1954 BSA 500cc 'B33' Special
Registration no. not registered
Frame no. CB31-392
Engine no. X B34 280

This BSA B33 Special is a mixture of parts from various models. Taken from a 500cc competition model, the crankcases date from 1947 and would have been topped by an iron cylinder head and barrel originally. (The additional number 'GS 53172' on the timing side is someone's addition and should be ignored.) The frame dates from 1954 and would have started life in either a B31 or B33. The engine's alloy top end is circa 1953-1955, as used on either the BB34 Gold Star or the B34 Competition Model (assuming it is 500cc). The headlamp nacelle is B31/33 circa 1954-1957 and the front wheel is B31/33 circa 1956-1957. Mudguards are after-market ones of no particular type, while the fuel tank is a swinging-arm Gold Star type. The carburettor is a post-1966 Amal Concentric.

Little is known of this machine's history before it was rescued from a hedge by the vendor's husband. The chassis was restored by his friends in 2019-2020 but the engine and transmission were not (the engine has good compression). There are no registration documents or further paperwork with this Lot and it should be noted that the registration number 'DEN 142' does not correspond to this motorcycle and therefore will not come with it.
