Maybe instead of using an extra brake line to control the center piston on the front caliper when applying rear brake, they use an abs block similar to the harley's that somehow proportions a percentage of the front brake pressure when applying rear brake.
Linked would also mean applying front brakes should affect rear brake too, right? If so, how does it do that? Same concept? I wouldn't think "linked" brakes only apply when using the rear brake.
