I was living in Germany when I wanted to buy a US spec MV Agusta (made in Italy) in 2007. For one, the US price was thousands less than the Euro price (wasn't just a currency conversion issue...things just cost more there). Also, in order to have a US warranty, the bike had to be delivered in the US first, then shipped to me in Germany. I paid for the shipping which wasn't too bad. In short, MV wouldn't sell me a US spec bike and deliver to Germany. Also in order for my US dealer to ship to me in Germany, MV made me sign a statement saying I would not sell the bike in Europe. i could have have sold it the day I got it and profited thousands. Still have the bike!!
So my thoughts are if you wanted to have RHD, you're not going to have a US warranty as it'll be warrantied where first delivered.
