Lot 376: c1954 BSA 348cc B31

Sale of Collectors' Motorcycles, Bonhams & Butterfields (12 November 2005)

Based on the pre-war B29, BSA’s dependable B31 was manufactured from 1945 to 1959, its overhead-valve engine providing the basis for the renowned Gold Star. Produced initially with rigid frame and telescopic front fork, it gained (optional) plunger rear suspension in 1949 and a 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 75mpg-plus. The vendor describes this example as substantially complete.
