Development
The Dragonfly was known as the Dart while in development and was based on the Mark V Douglas and an earlier 500 cc (31 cu in) prototype. Aiming to overcome the outdated image, designers were commissioned from the Reynolds Tube Company to develop a completely new open duplex frame of welded tubing, including a swinging arm with twin Girling dampers (state of the art for the time) with leading link front suspension. The strengthened and streamlined 348 cubic centimetres (21.2 cu in) engine had a modern coil ignition, AC generator and distributor, with bolt-through cast iron cylinders and heads and pushrods made from Duralumin.

Famous quotes containing the word development:
“The American has dwindled into an Odd Fellow—one who may be known by the development of his organ of gregariousness.”
—Henry David Thoreau (1817–1862)
“They [women] can use their abilities to support each other, even as they develop more effective and appropriate ways of dealing with power.... Women do not need to diminish other women ... [they] need the power to advance their own development, but they do not “need” the power to limit the development of others.”
—Jean Baker Miller (20th century)
“Dissonance between family and school, therefore, is not only inevitable in a changing society; it also helps to make children more malleable and responsive to a changing world. By the same token, one could say that absolute homogeneity between family and school would reflect a static, authoritarian society and discourage creative, adaptive development in children.”
—Sara Lawrence Lightfoot (20th century)
