Anyone having trouble with their rear brakes on the new 821. Mine are hard as a rock but will not stop. Been to first service in Scotsdale Ducati and they said all is well. I can tell you all is not well. I have had 10-11 Ducs from 907, monsters, St2,916,multistradas and they all had good rear brakes. I really just use them in parking lots and coming to a slow stop. You get real scared when you push down and nothing happens. It has ABS and you can get front and rear to modulate but the rear suck in a normal stop.
