I wonder if the same care at the same level is required for an ABS + Trac Control bike.
ABS and traction control can compensate for SOME degree of rider error, but certainly not all of it.
ABS will work correctly when the bike is straight up and down. Hammer both front and rear brakes at will. The system will take care of modulating front/rear brake bias but only at the point of the tire trying to lock up. There is not room for cornering traction at this point (see earlier post that explained the concept of "traction circle" or "traction points").
Traction control will work when the bike is picking up acceleration out of a corner. That is what sport bike traction control does. If the rear wheel tries to accelerate quicker than the front, it cuts engine power. For a situation as described in the original post - managing what happens if the rider sees an obstacle mid-corner and has to take evasive action - this system does NOTHING for you.
ABS application due to heavy braking mid-corner at high lean angle would be on very questionable ground. The results will not be worse than doing the same thing on a non-ABS bike ... but they might not be better, either. Still, if you come around a corner to see a truck all the way across the road in your lane, better to take your chances by braking than a
for sure situation of hitting that truck as a result of
not braking. The concept of "traction circle" still applies - so if at all possible, straighten up a little while simultaneously and smoothly applying brake, aiming for the outside of the corner (and hopefully outside the obstruction) ... just like you would do with a non-ABS bike.
Twice this summer, I have had front-end slides on a street ride because of crossing a sand patch. ABS or traction control will do NOTHING in this situation.
