Thanks ZMC, for the advice on the paperwork that needs to come with the bike. Will obviously help when I get pulled over. I will visit Shenzhen to get the bike.
1000 yuan is not too much to lose on resale. Plus someone will get lucky and get a really cheap bike.
:Beach: I will have the first week to soak up Hong Kong - work related. The second week I want to see as much as possible , real world - not the normal tourist traps. Seven days should be good for 1000 miles round trip.

JHMM,

I would forget Shenzhen and Guangzhou, the streets are pretty much swept clean of motorcycles these days, hardly any shops left. Try some of the smaller cities a little to the north, where bikes have not been banned. It's a better place to start your trip from and much easier to avoid "hassles".

Good luck with your adventure.

Cheers
