Motorcycle transmission shifting device

The invention provides a motorcycle transmission shifting device and belongs to the technical field of motorcycles. The problem of how to reduce arrangement space so that the structure compactness ofthe shifting device can be improved is solved. The shifting device comprises a shifting shaft arranged on a shell, and a shifting drum; the shifting shaft is provided with a shifting arm and can drivethe shifting arm to swing; a fixed shaft is fixed on the shell; the fixed shaft is rotationally connected with a transmission connecting lever and a locking arm for locking the shifting drum; and thetransmission connecting lever is in transmission connection with the shifting connecting lever and can drive the shifting drum to rotate through a transmission mechanism. According to the shifting device, through the design of the transmission connecting lever and the coaxial arrangement of the transmission connecting lever and the locking arm, the structural arrangement of the shifting device ismore reasonable, the arrang
