@Hotfoot-
Thanks for the comment about "it is possible to perceive feedback from the bike that tells you when you are approaching the limit; there are warnings from the bike and tires." I too have been looking for this feedback and often wondered if it's a matter of getting to the point of actually stressing the equipment (of course assuming good technique).
I could experience some of those limits when I was mini-moto racing (it's hard to spin a rear-tire with 9HP- ha!), but didn't even come close on the big bikes. For example: on my 600, I tried in earnest to break traction on the gas at apex but that tire would stick and shoot me out of the corner and I'd get more courage to get on the gas harder the next lap in the same corner...nada! I never tempted fate on my 1000 (excluding the high-side I had in the wet), but did try and get better launches down the front straight coming out of the last turn at NJMP. By this time, though I was older (implying wiser) and tempered my wrist a bit.
I look forward to riding again at these levels and higher.
Does the bike and tires "talk" at all levels of riding or is it only in the upper band of the performance envelope?
