With the apocryphal tale of Vincent-HRD Series A twins being conceived as a result of two single-cylinder drawings being overlapped, it could be said that the post-war single cylinder engine was brought about by the use of a rubber – removing the rear cylinder of the existing twin-pot design.
In other respects, the layout was almost identical, with the same ‘frameless’ cycle parts being employed for both types. On the singles the rear cylinder was replaced with a cast alloy beam, and the gearbox employed was the familiar Burman item, the older versions of which had been popular before the war. Announced in late 1948, a few Series B Meteors were produced before it was joined soon after by the Comet in Series C form with hydraulic forks, as opposed to the Brampton girders on the Meteor.
