Jan - Sept 2002 I drove on a KLR from Dallas to LA to Inuvik. Met some incredible Transalp people who helped me on my way even putting me up for a few nights.
There appears to be a strong online TransAlp community in the USA see http://www.thetransalp.com/index.html
There's a forum there somewhere that you can mention your impending trip. I'm confident you'll get more than one reply of welcome to the US.
I think the US Transalp community is strong as the bike was only imported there for a limited time. So they've got to rely on themselves in terms of support and information.
(but this site going down in 2 weeks time!)
PS: I bought my bike in Texas and got insurance from Progressive (they have a website) for about $450 for the year with a pro rata refund. I had to give a US address but they took my Irish drivers license (didnt even ask for the International one - nor did the cops when I went thru a red light). So not sure if Progressive will do it for a UK reg, but I guess there's no harm in asking them - or asking for what they would otherwise recommend. You can query them by email too - response seems to take about 2-3 days or so. But they're on the ball. Good luck
