Development
ABC had always had a close association with the Sopwith aircraft company and in 1919 they jointly exhibited the Sopwith 390 cc horizontally-opposed twin-cylinder overhead valve (OHV) machine at the annual Motor Cycle show. It aroused a lot of interest with innovative front and rear leaf springs and "expanding" brakes, wet sump lubrication, and a four-speed gearbox. It was also one of the first motorcycles with a duplex cradle frame. One thing it did not have, however, was any form of starting mechanism; the rider had to "paddle" or bump start to get the engine going. The ABC 400 was made under licence by the Sopwith Aviation & Engineering Co in Kingston-upon-Thames and 2,200 were produced. Later models had improved valve gear, speedometers, and electric lighting. Sidecar outfits were also produced as optional extras.
In 1920 a new company, ABC Motors (1920) Ltd was formed to make aircraft engines, light cars, and motorcycles, all with a flat-twin engine designed by Bradshaw.

Famous quotes containing the word development:
“John B. Watson, the most influential child-rearing expert [of the 1920s], warned that doting mothers could retard the development of children,... Demonstrations of affection were therefore limited. “If you must, kiss them once on the forehead when they say goodnight. Shake hands with them in the morning.””
—Sylvia Ann Hewitt (20th century)
“On fields all drenched with blood he made his record in war, abstained from lawless violence when left on the plantation, and received his freedom in peace with moderation. But he holds in this Republic the position of an alien race among a people impatient of a rival. And in the eyes of some it seems that no valor redeems him, no social advancement nor individual development wipes off the ban which clings to him.”
—Frances Ellen Watkins Harper (1825–1911)
“The Cairo conference ... is about a complicated web of education and employment, consumption and poverty, development and health care. It is also about whether governments will follow where women have so clearly led them, toward safe, simple and reliable choices in family planning. While Cairo crackles with conflict, in the homes of the world the orthodoxies have been duly heard, and roundly ignored.”
—Anna Quindlen (b. 1952)
