Fallwew, in some way you should be happy your trip came to an end in China. The roads in China are so heavenly compared to the ones in Kazakhstan. Were doing a similar kind of trip now, but then on a YBR250. My guess is that the suspension is alot looser than on your gsxr, I could never imagine driving on kazakh roads with your bike. We are breaking our backs already, doing 50 kmh, on the national highways!
Anyway Im glad your doing fine now and hope some day youll be able to do the trip. Good luck!
