c.1951 Vincent 499cc Grey Flash Replica
Registration no. TYJ 486
Frame no. RC/1/6429
Engine no. F5AB/2A/5513
Development work by factory tester George Brown, himself an accomplished racer, resulted in the Vincent Grey Flash: a tuned version of the Series C Comet single with a power output of 35bhp and a top speed in racing trim of 115mph. The 'Flash retained the overall look of the Comet roadster, with Vincent's distinctive Girdraulic front fork and cantilever rear suspension, but featured an Amal TT carburettor, Elektron magnesium-alloy brake plates, and an eye-catching pale grey colour scheme. Success eluded the works Grey Flashes in the 1950 and 1951 Isle of Man TT races, but the model chalked up some notable victories on mainland short circuits in the hands of factory apprentice John Surtees. Catalogued only for the 1949 and 1950 seasons, during which time a mere 31 were completed, the Grey Flash is one of the rarest and most desirable of post-war Vincents. This replica Grey Flash features racing-type finned front brake drums with air scoops, matching speedometer and rev counter, alloy wheel rims, single-sided rear hub, Norton/AMC gearbox and matching crankcase halves. Little used since completion, the machine is described as beautifully prepared, running well and sounding very nice.
