Hi. No luck for insurance from most USA insurance companies. First they did not want to insure my bike becuase I had no local adress, secondly my bike was not a model sold in the USA (confirmed by Chassis no).
Only company that helped me was Fernet insurance. They were helpfull. I spoke to a lady with the name of Phyllis, she arranged everything for me via email. her mail is at firstname.lastname@example.org
The documents got mailed to me, I printed it out and it was good enough for the few times I was asked for it. It also covered Canada (asked for it) It was valid for 59 days, and you can renew it. Cant remember the price, but was more than $100 I think.
Got this info from earlier posts on this Forum.
PS: Bike is a ZA regestration, but should be the same for EU
