When you go around a turn to your left, centrifugal forces want to stand the bike up, and fling it off to the right. Your body weight is what keeps it down. Think of it as a tug of war against the centrifugal forces as essentially controlled by the throttle. The more you are leaned inside against these forces with your weight, the harder you can theoretically crank on the throttle without the bike actually standing up, and you flying up and over to the right.

Just like in a tug of war with a rope, you lean away from the pull of the forces by increasing your angle relative to your inside most contact [fulcrum] point (in this case your inside footpeg) to maximize the effectiveness of your weight.

In other words, the harder you're tugging that shit down towards the inside, the harder you can crank on the gas, and the faster you can go through the turn, the limiting factors then being essentially tire contact and adhesion.

Yes, the more you hang off that shit like a desperate tug-of-war participant, the faster you can go, all other things being equal.

Keeping the weight bias forward is essential if the bike is understeering, and when on throttle for exit, it will keep the back more tucked in. It's not so much one position, as a smooth arc motion. Lead with your forehead.
