Abstract: A hydraulically operated motorcycle height adjuster which may be used with "Softail" rear suspensions, includes a remote height adjustment knob that can be manipulated from the rider's position. The height adjuster comprises a height control unit including the height adjusting knob and a height adjustment unit connected between the motorcycle frame and the swing arm of the "Softail" suspension. The height control and adjustment units are hydraulically coupled so that rotation of the knob in one direction causes extension of a strut from the height adjustment unit thereby rotating the swing arm to lower the vehicle. A compression spring inside the height adjustment unit provides spring suspension which becomes stiffer as the motorcycle is lowered. The spring raises the motorcycle from its lowered position when the height adjustment knob is turned in the other direction permitting hydraulic fluid to flow from the adjustment unit back into the height control unit.
