I was in low power mode with three traction control and was coming out of a turn, the back tire lost traction and was spinning. I almost did a complete 180 and was then upended over the bike. There wasn't any gravel, it hadn't rained, there weren't any obstacles in the road and there was no reason the back tire should have lost traction. Especially with the technology of the ZX6R with three levels of traction control.
