I’m looking for the exact same information. Here is what I have found out so far.

You’ll need Green Card Insurance. Its insurance for your bike in Europe most port customs offices sell it. For one month it runs around $120 - $150. But that’s only one way coverage. I’m still looking for full coverage. As soon as I find something I’ll let you know. I found one company here in the US but they won’t have any pricing for another month. They are finalizing the contracts with the main insurance company. I would like to have that in hand before I leave the US.

You don’t need any special driver license in Europe. You can ride on your regular US license.

You need to bring your registration and title with you.

I have a company that can sea fright the bike from NYC to German for $350. But when I called the company from whom I would be picking up the bike in German from they told me that I’ll have to leave a 25% of the value of the bike as a deposit. It’s a deposit of VAT and other government taxes in case I sell the bike. Once I send it back to US they refund it. This I have not yet confirmed. I have heard that this deposit is not required. I’ also looking into air fright. I just came across this site Warren Motorcycle Transport www.gate.net. I’m considering spending the extra money and shipping it by air. Also I’m still researching shipping options and cost of the return trip back to the US.

This is all the info I have gathered so far, hope its a little helpful.
