1953 Vincent HRD Black Shadow
Post WW2, British manufacturer HRD/ Vincent set out to manufacture the fastest production motorcycle available. In 1948, using a performance modified HRD Rapide with the 1000cc Vincent V-twin engine as the basis for this new model, it became known as the Black Shadow featuring a black enamel covered engine and cylinders. Higher compression pistons were used along with larger twin AMAL carburetors and three stage valve springs allowing the motorcycle to achieve speeds approaching 125mph in early testing, far and away faster than the parallel twins of the day.
Not only was Vincent’s engine superior to other post war bikes, but the patented triagonal swinging arm suspension with a single rear shock absorber graced all HRD/Vincent models while other manufacturers made do with hard tail frames and mildly sprung seats. To further enhance handling, suspension components attached directly to the engine eliminating many elements of a tubular frame. This in part was due of the scarcity of tubular steel immediately after the war. With the engine as a stressed member of the frame the Black Shadow had a shorter wheelbase than other V twin motorcycles thus improving cornering and handling. Front suspension featured a sprung girder style fork assembly shared by other Vincent models.
Perhaps the single most iconic feature of the Black Shadow was the 5” Speedometer placed prominently above the handlebar reading up to 150 mph. The location was said to allow the rider quick access to the bike’s speed while being able to concentrate on the road ahead. With expensive semi-custom parts utilized throughout the Black Shadow, the bikes were available only to the wealthiest of enthusiasts. By the mid 50’s, the Black Shadow cost and pre-war styling began to erode popularity and by 1958 Vincent had fallen into receivership.
