Abstract: A throttle control for a motorcycle comprises an electromagnet mounted adjacent to a throttle tube on a handle bar of the motorcycle. The throttle tube includes a radial flange on one end that is configured to define at least one slot. An armature plate is positioned between the electromagnet and the radial flange and is configured to define at least one tab that registers with the slot in the radial flange of the throttle tube. The armature plate is moveable between a first position in contact with the electromagnet and a second position spaced from the electromagnet while the tab remains within the slot. When the electromagnet is energized, the armature plate frictionally contacts the electromagnet and fixes the radial position of the throttle tube.

Abstract: A motorcycle is described which has a frame and a rear wheel attached to a driven pulley. A drive pulley is rotatably mounted to a rigid bracket attached to the frame such that a relative orientation between the drive pulley and the driven pulley is maintained substantially constant. A drive belt is coupled to the drive pulley and the driven pulley such that a rotation of the drive pulley imparts a rotation of the driven pulley. A transmission output gear is attached to an output of a transmission, and a drive coupler is provided as an interface between the transmission output gear and the drive pulley.

Abstract: A motorcycle handlebar assembly is described as having a main handlebar tube and first and second grip assemblies respectively coupled at opposite end regions of the tube. The grip assemblies each comprise a sealed hollow chamber with a volume of lead balls located in the sealed hollow chambers to provide vibration damping. A method of reducing vibration conducted to hands of a rider of a motorcycle is described to provide sealed chambers located at a grip location of a motorcycle handlebar and partially filling the sealed chamber with loose material.
