And the reason why you lean, instead of simply steering to the left or right, when you countersteer is because, as you are fighting the bars to turn the handlebars, the force that is directed against the front wheel ... twists because of gyroscopic forces. Those same forces also stabilizes the new, not quite vertical, and (hopefully) not quite horizontal, orientation of you and your bike while you are banked over.
