1. The Torso-Arms-Handlebar steering theory:

 Since the 'celerifere' and the 'draisienne', millions of people have imagined theories explaining the stability and steering of 2-Wheelers.

But somehow, even the well known 2-Wheeler steering theories (Counter-steering, Gyroscopic reactions, Front fork geometry ...) have limits that support misunderstandings. They do not bring up a consensus among cyclists and even scientific background people. And this doesn't help avoid motorcycle accidents.

The new steering theory explained on this site does not contradict the contribution of these other known theories, but:

  1. It completes them and puts them in perspective, to explain better how motorcycles and bicycles stay upright and ride so well.
  2. It improves the countersteering technique and increases steering precision and riding safety.
  3. And it helps analyze and develop safer and more comfortable motorcycle concepts.

This theory is based on the Torso-Arms-Handlebar mechanism, hence the theory's name. Click on the following links to know more:
