Based on the Ural sT, the Solo X was a custom that you could order from James Loughead, the man behind Hammarhead Industries. Suggested price was $12,500. This example is claimed to have been built for Ewan McGregor, and it has just 200 miles.
It should be noted that it looks like Hammarhead went under and took some deposits with it, which is a huge shame. But I guess if you like the way this looks, you can now snag one without having to worry about if your bike will show up or not? The photos the seller included are kind of crap, so for better photos (and some more information on Hammarhead and this build), check out this profile on BikeEXIF.
