You can organize a local Chinese drivers license - temporary permission to ride foreign motorcycles in Yinning. Motoexplorers organize this on the China Moto expeditions. You also need to have a raft of paperwork including clearance from ministry level in Beijing, entry permits for each Province, permission from Police & tourism authorities, army clearance, customs agents for entry & exit formalities (at each border crossing) as well as all hotel bookings, plus the Chinese driving license. If you wanted to get all formalities pre-cleared for you to ride across China, Motoexplorers would usually recommend starting to do this process about 5-6 months before arrival date - you could join in with a small group of riders also doing all of these formalities - saves money having to pay for all the guides, permits, vehicle etc alone, get Motoexplorers to do all the paperwork and organising; http://www.motoexplorers.co.uk then you can ride on your own, at your own pace each day across china. Usually permissions are granted for 30 days to explore China. You have to nominate an exit port, somewhere like a sea-freight port near Beijing, or better still exit by land crossing the border to Laos - nicer routes and easier formalities for border paperwork. Then a nice ride through Laos to Thailand and from Bangkok you can ride freely or freight your bike anywhere in the World.
