To ship would cost about $600 plus inport tax. The frame in the US for a 450r is roughly $700. I was quoted from one dealer here in the UK. £1000 plus postage.
The 700xx frame from a Honda dealer in the US is $1700. How much would you think a British dealer would charge me ,On similar lines to the 450r frame.
Even if it was £600 in postage,It is cheaper to buy from the US
