Development
Vincent Motorcycles began motorcycle production in 1928 and were well established after World War II when they launched the 1,000 cc (61 cu in) Black Lightning. This was a production version of the Black Lightning which held the world land speed record, with a similar engine specification.
Available to order, a standard Black Lightning was supplied in racing trim with magnesium alloy components, special racing tyres on alloy rims, rear-set foot controls, a solo seat and aluminium fenders. This reduced the Lightning's weight to 380 lb (170 kg). The 998 cc (60.9 cu in) air-cooled OHV pushrod V-twin specifications were always based on standard parts but upgraded with higher performance racing equipment. The Black Lightning had higher strength connecting rods, larger inlet ports, polished rocker gear, steel idler gears, racing carburettors, a manual-advance magneto and was available with compression ratios between 6.8:1 and 12.5:1. This resulted in 70 bhp (52 kW) and a top speed of 150 mph (240 km/h). Only 31 Black Lightnings were ever built before production ended in 1952 because of Vincent's financial problems.

Famous quotes containing the word development:
“Theories of child development and guidelines for parents are not cast in stone. They are constantly changing and adapting to new information and new pressures. There is no “right” way, just as there are no magic incantations that will always painlessly resolve a child’s problems.”
—Lawrence Kutner (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)
“Women, because of their colonial relationship to men, have to fight for their own independence. This fight for our own independence will lead to the growth and development of the revolutionary movement in this country. Only the independent woman can be truly effective in the larger revolutionary struggle.”
—Women’s Liberation Workshop, Students for a Democratic Society, Radical political/social activist organization. “Liberation of Women,” in New Left Notes (July 10, 1967)
