I had a '02 Honda CBR1100xx before my 04 GT. The linked brakes on the CBR are really wierd. If you pressed the rear pedal, the inner front caliper pistons were activated along with the two outer rear caliper pistons. If you pulled the front lever, the two outer pistons on the front rotors were activated and then the rotational forces on the front left rotor caliper assy moved the whole assy and activate a small master cylinder on the left fork leg which activated the inner rear caliper piston. totally over complicated. I obviously removed the whole system by intsalling a 3-2-1 brake line kit. I think they are out of the UK. Anyways, the BMW servo system is wierd too, but much better than that system IMO.
