Not sure I understand how counter steering figures into this equation, especially since there are so many definitions of countersteer. Countersteer in a skid/drift or countersteer by push left to go left?
I guess the latter, if there's really a difference. Suppose you're stopped, engine running and in gear, and you intentionally lean the bike to the right. Now, for some reason, you can't stand the bike back up. If you twist the front wheel to the right and move forward, the front wheel moves to the right, under the weight, and the bike straightens up.
To me, that's the exact same action as seen during the transition in the middle of a right-to-left S-curve. The bike is leaning to the right, and you apply torque to the handle-bars, steering the front wheel to the right which moves it under the mass (center of gravity) on the way to being to the right of the COG, where the bike then leans to the left.
Now, say you're slowing to a stop under the same circumstance, leaning (and slowly turning) to the right. As you stop, if you maintain the lean, the bike wants to fall to the right. If you steer the front wheel under the COG as you stop, the lean disappears. We do this as we stop when not leaning, to create a slight lean to put only one foot down.
Hving the tires back under the center of mass before stopping can be more easily described as not coming to a stop while leaned over, ie in a corner. IMHO
Technically the same thing, one in laymen terms, one in scientific connotation. Tires under center of mass requires minimal leg muscle activation and exertion to maintain equilibrium resulting in an upright stature while making zero forward progress.
Exactly. Every rider counter-steers, consciously or not, even on a bicycle. Doing it intentionally allows us to isolate steering and leaning. When you see a road racer hanging off to the inside of a turn at speed, he's actually using "counter-counter-steering" to keep the bike from leaning as far as the placement of the COG alone would otherwise cause it to lean.
Those riders who are unaware control steering with leaning, while those who are aware control leaning with steering. If you intentionally lean your body to one side, you must counter-steer to ride straight. Try that next time you're on the bike. Ride down a straight road, lean your body to one side, and note the twist required to keep going in a straight line.
