It should be simple, if you like the Wuyang Honda, which have a good reputation btw, go to the dealers and pay a deposit of around 500 or so. Make sure they understand that you will pay the remainder before you take full possession of a fully registered bike. You can register it in your name as you have a residence permit, although this is more complex than simply registering the bike in the name of someone you trust with a Chinese ID card, still perfectly legal, although the Chinese person is technically the owner, so some people are uncomfortable with this.

About the license, the foreign affairs office should be able to translate your home license into Chinese for a fee of around 200. Then eye test and police photo at a police traffic center of some kind. Then the 100 question multiple choice test. You could come into difficulties if the local Gong An refuse to transfer your license for some reason (which may be the case where you are due to local motorcycle bans) and another district may be unable to do it for you as you are not registered as living locally.

Being fully legal is ideal, the next best is being as legal as you can be!
