Embedding will kill my link to a specific time, but this proves that leaning can steer a bike with no handlebar inputs... at least, it can when wheelieing:

The thing to remember is that the tires are like any gyroscope and they will stay at the angle you set them at as long as they are spinning with enough force until you apply inputs to change that. You do that with counter-steering. The turn itself comes from the differing surface area from the inner diameter and the outer diameter of a round tire, kinda like a typical wider-at-the-top drinking glass or cone will roll in a circle. You only need enough bar input to change the lean angle and then it is all about maintaining gyroscopic force by rolling on the throttle.

The "No BS bike" with the dual bars shows that it's nearly impossible to do these kind of turns without counter-steering but that's mostly because you have two tires and the forward direction keeps straightening the front in line with the rear. The best you can do at any normal speed is change lanes... slowly.
