I'm not completely sure, but I believe Euro III environmental restrictions are already tougher than that of the CA/EPA regulations. Several bike companies already sell bikes here in the states that mee or exceed Euro III regs (mostly Euro bikes, natch), and the Japanese builders make bikes that meet them (of course, or there wouldn;t be any Euro-specced bikes).
I don't see the new regs being as detrimental or neutering as people would like to believe.
