Big end size was increased from 1.48" to 1.68". High compression pistons and a higher lift camshaft, the 356 "sports" profile, were also fitted. These engine modifications raised the power output to 40 bhp (30 kW) and a top speed of 109 mph (175 km/h). 924:
Engine modifications included a 356 race camshaft and an Amal TT carburettor. Power output was 40 bhp (30 kW). The TT carburettor required a kink to be put in the frame's seat post for clearance. The frame also had welded on lugs for rearset footrests. A 2.5 gallon Gold Star tank was fitted

In 1951, BSA Chief designer, Bert Hopwood, went on a fact-finding tour to America and talked to dealers and riders. The feedback he got from the tour was that a more powerful motorcycle would sell well in America. The swinging arm frame and alloy head Road Rocket were planning stages but some way off

An alloy head was introduced with the Road Rocket in 1955. The RR also featured a thicker cylinder base flange (1/2" instead of 3/8") and these cylinders became known as "thick flange". The big end was increased in diameter from 1.46" to 1.68". Crankshafts and conrods with the bigger bid ends became

The Super Rocket was an improved sports model that replaced the Road Rocket in 1958. It retained the Amal TT carburettor and 356 sports cam of the Road Rocket. Compression ratio was raised to 8.5:1 and a new alloy cylinder head fitted. The cylinder head had a cast in inlet manifold and larger ports

The BSA Golden Flash, commonly referred to as the Gold Flash, was the first of the series to be launched in 1950. Painted in a new gold colour, 80% of production was destined for the United States. This resulted in long delivery times for British customers, who were offered the model only in black.

Launched in October 1949, Hopwood's A10 Golden Flash drew heavily from the A7 design by Page and Bert Perkins. The A10 was increased to 650 cc (40 cu in) by using a 70mm bore and 84mm stroke. It had a revised alloy rocker box and cast-iron cylinder head, plus an integral manifold for

Launched as the top of BSA's range in 1954 the BSA Road Rocket was the first A10 engine with an alloy cylinder head. Unlike the Golden Flash, the inlet manifold was separate to the cylinder head enabling twin carburettors to be fitted if required. Standard fitment was an Amal TT carburettor. New
