2.4 Prediction of the lean angles in a steady state curve:

The Torso-Arms-Handlebar theory predicts that in the third step when going into a turn, the 2-Wheeler leans further than the rider’s torso.Slow motion images can again confirm this unexpected (or at least unexplained) phenomenon, in a steady state curve. As can be seen, the chassis white line leans more than the torso red line:

 

 

Independent motorcycle magazines show lots of motorcycles leaning more than the rider’s torso.
Thanks here to Turbo-Press Inc. publishing Cycle Canada, Moto Journal and Le Motocycliste, for the following photos.

 

The next three photos clearly show a motorcycle in a long and relatively steady curve. The enlargement to the right clearly shows again the chassis white line leaning more than the torso red line:
