From what I understand it's supposed to kill "stoppies" and wheelies - the sensors compare the wheels speeds and if the front slows way more than the rear the electronic nanny's get to work. But I think that's with all the traction aids turned on. There's a special plug accessed underneath the seat that when plugged in, accesses Race mode that either turns everything off or gives you the option to, not sure. Why you'd want to do that on a 200hp bike is beyond me. Oh yeah now I remember, insane stunts.
