Has been posted before but this google video is an example of bike control including some tight counter steering.

Went from pushing the bars to the side whilst shifting weight to countersteer to keeping arms horizontal and pushing forwards instead. First time I tried it at 60 mph on a left hander and the Bike almost ended up in the field as I wasn't ready for the greater degree of turning it gave..

This is how I see it.
Keith code has proved with his no-body-steer bike that it's not possible to turn a bike without turning the steering. It cannot be done by shifting body weight alone.
Sir Isaac Newton's law states that every action must have an equal and opposite reaction. And that a body will remain in a state of constant motion unless acted on by some other external force.
Now if you are going dead ahead, in a bolt-upright position, you have to turn the bars to initiate any turn, however small an amount (as proved by Keith Code). So you make a tiny turn to the right, and now your bike is leaning left, because the bike has rotated around it's centre of mass aligned along the direction of travel (newton's law). Now your centre of gravity has shifted to the left of directly above the wheel centreline and gravity is starting to pull you over. Your only recourse to stop yourself toppling is to steer to the left. In effect, you have initiated a left-turn by using a right turn i.e. countersteering.
I believe that people think they can turn a bike without countersteering because the forces required to initiate a low-speed turn as so very small they simply don't notice them.
As an example, if you tried to stand a sportsbike up on it's fully-inflated tyres wthout falling over, you would find it impossible, but theoretically it IS possible if you could find the perfect balancing point. You could try for hours and perhaps get it standing for a few seconds but eventually it will fall over, so small is the force required to unbalance it. When you are moving slowly you have so little rotating inertia forces (the wheels turning) to stabilise the bike that you need only the tiniest infintessimal amount of countersteer to shift the center-of-mass and initiate a turn, that people think it's not necessary. |
