Brough Superior 680 OHV

The Brough Superior 680 OHV, also called the Overhead 680, was a smaller and cheaper motorcycle in the range built by George Brough at his works on Haydn Road in Nottingham, England. It was powered by a J.A.P. 680 cc overhead valve V-twin engine, in contrast to the larger thousand cc machines that carried the SS80 and SS100 names. About 547 were manufactured between 1926 and 1936, which made it the second most numerous of the four models that the Wikipedia history of the marque describes as the bulk of manufacture, behind only the SS80. Like other Brough Superiors it was largely built to the buyer's order, so many variations of the basic machine exist. Production of every Brough Superior motorcycle ended in 1940 when the factory turned to war work.
