So i purchased my 2013 S1KRR on Valentines day 2017. It had 1900 miles on the odometer. It now has 21k. A couple months ago I was riding to work and noticed that when I let off the gas the bike would slow down quickly like the engine braking had been turned way up. When I stopped at the light after exiting the freeway I felt a tremendous amount of heat on my right leg. When I looked down my rear rotor was glowing white. I was able to ride through the intersection and pull over. I sat there for a good 30 minutes until it cooled enough to release the rear brake. I rode the last couple blocks to work and by the time I got there it was already heating up again. I took the rear wheel off and the pads and rotor were toast. So I cleaned and lubed everything and put it back together temporarily and I ziptied the rear brake lever so I could not use it. I made it home from work without incident. I replaced the rear rotor and caliper and bled the rear brake. Rode it for about a month and and everything is fine until... I was on my way from work and I almost lost it on the freeway because of a car cutting me off. I had to hit my brakes hard enough to get the bike wiggling at appx 75 mph. That was enough of a scare to get me to turn on the abs again. Rode with it off since the brake overheat incident. So I made it appx 20 miles down the freeway and the increased engine braking happens again. This time I immediately pulled over and sure enough the rear rotor was starting to get red hot. So i remembered that I had switched on the abs before the ride and figured that it had to be related. I turned off the abs and rode the 20 miles home without incident and the rear brake worked like normal. So I purchased a Gs911 and plugged her in...no fault codes, all abs functions ok. What could it be?
