The pre-war Series A Rapide offered a level of performance unrivalled by the vast majority of its rivals, however the vee-twin engine configuration resulted in a long wheelbase endowing the machine with slow, albeit stable, handling.

The Stevenage based company promised a revised model in their wartime advertising that would address this issue together with the cluttered appearance of the engine due to the external oil lines that gave it the "plumber's nightmare" nickname. The result was promised to be fast, capable of cruising at 100mph, with exemplary handling and braking, a high degree of rider comfort and easy maintenance.

The solutions adopted in order to achieve their aims were radical. The full cradle frame was discarded, with the engine becoming an integral part of the machine. A fabricated oil tank incorporated the headstock mounting to the engine. At the rear of the engine brackets provided pick up points for the cantilever suspension system. Brampton girder forks were employed at the front, although their limitations were recognised and their subsequent replacement by Girdraulic units defined the Series C variants. A gearbox built in unit with the engine further aided the reduction in wheelbase in comparison to the Series A machines. The lubrication system for the engine was refined improving the appearance of the unit and aids to maintenance were incorporated into the design such as wheels that could be removed without the aid of tools. Twin drum brakes were employed on both wheels endowing it with exceptional braking distances.

That they largely achieved their aims is now a matter of historical record, although it was not until the Series C models arrived with the Girdraulic front forks that the two engineers were entirely satisfied. The example offered was built by a long standing Vincent Owners Club member using a Comet chassis with a Rapide engine fitted. First registered in 1978 it was built with a view to use and incorporated a number of sensible improvements making it better able to deal with modern traffic conditions. A 12 volt electrical system incorporating indicators and a (currently disconnected) electric start were fitted. Uprated brakes, more modern carburettors, an oil filter and centre stand all contribute to its ease of use which has seen it complete two Moto Giro de Italia's whilst in the present owner's hands. Regularly serviced by a Vincent specialist prior to being Mot'd each year, it is described as being in very good condition in respect of the engine, transmission, electrical system and cycle parts with fair paint and brightwork. It is accompanied by a number of bills relating to the annual service and a current V5C together with an old example.
