Patent ID: 7204349

Claim:
A rotor system for a vehicle having at least one hydraulic actuator for being in fluid communication with, and thereby actuating, at least one hydraulically-actuated component selected from the group consisting of a brake and a clutch, the rotor system comprising: a steering head tube; a handlebar stem that extends from a fork, wherein the handlebar stem extends into the steering head tube and is mounted for rotating relative to the steering head tube; and a rotor mounted proximate the steering head tube, with the rotor including an internal piece mounted inside the handlebar stem and an external piece mounted outside the handlebar stem so that there can be substantially unrestricted relative rotation between the internal piece and the external piece, wherein the internal piece and the external piece are operatively connected so that the fluid communication between the hydraulic actuator and the hydraulically-actuated component is at least partially via the rotor, and the fluid communication between the hydraulic actuator and the hydraulically-actuated component at least partially via the rotor is maintained while there is relative rotation between the internal piece and the external piece.
