I've been posting a lot lately, here's something else that I've been thinking about:
I bought my most recent ride in large part because of the availability of traction control. I bought it about a month after a friend of mine crashed when she had to swerve onto some wet railroad tracks to avoid a car. As she described it the engine revved, the rear wheel spun, and she went sideways and high sided.
I know that TC is typically used on motoGP bikes as a sort of artificial intelligence, allowing riders to pin the throttle on corner exits and accelerate at the most optimum pace.
I have also read a little about how TC works, by retarding the ignition timing (which is a little opaque to me) and by shutting down fuel flow to cylinders (which is a little more obvious.)
BMW offers ASC on the 1200's, and on the RR, but they don't offer it on the 800's or on the new scooters. My friends bike was a 250 incidentally.
Wondering what people think of this issue. I'm sure there will be a lot of "I've gone 30 years without it" posts. My first real bike had ABS, and that probably effects the way I brake in many situations. I grew up driving Subaru's, and am pretty used to cars that automagically don't fish tail.
