2.5 Increased steering swiftness and sensitivity with speed:

Centrifugal forces control the 2-Wheeler leaning angle through the Torso-Arms-Handlebar mechanism. Thus, the higher the speed gets, the stronger the centrifugal forces also get to correct even faster the 2-Wheeler lean angles so that it can follow faster the rider’s torso lean angle.

This explains why we only have to 'think' of leaning and the 2-Wheeler already follows, even though the rider is not acting faster on the handlebar.

So, the Torso-Arms-Handlebar theory explains the feeling of the motorcycle almost being 'part of your body' at high speeds.

In reality, there always is a certain amount of error between the torso leaning and the motorcycle leaning, but it is small enough not to be felt, just like the error between the steering wheel and the front wheel, in the case of a car power steering.
