BSA Classic Motorcycles

Britain's largest and most successful motorcycle manufacturer was BSA (Birmingham Small Arms Company).

Their factory at Small Heath was a familiar Birmingham landmark for more than a hundred years and produced a wide range of motorcycles from the humble Bantam to the formidable Rocket with its three-cylinder ohv engine mounted transversely. BSA motorcycle history.

The end of hostilities on the 11th November 1918 resulted in a profound change taking place in society, demobilised soldiers were returning to civilian life having been introduced to mechanical transport by the military. The motorcycle manufacturers, returning to civilian production were keen to exploit the potential new market, which by 1924 saw the number of motorcycles on the road pass the 500,000. Many of these were lightweights providing basic transport, however, the sidecar was becoming increasingly popular as a means of transport for the more affluent when attached to a single or one of the large capacity vee-twins.

Introduced during 1921, the 770cc BSA twin was available with the option of a number of factory built sidecars, although it could be ordered as solo and fitted with a "chair" produced by one of the many specialist manufacturers.

Throughout the 1930's BSA concentrated on producing competitively priced, reliable, good quality motorcycles supported by an extensive dealer network which enabled the compny to survive the economic turmoil that closed many of their rivals. At the head of the range was the G series sidvalve twins intended primarily for sidecar work. Displacing 985cc these handsome beasts were offered with the option of factory fitted sidecars and came fully equipped with electric lighting systems, footboards and carriers.

1939-1942 BSA Airborne Folding Paratroopers Bike

BSA Airborne bicycles have become quite sought-after in recent years, and this one is in good operational order. If you fancy a genuine World War 2 vehicle, this model must surely represent the cheapest option.

The BSA Airborne Bicycle was developed at a time when the only British Troop-carrying glider was the Hotspur. Like the Welbike, transport for the Para's was needed that was small and could easily be transported. As a result, BSA, who made the M20 Motorbike, developed a bicycle that could be folded in half so a paratrooper could jump out of an aircraft with it. When folded out, it was used as a conventional bicycle. They were used in all the major landing such as D-day and Arnhem. More info.

BSA announced their post war range, consisting of four models, in August 1945, headed by the sporting B31. The new model was derived utilised the M series crankcases endowing it with a "bombproof" bottom end fitted with an over head valve top end. Early models relied on telescopic forks and saddle springs to provide rider comfort and it was not until 1949 when the machine offered was built that the option of a plunger sprung frame became available.

The C12 used the same engine as the earlier C11G but in a more modern chassis. It had reasonable suspension, usable brakes and comfortable seat which meant it was more useful than the earlier models. Minor engine modifications meant it was also far more reliable.

For while it can reach nearly 100mph, an A7 is capable of returning 60mpg even when ridden hard.

As well as making the legendary Gold Star 4-stroke single, which was successful both as a cafe racer for the road as well as a popular steed for the Clubmans TT on the IOM, their Bantam 2-stroke singles of 125cc and 175cc capacity proved to be a great hit with commuters.

BSA A10 Rocket Goldstar BSA A10 Rocket Goldstar Legend has it that the Rocket Gold Star's origins can be found in a special built by Eddie Dow for a customer during 1959. That machine utilised a Goldie rolling chassis fitted with an A10 Rocket engine, a combination that worked so well Mr Dow passed the details to Small Heath. The machine that eventually emerged during 1962 met with universal praise at the time and is regarded today as one of the most desirable classic British motorcycles.
The Gold Star rolling chassis offered fine handling and braking whilst the A10 engine fitted with a light alloy head, sports profile camshaft and 9.0:1 compression ratio produced a healthy 46bhp without the cantankerous low speed behaviour that characterised a GP equipped Gold Star single. Fitted with a close ratio gearbox as standard and offered with a range of options including alloy racing fuel tanks, a racing "silencer" that was claimed to offer another 4bhp and alloy wheel rims it quickly established itself as a favourite of the cafÚ' racer crowd and production racer.

BSA announced the new A65 and A50 unit twins for the 1962 model season. Both models were considerably lighter than their predecessors thanks to the employment of unit construction for the engine and gearbox, although the mechanical architecture was little changed from the previous pre unit twins. The styling reflected the "clean" lines of the engine and gearbox resulting in a fresh uncluttered look for the machines. Development would see the unit twins continue in production until the collapse of BSA in the early seventies with higher tuned variants appearing, however, it is arguable that the first series of machines were and are among the best of the breed.

1966 BSA Cheney Goldstar BSA Cheney Goldstar

Eric Cheney had a successful career as a rider from 1946 until 1961 before applying his talents to the manufacture of beautifully prepared scramblers utilising his own frames. Many of these housed heavyweight singles produced by Matchless and BSA although from the mid to late '60s unit Beeza singles and Triumph twins became more significant.

During 1966 Eric Cheney produced a batch of oil in frame Gold Star powered scramblers, one of which was purchased by the vendor of this example. Another was supplied to Keith Hickman for use in that years European Championship during which he secured a victory at the Mogens Rasmussen round.

Although the vendor of this machine sold his original example during 1967/68 he harboured a desire to acquire another which was fulfilled in 2006 with the purchase of the one offered. The machine had originally been built during 1966 and supplied to Richard Brough who kept the bike for the subsequent forty years. During that time it was maintained by Jack Smith of Birmingham.

BSA produced several variations of their unit constuction OHV 250 single, introduced in 1958, and the restyled C25 was reasonably successful with its chrome guards and squared off alloy barrel. It represented a move forward for BSA, though some would say a little too late when compared to the competition.

The D175's engine employed new crankcases and cylinder, a revised head with a central spark plug and a stiffer crankshaft.
