ABSTRACT:
A five speed motorcycle transmission with coaxial input and output drives. The transmission includes a driveshaft and a countershaft rotatably mounted in a gear housing for supporting transmission system components and gear arrangements. Input torque is applied in a conventional manner to one end of the driveshaft and transmitted through the transmission components in the selected gear ratio to an output sprocket which is freely rotatably mounted on the drive shaft. Torque shifting means in the form of axially displaceable drive dogs splined to the driveshaft and countershaft can be shifted axially by conventional shifter means for selectively transmitting torque from the driveshaft through various gear arrangements to the output sprocket. The gear arrangements include a high speed overdrive gear arrangement, a high speed direct drive gear arrangement, and three low speed drive gear arrangements.
