Gear

The Sportster gear box is a 4-speed constant mesh type, (contained in an extension of the crankcase), that permits the rider to vary the ratio of engine speed to the rear driving wheel speed in order to meet the varying conditions of operation.

The transmission is foot operated by the gear shifter lever on the right side of the engine which transmits the force through a gear shifter shaft, actuating a pawl carrier, pawls and gear shifter cam. The shifter cam moves shifter forks which slide a series of gear clutches on the mainshaft and countershaft into mesh with the various gears to obtain the desired gear ratios.
