ABSTRACT:
A motor vehicle transmission system, for use on a motorcycle, for example, includes a sensor for detecting a direction in which a shift pedal is operated for an upshift or a downshift, a torque direction sensor for detecting a direction in which the torque is transmitted between an engine and a drive wheel, and an engine output power control assembly responsive to output signals from the sensors for temporarily increasing or reducing the output power of the engine, so that a transmission mechanism can be shifted without disengagement of a clutch.
