The overhead cam 500cc 4F was produced from 1931 - 1932; only 927 were made. In 1932 the displacement was increased to 600cc and the OHC model continued until 1936, when they dropped the OHC design, and reverted to push rod operation. The re-designed engine was made in two displacements; 1,000 cc (4G model), and 600cc (4F). Relatively few 600cc bikes were made; approx 2,700 from 1932 - 1940.

Square Four production figures were around 16,000 in all between 1931 - 1958.
