Just FYI -
I have two Roadsters (2011 & 2012). While hooning the twisties, the rear brake pedals on BOTH motors would eventually lock solid preventing any use of the rear brakes. Very scary and very dangerous! I finally had to pull the rear ABS fuses which cured the problem in both motors. At least I can now trail-brake the twisties without fear of the sudden suprise of losing my rear brakes entering a twisty.
Rocket Roadsters have POS rear ABS in my humble opinion!!!
I had bled the hell outta both looking for consistent pedal operation.
Even paid for the $100 brake bleed tool.
All in all twas a HUGE waste of time, money and brake fluid.
