China-Pakistan via the Karakoram Hwy. question

Hello. I would like some advise on a trip I am planning. I am currently traveling in China and thought of buying a motorbike to tour around and then ride the Karakoram to Pakistan. I do have some questions and any advise or help is greatly appreciated.
- what's the process to purchase a motorbike in china regarding ownership/licensing etc
- what should i expect to spend for a motorbike here in china.
- The big question- what documentation would i need to successfully cross the bordern into Pakistan.

Any other advise regarding my plans is welcome. Thanks, Bosco

For one and two, please check other posts on the forum.

For the big question, the problem is making it past the Tashkorgan check point without an escort. If you're going through the border, it shouldn't be as difficult but you will need a visa or whatever doc you need for entering Pakistan.

Might be difficult to get the bike through Chinese customs as the bike probably won't be registered in his name.
