ummm, actually all turns are initiated by a counter-steer. Except maybe those wobble turns at low speed, like barely moving. On some bikes the counter-steer is so brief, it's just not visible or recognizable. If you don't believe in counter-steer, try turning with one hand, and see whether you pull or push to turn. The main reason is that the counter-steer can be initiated with a shift in body weight. Although there are studies done that dispute the use of body mass to do anything much at all in turning. Those studies took the clip-ons off and mounted them to the frame. Most riders could not turn without extreme effort. And the turns were shallow and difficult with body mass only. I disagree with some of that study, it seems to me that riding with no hands, and steering with body mass only, pretty much makes a solid point for the case. Best done on a bicycle, which weighs a lot less.
