What is the technique of 'counterweighting' during slow, tight turns, and why is it used?

1. Lean your body in the opposite direction of the turn to help balance the motorcycle at low speeds.
2. Lean your body in the same direction as the turn to drag your knee on the pavement.
3. Move your body forward over the handlebars to keep the front tire firmly planted.
4. Shift your weight backward to increase rear wheel traction.
