We haven't had to show our motorcycle license at all so far in Kazakhstan or in Kyrgyzstan, but then again we haven't gotten stopped by cops (fingers crossed). At the border so far they have asked only for the blue book - they have no idea what it says of course since it's in Chinese, but we tell them the information they need.

I actually used a fourth method that I didn't mention on the blog, I'll PM you

Cheers, J
