I've heard people say that you can tell when the ABS is activated on a bike equipped with it, but today I experienced it. I was riding home from Malibu down PCH, and traffic slowed because there was an accident. I was passing the accident and looked to my right at a woman who was sitting on the ground (she was involved in the accident) and then when I looked back in front of me, a truck had stopped. I grabbed the front brake and stopped just short of the truck. The feeling is a very distinct vibration, almost like your riding over evenly spaced bumps, and I think it even made a sound like that too, it happened so fast. I've braked hard in the past, but this is definitely my first time activating the ABS. I can definitely say I'm glad I made the investment.
