So with ABS you have to completely rethink emergency braking. For years you have trained your self to push the brakes and 'feel' the bike so you don't slide. You now do it without thinking, it is instinct. With ABS, in a panic/emergency stop that needs to change. You jam both of them on as hard as you can and let the computer take care of business. You will stop MUCH faster.
So, if you didn't feel the ABS kick in, you were not stopping as fast as you could have. Obviously it worked out fine, but maybe next time it wont. Go out and practice. You will be amazed how much faster you can stop. In fact test it. Hit a speed and pick a marker on the side of the road and do your usual instinct stop. Then go back and do it my way.
