Hello Russ and welcome from Virginia. My 2014 R3T is the first bike of 28 that I have ridden that has ABS. I have successfully used it a few times. The most dramatic was a freeway emergency stop from 85 MPH on I-95 north here in VA. The two cars directly ahead of me were spinning out of control after one merged into the front of the other. I had no escape left or right and the ABS allowed me to maneuver with grace while my adrenaline over powered my system. I can't tell you how far I went before stopping, but it was very controlled and safe and I was honking on both brakes with all my might.
I have nearly 35K miles on the bike now and it has never let me down out on the highway. I might complain about the battery failing at 6F, but that is fixed with a new battery which goes in later this week. Good luck!
