Your better off just buying a US bike and ordering the Black/Black fairings.
You will have to change a lot more than the headlight bringing a UK bike into the states.
Even if you get a Canadian bike, you will still have to change the speedo, etc..... that is if your local DMV accepts the Canadian paperwork. I had a hell of a time getting mine titled/licensed. Something you want to check into. Since 9/11 Suzuki now charges you $1k for a Man. proof of Vin.
You can do either one but I would rather spend $1500 on a US spec bike to have Black than $2k on paperwork and changes to get a UK bike legal. That's not counting if customs lets it through or down time waiting for your paperwork to be finished SO YOU CAN RIDE IT.
There is a lot more involved than you think.
