Dude, let me point out right here and now, that the stock tires on every single one of the r6 bikes built since 2006 are FAR better than the tires on every single other slower, heavier, worse in every attribute besides comfort, non race replica bikes ever built in the history of motorbikes. They are better than the racebike tires were just a few years ago when traction control meant right wrist coordination and giving it a little english. At roadway speeds, its pretty much 99.999999% rider input that makes or breaks your ride, assuming there isnt an additional inciting factor causing your bikes unlikely low-sided demise. Maybe there was gravel, sand, water, oil, etc, and maybe there wasnt. I bet you'll pay attention the next few times you make that uturn, though.
I will say though, traction is a really picky bitch. Ive seen traction made and broken in so many ways on two wheels, from rocketship level dirt bike and sand drag launches to 4 minute burnouts to you name it. There really is a pretty small edge on the envelope of the gray area. Its small enough to where unless you've had a lot of experience with it, you wont know what it feels like, let alone what it feels like when right before it piledrives you face first into the tarmac. On some level, at some point, you have to go with the less is more, pin it to win it, grip it and rip it philosophy. What happens next....well, my old man would say, "Sometimes you eat the bear, but then, sometimes he eats you."
but yeah, Im with the dude, above, you fcuked up somehow. Some of us have ridden in snow, rain, and on frozen roads at decent speeds, and didnt crash, let alone on dry pavement.
