SUNBEAM S7 500

Designed by Erling Poppe - believed as a result of letters to a motorcycle magazine - it came on to the market in 1946 - straight after the war - a completely NEW concept in motorcycle design.  Produced by a division of BSA motorcycles.  487cc parallel twin OHC four stroke - 24bhp/6,000rpm - 94mph. One of the great and innovative British motorcycles of the last century.
