Can be done easily. But there is a lot of work you must do first. (1) Contact the BMW dealer in Anchorage to make sure he'll have the hardware ready for you when you want it. Are you going to pay cash? (2) Find out from US Customs, if it is possible for non-resident aliens (I assume you carry a UK passport) to buy and register motorcycles in the US. (3)Check out shipping lines. Are you planning to ship to the UK or back to Alaska? If you're planning to ship to London, there is an economical way to ship by air from Ottawa, Canada, much cheaper than from the US. Have fun!
