I took my 2010 Ural Cross from the UK to the Eastern side of Mongolia and back in 7 weeks. The Cross isn't available in the States but I would have been happier with a Gear-up! The Russian bits were fine but the Slovakian made sidecar sub-chassis broke!
It's all documented HERE
Click on Mongolia and then Diary.
I would have another in a heartbeat and to that end I've written to Ural in America to ask if I could hire any model to tour around the States in 2014. This year I'm away around the World but on a solo. No reflection on the Ural but it would be too expensive to ship across the Pacific and Atlantic.
