Sorry, but this is flat-out incorrect.

Countersteer is the only way to turn a bicycle at speed. If you lean, you are simply inducing the bike to countersteer for you. The fact that you are not conscious of this act does not change the fact that it is happening regardless of your awareness.

More to the point, you cannot turn a bicycle at speed to the right by turning the handlebars to the right. The bicycle will go left, independent of your intentions.

Perhaps you meant to say that the only way to turn a bike in a particular direction involves countersteering. My scenario required no leaning.

If you are on a moving bike and you turn the handlebars to the right you will soon be on the ground. :) On a two wheeled vehicle the handlebars are used to adjust the angle of the bike/rider system with respect to the ground. The handlebars are not used for turning but for adjusting things so that a turn can occur. "Countersteering" is something that occurs at all times and in all situations. It has nothing special to do with turning.
