No matter what the EPA comes up with you'll still be able to go to your local big four motorcyle store and by a new bike for around 10 g's that will have a top speed in excess of 170 mph, do the quarter mile in under 10 sec, go 0 to 100 in under 6 sec, handle beautifully, and get 40+ mpg. All this while meeting EPA emission and noise restrictions. So what's the problem, clean air and less noise?
