ABS is great for those moments when a caged monkey decides to want your lane at a moments notice.
ABS/TCS is not good for when you're at a 60° incline, they both activate and you go sliding down the hill lol.
It takes a lot to activate the ABS on these bikes, didn't feel it once on the track, but it's a great peace of mind to know that if there is a potential phuck up you're not going to squabble away.
