Now up: 2012 Honda CB1100 - A very special section on TMW

I don't know see how 60kmph and 80mph (129 kmph) are even remotely similar or comparable. In fact your statement actually strengthens the argument of bikes getting the best gas mileage at 60 kmph constant.

I cant really think of anywhere that you would ride at 60kmph constantly, at least in north america. 60kmph speed limit would be a city street so you would be mostly in stop and go traffic. A tighter section of a backroad maybe (though even there the speed limts are usually around 55-65mph)

I never said anything about riding at 60kmph being practical or even desirable. I just stated that that is the speed that most bikes get the best gas mileage.
