I just found this nifty blog (update - the blog is now defunct) written by a Ural enthusiast. There are only a couple things keeping me from getting a Ural:
I have too many motorcycles already
I don't have the money for yet another motorcycle
No one makes a super-soaker mount for the sidecar yet
If Lady Luck and I ever move somewhere that gets a lot of snow and ice, I'll probably get one for the winter months. I don't know for sure, but something tells me the Triumph would not get along with ice or snow. Not at all.
