to get an A-plate to avoid the headaches and stay on the right side of the law. If they retain their value I'll consider it a deposit (even if the selling prices are faintly ridiculous), if the rules change and they are worth a fraction of the current price I'll keep that in mind and enjoy every ride regardless

Anyway, if anyone has any recommendations for dealers of used bikes (websites/addresses/phone numbers) and places to keep clear of please feel free to post or PM.
