As well as the sports Comet, Vincent produced a TT racing model, the Comet Special (a TT model with lights) and the standard Vincent Meteor which shared many of the same cycle parts.

The 499 cc single-cylinder, high-camshaft OHV, air-cooled Vincent engine had a light alloy barrel and cylinder head with a cast-iron liner, and a 'backbone' type combined frame and oil tank.

The engine acting as a stressed member of the frame, and most other components in common with the post-war twin-cylinder models.

At the time and to this day some members of the motorcycling fraternity quipped that it was really only 'half of' the desirable Rapide twin-cylinder model, although in fact the specification had more in common with the higher performance Black Shadow twin-cylinder model, sharing compression ratio (7.3:1) and the larger carburettor.

All Comet models had Vincent's "Girdraulic" forks and sprung cantilever rear suspension with hydraulic damping at a time when most manufacturers continued to produce rigid frames.
