  • Publication number: 20040182669
    Abstract: A shifter handle for a motorcycle or ATV which has an integral clutch release lever, operable by the fingers of the same hand used for shifting the gears. Being mounted in either the jockey position, adjacent to the seat, or the tank shift position which is mounted vertically from the shifter pedal shaft, the clutch controls are removed from the handlebars making said clutch release lever integral to the handle used for shifting the gears. Trends in the custom cruiser industry are to remove the visible controls from the handlebar area for aesthetic purposes. There are important applications such as the area of modification for the handicapped. Spinal cord injured persons with little or no use of the legs, or amputees where a foot shift device is impossible to use need no longer be prohibited from enjoying riding this type machine. The hand shift devices of the past are no longer precarious or dangerous with both operations in the same hand.
