ABSTRACT:
A power unit for an axle having two or more driven wheels that permits the use of a conventional motorcycle power unit having an internal combustion engine and a change speed transmission having only forward gear ratios. An auxiliary transmission is coupled to the motorcycle power unit change speed transmission and itself includes two forward speeds and a reverse speed so that the vehicle may be driven in a forward or reverse direction. An interlocking arrangement is provided so that the auxiliary transmission cannot be shifted into reverse unless the change speed transmission is in either neutral or its lowest gear. In addition, the arrangement is such that a centrally positioned drive shaft may be employed.
