| Agree with the bumps in the braking area, but the forces acting on the spring under heavy braking are dominated by the sprung weight, not the unsprung weight. That is when the springs are that far compressed, essentially identical to a huge amount of spring preload, it makes little difference if the unsprung weight is slightly less. The reduction of unsprung weight is most noticable when the bike is balanced on its suspension, i.e. not fully compressed on either end. The reduction of unsprung weight allows the tyre to follow the road contour better, that is is doesn't jump over the bumps.
Still can't see spring changes due to slightly less unsprung weight.
