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 Girdraulic forks, as opposed to the Brampton girders on the Meteor. The Comet was a little more expensive, being equipped with the new forks, a higher compression ratio, front propstands, and a modified, slightly longer, rear frame section.
