I think that is an over simplification of ABS. Race bikes have ABS these days and they use it in the wet and the dry. what ABS does is make really good stops in all sorts of situations. Do you need it? Maybe, but its better at stopping than we are over 10 stops, and its going to keep getting better.
The ABS system on a $1,000,000 MotoGP bike
is not the same as you will find on a Hayabusa.
Many of today's racers would prefer to turn
off the traction control, ABS, telemetry, etc etc...and just race.
