1954 VINCENT RAPIDE-NEARING THE END
Vincent built its reputation on it’s robust 499cc Comet single. Prior to the war, they figured out that if they doubled it, they could create a 998cc V-twin and the series A Vincent Rapide was born. Few were built prior to World War 2, which curtailed all civilian production to focus on producing war materials. But, they used this time to completely redesign their new V-twin and by war’s end, they were ready to release the Series B Rapide. It now had a 50-degree V-angle instead of the Series A’s 47.5-degree V. The top end oil plumbing was now contained within the engine itself, rather than externally as before. And now the engine, gearbox and primary case were enclosed in one common casting, an early example of unit construction. This allowed the engine to be used as a stressed unit, eliminating the need for front down tubes and an engine cradle. The new Series B Rapide used Vincent’s tried-and-true ‘cantilever’ rear suspension, taken from the Comet and Meteor. Traditional Girder-style front forks were used with a single coil-over damper. A trademark of Vincent V-twins is their dual front brakes, one on each side. Rather than redesign a new larger unit, they just used the one they already had…twice! In 1948, the Rapide was eclipsed by Vincent’s new premier bike, the Black Shadow. The Black Shadow had a slight power bump over the Rapide and so was faster, earning it the title “The World’s Fastest Production Motorcycle”. And it was. The easiest way to tell a Rapide from a Black Shadow is that Rapide engines are polished alloy (silver), and Black Shadow engines are painted gloss black. 1955 would the last year of Vincent Rapide production, as the company closed down for good.
1954 VINCENT RAPIDE SERIES C
The Series C was introduced in late 1950 and ran through early 1954. The main difference between the Series B and C was that the Series B had a Brampton girder front end and the Series C had the new Girdraulic telescopic front forks from Girling. Huge improvement in ride and handling.
