The BSA Golden Flash (A-10) came to life in 1949 in direct response to Triumph’s 6T, and the horsepower race was on in the British motorcycle industry. The A-10 used more advanced metallurgy in motor construction and was considered the superior motor at the time. By 1954 the Golden Flash variant had a swing arm suspension and improved transmission and clutch. In 1955 the A-10 Rocket models were offered with twin carbs while the Golden Flash kept the single Amal carb. 80% of the production went to the US market.
The 1956 BSA Golden Flash sported a 646 CC (39.4 CID) air cooled four stroke overhead valve parallel twin that produced 35 HP moved through a four speed transmission for a top speed of 105 MPH. The motor was available in a ‘High Compression’ variant that raised compression from 7.2:1 to 8.0:1 with a slight HP boost. The bike had hydraulic suspension on both ends, weighed 450 pounds and vastly improved brakes from earlier models.
