Nice link SB. I get it. ABS = good. I owned and rode one of the Harleys equipped with ABS and can say that it responded well to emergency stops but was less than impressive under non-emergency conditions. I don't know how it is around you but around here there are stop signs out in the country with rumble strips in front of them to wake up a rider/driver. Whenever I stopped at one of those on my HD I got to feel the ABS preventing me stopping right. That is right. It interfered with my braking and tried to send me right through the stop sign without letting me stop. It seems that the software was reading the peaks and valleys of wheel speed as a loss of traction so it removed braking forces from my wheels. I came way too close to going through those stop signs without stopping to suit me.
I much prefer the ABS on my Vision that lets me actually stop on those rumble strips. It probably works almost as well in an emergency stop as the HD one but does not give false "locked wheel" signals to the ABS computer.

I like my ABS for when I'm on a gravelly road or anything with a loose surface. However, sometimes it gets a false trigger if I am coming to a stop and the front wheel hits a joint or some other small bump. I'm used to it now, but I definitely notice it.

You fellas ought to tread lightly. The ABS Holy Mother Saints Preservation Society might get all squinty eyed and overchurn the butter and all kinds of calamitous racket if there's too much of an undercurrent of less than complete submission.

I remember when I wondered aloud about removing the ABS decal from my side cover. I was chopped into little pieces with a axe and fed to the pigs. It wasn't pretty. I have learned to know my place.

I bet it would stop faster if the wheel was left locked.

It may keep you up right... At least till you hit what ever it is your panic braking for....

Also notice how much shorter the stop is with ABS... Because they are using the front brake. But not using the front brake when they say the ABS is no active.....

I agree.

I also have a BMW - THEY know how to do ABS. The BMW system is VASTLY superior to the Victory system.

As Pop alluded to, it's a pitch from HD for ABS. Interestingly enough the Motorcycle Safety Foundation in their classes trains riders to deal with rear and front wheel lock ups without ABS.

The manufacturers simply install ABS to make up for the lack of training that the majority of riders have. It's a good thing but there's no substitute for proper training in crash avoidance. I've said before and I will repeat myself, if you haven't taken an MSF rider safety course (beginner or advanced) do so. You will be AMAZED at what you take away from the course no matter your experience level.

Watch it again, they are clearly using the front brake for both stops. Rear brake only would not cause that much front end dive. As for letting it slide sideways, meh, that's probably just done for dramatic effect. I'm not saying it's not setup, I'm just saying that basic appearances do show similar, if not the same braking conditions.

My theory on the sliding sideways bit is that the front wheel tucked in the gravel causing the bike to fall on the outrigger. Had the bike not had the outrigger, the rider would have bitten the pavement about 2 nanoseconds after that tire tucked. Been there, done that.

Since the outrigger kept him up, he just maintained brake pressure allowing the bike to flail around for effect as you say.

The ABS tire doesn't tuck.

I don't care if you take classes til the cows come home, if you get on the front brakes and that tire tucks on a low traction surface in an emergency stop, there is a very real chance you're gonna fall on your face. That's not a knock on classes. I think learning and practicing techniques are a great use of our time, but it would get awfully expensive having people practice how not to wreck in such situations. I'm not sure given human reaction times that it's even possible.

I haven't test the Vic ABS in poor traction conditions. I have tested a bunch of others and they all seemed to work well to me.
