I realize that this is a rather old thread, but having just ridden a stretch of dirt road between Tortilla Flat and Roosevelt Lake east of Phoenix, I have some observations. Prior to this ride, I was one who considered the potential of being able to disable the ABS unnecessary and probably not a good idea. I can tell you on at least two occasions, while on a downhill and approaching a curve and finding the need to slow to avoid missing the curve and slamming into a rock wall, that i had no brakes. I was riding with a friend who had an 07 non ABS, and he had no issue whatsoever. Based on my experience, I am convinced that there are some conditions where the interaction between road surface and the ABS render the bike literally brakeless. I will never ride that road again without having first installed an Eager Beaver ABS bypass, or something similar.
