With the broom you move your hand around under it to get the broom's CG centered back on your hand. For that to work on a motorcycle you would need to move the entire front tire left or right out from under the motorcycle the same way you move your hand under the broom
(there is actually an RC bike that steers this way). On a motorcycle the front tire simply turns, it doesn't move relative to the frame other than the tiny amount caused by rake angles.
That is EXACTLY why we countersteer, because we are moving and the front tire does not slide sideways. But if we could make the front tire slide sideways as we are moving, lets say we push a button and the tire slide to the left from under us, we would then lean right, and hence turn right, and guess what, in that case we would not need to counter steer! Like the broom example. But since the tire does not move that way, it rolls, then we need to countersteer to move it to the side, in our example to the left, creating the appropriate "unbalance" that will generate the lean to the right and we will turn to the right. It is a very simple concept. Like the broom example.
