I have a 2012 wing, while crossing on of the nastiest roads in South Florida, In the rain, I had the rear brake, start to grab the disc. Scared the Crap out of me, thought I was going down. got it to the shop, and the techs, put it up on the centerstand, and spon the rear wheel to find it locked up a few times. they stated, It hasn't happened to a 12, that they knew of. anyone else every have this issue?
