1947 BSA 499cc B33
Frame no. B31 9559
Engine no. XB33 815
A development of the 350cc B31, the 500cc B33 was manufactured from 1947 to 1960. The engine closely followed B31 lines but with larger (85mm) bore and heavier flywheels. Cycle parts were identical apart from a larger-section rear tyre. Produced initially with rigid frame and telescopic forks, the B33 was available from 1949 with optional plunger rear suspension, switching to a swinging-arm frame, along with the rest of the BSA range, in 1954. A good, solid, all-round performer by the standards of its day, the B33 could top 80mph, cruise comfortably all day at 70mph and return in excess of 70mpg. With virtues such as these it is no wonder that versatile classics such as the B33 are fondly remembered by older enthusiasts and keenly sought after today. This tidy 'rigid and teles' example dates from 1947. The machine is described by the vendor as nice and original, benefiting from some light restoration while retaining many original parts and features. We are further advised that it will require re-commissioning before returning to the road. There are no documents with this Lot.
