  • Patent number: 4633727
    Abstract: An auxiliary foot actuated gearshift for a motorcycle is disclosed wherein an independent pivot shaft is established at the near midpoint location of the auxiliary gearshift lever in such a manner so that downward pressure on the auxiliary gearshift at the pedal (outboard) end causes an upward pressure on the opposite (inboard) end which rests against the under side of the existing gearshift lever. This action pushes the existing gearshift up and allows the operator to shift from the low range of gears to the high range of gears by applying downward pressure on the auxiliary gearshift. Since the original existing gearshift has not been altered by the installation of the auxiliary gearshift, shifting from the high range of gears to the low range of gears is accomplished by downward pressure on the original existing gearshift. All shifting therefore can be accomplished by downward pressure on either the existing or the auxiliary gearshift.
