This paper presents two types of the dual mode transmission for use in a motorcycle. A motorcycle transmission typically using the discrete speed ratio transmission that works by alternating the gear drive, and the continuously variable transmission (CVT) that transmits power by using the rubber V-belt. The dual mode transmission described in this paper, utilizing a V-belt drive, a fixed ratio mechanism, and a planetary gear train, can provide two operation regimes over the full speed ratio range by means engaged clutches. One is the fixed gear ratio and differential transmission system; the other is the differential and continuously variable transmission system. The kinematics, power flow, and mechanical efficiency of each transmission system are analyzed. An example is employed to illustrate the design procedure. Furthermore, several available design concepts of the dual mode transmissions for motorcycle applications are proposed.
