Abstract: A cover for a master cylinder assembly and a portion of a brake pedal of a motorcycle includes first and second cover members. The first cover member covers an outer end of the brake pedal hub, and covers the master cylinder assembly. The brake pedal is movable with respect to the first cover member. The second cover member is fixed to an inner end of the brake hub for rotation with the brake pedal hub. The second cover member is at least partially disposed within the first cover member. A slot is defined between the first and second cover members through which a lever portion of the brake pedal extends. The slot allows full range of motion for the brake pedal.

Abstract: The invention is intended for incorporation into an enclosure confining fluid about an electromagnet of the type having a core, at least one coil disposed about the core and a current source coupled to the coil to establish a magnetic field. According to the invention, at least a portion of the peripheral wall of the enclosure surrounding the core axis resides in non-parallel relationship with the axis of the core. As a result, a part of the peripheral wall portion is in closer proximity to the wire coil than the remainder of the wall portion. As a result, the heat readily conducts through the wall portion and is dissipated efficiently. The surface exposed to the atmosphere with the above construction has a greater area than would a planar wall parallel to the core axis so that heat dissipation is enhanced.
