Like the ABS that come on many motorcycles, ABS Pro is a safety feature, not a performance enhancement. I think that everyone should be aware that while ABS Pro makes braking in a corner safer, it does not guarantee that you can grab a handful of brakes and not crash. Whatever degree of safety that it might provide for normal street riding, it is not recommended for use on the track.
ABS Pro is no substitute for proper cornering technique. It will not protect you much from pushing your bike too hard into a corner or from the consequences of riding recklessly on roads where you are likely to encounter road obstructions, wildlife, stopped tourists, etc. The worst case would be for a rider to develop a false sense of security and wreck making a turn that he would have never tried without ABS Pro.
Would I object to having ABS Pro on my 2015 R1200R? No. I like safety technologies. Would I sell my 2015 without ABS Pro and buy a 2017 R1200R with it? No! If a retrofit were offered at a reasonable price, I would not object to adding it to my motorcycle. However, I would not pay $1,500 for the upgrade; it just would not be worth it to me.
I think that you have to evaluate your riding style and the issues that you have had in the past with braking in corners. I came to BWM in 2015 from the Harley Davidson community where we were all used to riding heavier, less responsive motorcycles that did not have ABS. The advantage of that is that you have to learn how to set up a for a turn, how to ride with a safety margin in turns, and how to brake in a turn safely if the need were to arise.
One of the best braking techniques is to ride a line that will let you get the bike upright and brake really hard, as opposed to braking mildly while remaining leaned over. A late apex turn, where you brake effectively going into the turn, with the intent of accelerating out the turn, gives you a straighter line through the turn. But you can't use that technique on every turn, unfortunately.
Nothing heard yet. I have a friend who's waiting for it before committing to an RS. He reckons he needs all the help he can get!
