I just found out why Suzuki put the mode selector on these bikes, after talking to one of the factory designers. This is what he said.
A - Mode, the mode the bike wakes up in, with no restriction.
B - Mode, if you are riding with a new ZX14, to make sure it is not left behind.
C - Mode, specially programmed so a Gen1 Busa will keep up with the Gen2, also known as "Gentleman's Mode"
