1950 VINCENT COMET (Series C) 500cc


  •  Increasingly desirable Vincent 500 single
  •  Older restoration still in great condition
  •  Verified matching numbers ‘C’ model bike
  •  Very low miles since refurbishment
  •  Rides well


Introduced in 1948, the desirable model C Comet is considered the ultimate Vincent 500 single and had quite a bit in common with the renowned higher performance Black Shadow twin-cylinder machine.

Back in the day, the Comet was noted for it’s superb roadholding, steering and brakes, and was arguably the best 500cc single ever produced by a British motorcycle company.

This fine example has been cosmetically restored and mechanically rebuilt to a high standard over a number of years following it’s return to blighty.
The Purposeful stance of ‘The Vincent’ is set off by the shining black paintwork and original specification fittings. The originality, condition and low mileage make this bike a great show-piece and rideable choice.

This fantastic matching numbers Comet doesn’t come with any early history but is likely (but not confirmed), to have been imported from the U.S. in 2002 and then restored by the first U.K. owner. 

Mechanical parts, purchased from The VOC Spares Company Ltd, Cheshire, suggest a mechanical overhaul was undertaken along with the replacement of some ancillary and cosmetic components from 2002-2006. 

The second owner also appears to have undertaken a degree of mechanical work with a further thirteen invoices from The VOC in evidence from 2007-2011 (see photos).
