Motorthings- I realize that others in this thread said that countersteering doesn't work. I am not one of those people.
It definitely does work at any speed above ~5mph.
I wasn't trying to create an argument that body steering is superior. You are reading that in through either your own prior experience and knowledge. I'm saying that it is exists and is more significant on a bicycle than a motorcycle. As in, can be and is used on a bicycle, and useless as you say on a motorcycle. (Shifting your weight/CG on a motorcycle does work, and that's not what we are talking about.)
I did not teach at Keith Code's school but I've spent a good amount of time on motorcycles. I'm not arguing with you about motorcycles. I think this discussion is most relevant when left to bicycles, though.
