1949 BSA 348cc B31
Registration no. WVS 972
Frame no. ZB31S 2708
Engine no. YB31 3565
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. This plunger-suspended B31 dates from 1949 and has been fitted with an engine of slightly earlier (1948) manufacture. Restored by its first owner in 1993, it has had only two owners since and covered fewer than 1,000 miles while in the care of the vendor, who acquired it in 1996. Benefiting from a recently reconditioned magdyno, the machine is presented in good condition throughout and offered with all MoTs for the period 1996 to date; sundry restoration invoices; current MoT/road fund licence; and Swansea V5C registration document. We understand that a BSA Owners Club dating certificate has been applied for.
