magneto, sprung forks and excellent finish. Within six months from their launching, BSA"s were selling well. The machines were easily distinguishable among rival makes by their
yellow and green painted tanks. A TT rear-hub, two-speed model was soon added. Until well into the 1930s, various models were added, adapted or discontinued.
1915 There was a choice between the 85x88 3.5hp model and the 85x98 4.25hp model. This latter machine was offered as being especially suitable for sidecar work. It also had the three-speed BSA gearbox with foot controlled clutch that was introduced in 1914 and a double barrel
BSA carburettor. Both models could be had in chain-cum-belt version or in all chain drive with encased chains, which made the machine three pounds and five shillings more

Harold Briggs who designed new sporting machines for them, including their
popular 493cc ohv Sloper of 1928.
1928 They made their first and only two-stroke, a 175cc unit construction
bike, for only one season.

Page, who was formerly of Ariel

and simplified models that were no longer economical to produce. His work
remained in production until the 1960s. They took over Sunbeam

the wars. In 1939, the company owned 67 factories across the UK. During

tyres and much more chrome-plating. They announced a new competition model,

1971 Company reorganisation centred production at the Triumph
site and together BSA and Triumph
launched ranges which included many new models using common parts, such
as forks and wheels. By this time the company was in deep financial trouble
as, although an industrial giant, the company proved unable to compete
well against the Japanese. The 1971 lineup saw major makeovers, including
oil-in-frame 650cc twins. BSA was bought by Norton
(owned by Manganese Bronze) and absorbed into the Norton-Villiers-Triumph
group in 1971, which managed to design an uncomfortably high A65 Lightning
at Umberslade Hall before BSA collapsed.

demolition of the factory at Small Heath.

assembled from imported components. Many of these machines were built for
third-world countries and the services.

Aquilini family. BSA Co. was sold and a US company (Bill Colquhuon's
BSA Co.) used the name for Rotax-engined
military bikes and Yamaha-based
Bushman machines for developing nations. In 1991, Andover Norton and BSA
Co. merged to create BSA Group, which was taken over in 1994
to form BSA Regal. They announced a new Gold SR using a Yamaha SR400
engine in a Gold Star styled chassis.
