Then the prototypes of the ABC first appeared in 1919 they featured one of the most advanced specifications of any motorcycle up to that date.
The ABC was fitted with front and rear suspension, front and rear drum brakes, a four-speed gearbox, a mmli-plate clutch unit, and a tubular cradle frame.
The 398cc flat twin engine was mounted transversely in the frame and had overhead valves. In many ways the ABC was a forerunner of the BM\V transverse twin that appeared in Germany in 1923 though because it was fitted with rear suspension the British machine had chain drive. The rigid-framed BMW used a shaft.
The light weight of the ABC promised good performance despite the small-capacity engine. Front and rear springing promised a comfortable ride. On both counts the ABC delivered. The ABC illustrated is a 1921 model. Originally made in England, the bikes were made under licence in France by aircraft engine-makers Gnome & Rhone between 1920 and 1924

ABC motorcycles was a British motorcycle manufacturer established in 1914 by Ronald Charteris in London. Several British motorcycle firms started up with the name "ABC", including Sopwith. The All British Engine Company Ltd. of London was founded in 1912 and later changed to ABC Motors Ltd. With chief engineer Granville Bradshaw, Charteris built a range of engines throughout the First World War. From 1913 ABC produced motorcycle engines.
In 1918, ABC made a motorcycle with a 500 cc flat-twin engine mounted with its cylinders across the frame, several years before BMW adapted the design. Bradshaw challenged BMW's use of his patented design in 1926. In 1919 ABC also produced the Scootamota – an early motor scooter. The company stopped producing motorcycles after 1923 because of competition from cheaper manufacturers ,Vintage Motorcycle,vintage motorcycles,vintage motorcycle helmets,vintage motorcycle jacket,vintage motorcycle parts,vintage motorcycle tires,vintage motorcycle goggles,vintage motorcycle racing,vintage motorcycle t shirts,vintage motorcycle boots,vintage motorcycle values
