Abstract: A hydraulic motorcycle braking system is disclosed. In the hydraulic motorcycle braking system a pump suction valve, which is situated in a braking circuit that does not contain an isolating valve or a change-over valve, has a higher opening pressure than a pump suction valve which is situated in a braking circuit provided with an isolating valve and a change-over valve. Accordingly, pressure oscillations initiated during the start-up of the pump cannot have a retroactive effect or only have a slight retroactive effect on the actuated brake master cylinder.
