A lot of the reason, that we are not getting the bikes the original poster asked about is because of this ..... http://www.epa.gov/otaq/roadbike.htm If you want to either get sick or fall a sleep that is a good read :huh It is simply about money, you cannot spend millions trying to satisfy the US government requirements for maybe 1000 bikes sold. Back in the late 90's I had dinner and drinks with some big shots from a european car manufacturer. I had asked them about why they had put power windows on a special lightweight street legal track day car they were premiering. They told me that if they had put in manual windows it was enough of a change that they would have to re certify the car for the US market. Thats 3 cars for crash testing +all the other certifications required to sell here.
