shipping USA > Europe
I've just shipped my bike back from Spain to Boston with Chris.
He will give you a quote based on crate volume so the smaller the crate, the cheaper it will be.
The bike was shipped door to door so I paid extra for that.
It was picked up in southern Spain Dec 2nd arrived at my house in Boston Feb 8th.
Cost was £1,300.00 AND I had to crate it. If I had arranged it to be shipped from UK, it would have been around £1,000.00 and even cheaper if I had not had it delivered to my house. You also might get a deal if you plan a round trip for you bike and you could use the same crate!
If you're only going for a month, there is a company in Long Island NY I used that provided motorcycle travel insurance as long as you have a valid registration...I can find out the name of the company if you need it. Would involve digging out some old paper work.
Your US driving license is valid over there. Also, any tickets you may pick up will not be processed due to international complications...at least in the UK which is speed camera central. Not that you'll be going over the limit of course! :>)
best of luck with your trip
