2.3 Slow motion images when going into a turn at slow speed:
Slow motion images show that when going into a turn at slow speed, countersteering exists even though it's often taught in motorcycle riding courses that it doesn’t. These images can further confirm the three steps predicted by the Torso-Arms-Handlebar theory when going into such a turn: Step 1: The torso suddenly leans to the right so that the Torso-Arms-Handlebar mechanism steers the front wheel towards the left (white arrow bottom left). This generates a centrifugal force (red arrow) that pushes the 2-Wheeler towards the right in order to go into the turn. Step 2: The front wheel is oriented straight ahead and no centrifugal force is generated to hold-up the 2-Wheeler that keeps on falling to the right. Step 3: The 2-Wheeler leans further than the rider’s torso (The camera angle does not show this clearly here), which steers the front wheel towards the right throught the Torso-Arms-Handlebar mechanism, without the rider having turned the handlebar consciously.
