Suspension and cornering forces

The advantage from climbing over the bike to drag knee, elbow sliders and helmet on the ground is that the combined centre of gravity of the bike and rider moves inboard from the centre line of the bike.
The physics of the corner is based on that combined centre of gravity, so by hanging off the side, the bike is behaving as though it were more banked over than it actually is.
That gives less risk of running off the edge of the tyres.
It’s also giving the suspension more chance to move with bumps: think how the forks and steering react to a bump when leaning at 66 degrees!
