ABSTRACT:
An axially short, variable-ratio gear transmission suitable particularly for motorcycles has a first or input shaft, a second or output shaft, and a countershaft. First and second rotatable gears on the input shaft permanently mesh with respective first and second rotatable gears on the output and counter shafts. The first and second gears on the countershaft are permanently connected for joint rotation, a first coupling permits one of the two gears on the first shaft to be coupled to the first shaft, and a second coupling similarly may couple one of the gears on the second shaft to the latter.
