Under the sole ownership of Ernie Humphries and family, the OK Supreme motorcycle flourished from 1926 through 1939 although under Humphries' former partnership with Charles Dawes, the company history had roots, simply as OK, back to 1882 with bicycles and experimented with motorized cycles as early as 1899. When Humphries assumed all motorcycle production in 1926, the name became OK Supreme. JAP engines in various configurations were mostly utilized from that time hence until the very end when Matchless engines were brought in, and included side valve singles, OHV singles and V-twin engines until the cessation of motorcycle production in 1939 to assist in manufacturing for the war effort.

OK Supreme's only Isle of Man TT victory occurred in 1928 when they had four finishers in the top six places in the lightweight class with Frank Longman taking the win. This singular win undoubtedly boosted sales dramatically for the handsome single cylinder motorcycles manufactured in Birmingham, England.

This OK Supreme was originally sold to a client in Austria where it not only survived the World War II, but also remained unmolested through the years. Professor Fritz Ehn purchased the OK Supreme in 1968 and continued to ride the motorcycle on a regular basis on vintage runs and other times displayed it in the RAF Museum. The motorcycle is in original condition in sports configuration, featuring a 350cc OHV JAP engine with twin exhaust ports and TT exhaust pipes. Not your usual motorcycle, this a unique opportunity to purchase a fully road worthy late vintage motorcycle in original condition and enjoy the un-muffled bark of an English single cylinder motorcycle. Offered on a Bil of Sale.
