Worst thing you have to worry about on bringing any kind of motorized vehicle. Bringing it isnt that bad, the cost of making it pass US DOT standards is what could cost you the most. Emissions, lighting as stated above. Shouldnt cost you much more then $1000 US to have it shipped, cause of its size and weight. So do you think it is worth keeping, or can you sell it and get enough to buy what you want here?
