You're much better off to buy a UK plated Harley than a US one.... for some reason importing a US Harley presents a lot more issues - We're bikers (and indeed have a Harley for sale.... ) We know a lot of bikers in the area and also the mechanics, a very good friend of ours runs M&M Custom in Altea, who build custom bikes and maintain bikes in general (usually Harleys or other cruisers), and they always try to stay away from the Us imports.

I can try and find out more info if you need it, let me know.
