Insurance. My experience is that US insurers won't touch anything in Europe - you'll need "Green Card" 3rd Party Liability insurance - available from a number of sources. You will need this to be in effect before they will let your bike out of Customs. If you find a US insurer that will extend their coverage to Europe, please let me know. Green Card was €20/month in 2009. It's gone up somewhat since then. Breakdown. I have ADAC Plus - but then, my bike is stored with Stefan Knopf in Heidelberg, and he lets me use his address as the return point. Not sure what you'd do without a fixed location. Sorry. Also consider a medical air evacuation policy. I use MedJet Express. While I (thankfully) haven't had to use their services, I know people who have and they're very happy with the service.
