Abstract: A hydraulic motorcycle clutch system includes a master cylinder, and a slave cylinder. The slave cylinder operates as a clutch release mechanism to disengage a clutch in response to the master cylinder. The clutch release provides a pulling force on the clutch to relieve a compression force applied to clutch disks of the clutch. One embodiment of the slave cylinder includes dual concentric seals and a stepped piston. The stepped piston design provides for reliable control of the travel distance of the clutch release. The clutch release is also self adjusting over a wide variation in clutch disk thicknesses.
