its to help aid throttle control and prevent wheel spin. it has its pro's and cons.

pro's: if setting in mode b or c, it will help reduce wheel spin by changing the ecm kinda like putting a governor on the bike

cons: it doesnt teach you anything. if you learn to rely on the selector, you will never learn what to do if a wheel spin occurs. it teachs you nothing about throttle control.


I really dont see it being useful on the streets. theres too many other factors that could play into a situation. debris(rocks, leaves), uneven road surface, other vehicles, oily surfaces, etc.
