It had been Philip Vincent belief that provision of ample weather protection combined with enclosure of engine and gearbox, would make the Vincent Series-D the ultimate “gentleman’s motorcycle”, though delayed delivery of the glassfibre panels – plus continuing demand for traditionally-styled models – resulted in over half the production leaving the Stevenage factory in un-enclosed form. The enclosed Rapide and Black Shadow were known as Black Knight and Black Prince respectively. Other Series D innovations included a new frame and rear suspension, a user-friendly center stand, plus many improvements to the peerless v-twin engine. When production ceased in December 1955, around 460 Series D v-twin had been build, some 200 of which were enclosed model. The Black Knight styling was so ahead of his time that 10 bikes has been used as a futuristic Police vehicle in the 1955 movie “1984” inspired by the famous George Orwell’s novel “Nineteen Eighty-Four”.
