My guess is you installed the wheel spacers incorrectly.....

Doubt it as they are not inter changeable......unless i mixed up with front

EDIT.....Fcukin hell... just checked and had one of the spacers mixed with the front.. identical except back is 3mm longer ... and just did a trackday like that .....anyway cheers, just need to get new sensor now and brake pads

Glad you found it and no one was hurt in the process….. except your pride and your wallet, lol.

most track junkies use spacers that are retained on the wheel, to cut down on that happening. Might be worth it for you.

^^ I have been of the impression that the speed of both wheels is measured and compared for the traction control functions, which are installed on all models '13+. ABS is looking for a skidding condition of either wheel..... TCS is looking for fear wheel spin from overpowering available grip.

I would be very surprised if you would lose brakes altogether due to an abs fault. The liability for Kawasaki is too great. You almost certainly default to manual brakes.
