Launched at the Olympia Motorcycle Show, London in 1926, the overhead valve Brough 680 was often over shadowed by its bigger brother the SS100, in fact George Brough himself nicknamed the ohv 680 as the ‘Miniature SS100’ however it was no less a ride and although the model gave away some 300cc to the SS100 it was formidable motorcycle, lighter and with sharper handling it was easily capable of 80 plus mph and has continued to be one of the most collectable models.
A lower list price made sales of this 680 an instant success reflected in the 547 overhead 680’s being built, second only to the JAP powered SS80. Some 127 examples are known to have survived complete, this example here has been in the Hitchcock collection since the 1950’s and is available on the open market for the first time since then.
The Brough Superior Club UK hold most of the surviving factory records but the information for this bike is not available, although the bike is known to the club and known to have been in the Hitchcock collection in the Folkstone (Kent) area since the 1950’s.
An original buff log book with the bike states the engine number as GTOI/87882/SD ( Single Cam ) although the bike has been upgraded with a twin cam engine from 1928 bearing the number GTOY/C 98246, factory records for this do survive and are with the bike, stating that it was supplied in frame number 674 in January 1928 to Jarvis and Sons, Surrey and fitted with a Binks twin float carburettor, which it retains.
In addition 618 also retains and large number of very fine original parts, including the mudguards, the correct type of gearbox, Castle front forks and what appears to be the original registration number.
There have been many Brough restoration projects that have come to the market in recent years, however this 680 has been stored well and remains in generally good solid condition with the structural integrity of the frame intact. A truly great ‘barn find’ from a prestigious collection, offered here for the first time in some 60 years.
