Wishing you the best of luck on your purchase. I think the QingQi is better suited for rough roads, but tokyokid swears by the Yamaha, so I don't think you will go wrong with the YBR either. As you said, probably comes down to which shop gives you the best deal. Both of these bikes will get you there, but you're trip is going to knock a serious chunk out of their life spans. My big hang up with the YBR is the 18" tires and the tiny 125 motor. The QingQi has standard 18/21" tires (very easy to find) and these handle much better in the dirt and gravel.

I guess what you want is a QingQi 200 for the ride to Europe, and a YBR125 once you get there .

Cheers!
