Might this be our love of the newfound stupid electronics !

Is the whole idea behind ABS NOT to lock up ?

That it is !  However bar for help with stupid brake grabbing it does not help brake performance for a most semi skilled riders!

Just a possible scenario.

He didn't maybe still have his ABS disabled because he rode gravel earlier and then maybe just maybe he has some kind of epileptic fit. My dad gets those and it would explain the scenario perfectly.

I would be very keen to see how this gets investigated. 1st time I hear of anything like this on a DCT Twin. I'm sure we would like to know if it was strictly mechanical.

I'm under correction but you cant disable the ABS on the front, just the back.

You are right. Seems like you can only turn off the rear ABS.

Correct, only the rear disables via the button.
Would be interesting to know why this happened. First time I have heard of this on a AT

This is the only picture of the fall I could get so far, note where the skid mark starts, open straight road!!
What bothers me about this photo is that this is a very big fat skid mark for a front tyre?

Also ABS failure on AT, but really can't find a lot on the topic on the net...it's not a common issue on them it seems.

Something else went wrong here.

ABS cannot apply pressure to the brakes without pressure from user input. It can only reduce/modulate this pressure.

It starts thin and as the wheel started skidding it turned sideways from the marks, then the rest of the bike made contact.

My theory is mud played a part and perhaps a big rock was stuck in the accumulated debris, on the tar it dislodged and jammed the tyre?

I sent Gary a WhatsApp, in due time when he feels strong enough, he will let the forum know in his own words what transpired that day. He certainly is a very competent and able rider which I don't question at all.
In hindsight, I'm sure he will be skeptical to ride the bike again until a concrete answer can be given as to what went wrong here..

If i had to explain you would not understand anyway......
