Abstract: An air suspension device includes a housing enclosing a compressor chamber that communicates with an air source and at least one piston chamber, optionally through internal air ports. A compressor is disposed in the compressor chamber. When the compressor is driven by a power source, such as a motor, the compressor draws air from the air source and drives the air into the piston chamber. A piston disposed in the piston chamber is cushioned by the pressurized air.

Abstract: In a first aspect of the present invention, the system of the present invention includes motor vehicle handlebars in which the cables, wires, and lines are disposed within the bars for protection and aesthetics. The handle of the handlebars includes channels for cables, wires, lines, and the like running from the controls at the handles to the devices controlled. To accommodate the wires, the system further includes small switches in which the contacts maintain the switch in the closed position when contact is made. A second aspect of the present invention includes an oil reservoir for a hydraulic brake or clutch system. The reservoir includes a reservoir piston. The piston includes a stem, optionally removable, for bleeding air from the reservoir. The reservoir fluidly communicates with a fill hole and a master cylinder.

Abstract: Disclosed is an improved automatically actuated motorcycle lift stand. The stand comprises upper and lower stand units on each side of the motorcycle. This configuration enables independent raising of the motorcycle when resting on either side, as well as providing a normal parking function. Also disclosed is an improved linear actuator comprising a plurality of concentric telescoping members. Two embodiments of single groove ball return elements are disclosed.

Abstract: A hydraulically, pneumatically, electrically, or engine operated motorcycle center stand assembly having a ground-contacting lower stand unit rotatable about an axis on an upper stand unit. Parking is accomplished by rotation of said lower stand into said ground-contacting position, followed by downward pivoting of said upper stand unit, thereby raising said rear end of said motorcycle. The stand is raised by reversing the sequence. Ground contacting area, stand width, and stability are increased while simultaneously retaining maximum road clearance.
