I have an unlinked 2009 ABS, and just love the rear brake set up,and always use it in the down hill twisties. You can stomp on it full force with confidence of no lockup or high side, and it scrubs off just enough enertia and loads the front forks down beautifully for the next corner turn in. In fact I use very little front brake in the California mountains, just when needed.
ABS unlinked is much better than linked. But why would one "stomp" on a brake? Sadly no one really knows how to brake properly anymore. They just stomp. That is what technology has done to us, made us lose skills. In right at about 1 million miles in cars, most of which were in cars, trucks and vans with no ABS, only my current car has ABS, all the others did not. So at this point, about 950,000 miles with no ABS, and no incidents related to not having ABS, in snow, on ice, rain, etc. My issue now, is the ABS will not let me stop on some of the hills around here when it is snowy and icy, the ABS cycles as I try to stop at the stop sign at the bottom of a hill, causing the vehicle to keep going and not stop. MY non-ABS vehicle, which sadly I do not have now, would stop perfectly, because at some point, in order to stop, the wheels actually have to stop turning. The ABS on both of my vehicles have trouble with that on really bad roads. It's ridiculous. I can sometimes get it to stop on these roads using the parking brake, thankfully cable operated, but being on the rear brake, that isn't always effective.
As for motorcycles, ABS is a great thing, don't get me wrong, but you can ride a motorcycle safely without it, and use the rear brake effectively. I use both brakes. I also practice emergency braking, so I can brake when needed, without problems. I will not deny the effectiveness of ABS on a motorcycle, and its effects on safety, but You don't need to to ride safely, and you can safely use the rear brake on a non-ABS motorcycle. As someone who has ridden for 40 years on the street I think the thought you cannot use the rear brake safely on a non-ABS bike to be ridiculous. Thank God I survived all these years with such an unsafe system.
Sorry, I just get tired of the alarmist attitude towards ABS vs non-ABS. The issue today is, everybody lets the car/bike do the work for them, in cars they become passengers instead of actual alert drivers, I fear the same is happening for motorcyclists as well.
