106 BSA 348cc B31 (1949) OVW 957 by Robert Knight Via Flickr: BSA 347cc B31 (1945-51) Engine 347cc OHV Registration Number OVW 957 (Essex) BSA ALBUM www.flickr.com/photos/45676495@N05/sets/72157623759878630... BSA's rugged, workaday B31 was manufactured from 1945 to the end of 1959, its overhead-valve engine providing the basis for the renowned Gold Star sports roadster. At the time of its introduction, the B31 was BSA's sole all-new model, joining the lightweight 'C' and heavyweight 'M' ranges carried over from pre-war days. Produced initially with rigid frame and telescopic front fork, the B31 gained (optional) plunger rear suspension in 1949 and an all-new swinging-arm frame in '54. A good all-round performer by the standards of its time, the B31 could cruise comfortably all day at 60mph while returning 75-plus miles per gallon, virtues that endeared it to private owners and police forces alike.
