1955 Vincent Grey Flash Replica 500 cc


The Grey Flash is widely regarded as the holy grail of the Vincent Marque, with only 37 Grey Flash’s being manufactured from 1949 to 1951.

The stripped down  race version weighing only 150 KG and the road model with lights etc.,  slightly heaver. Building the Grey Flash racer was a bold move on the company’s part as Vincent was nearly bankrupt. Even bolder was fielding a team of 3 bikes for the 1950 Senior TT race. Although this effort gained a lowly 12th place, it showed that Vincent was still in business. Over the years many copies have emerged and have caused no end of controversy and quite understandably so as with only 37 bikes being made the Grey Flash truly is the holy grail of the Vincent Marque.


This Grey Flash replica in beautiful condition both cosmetically and mechanically; it was featured at length in ‘The Classic Motorcycle’ June 2008 issue where it was given the most glowing report imaginable. Very well known bike with the Vincent owners club and much admired by all who have had the privilege to look at this masterpiece of engineering.

The spec includes: – Alloy Tank which is believed to be an ex Works item, correct Close ratio Albion Gearbox, Twin finned Electron Front Brakes, Lightening Mk2 Camshaft, polished engine internals, the unique girdraulic fork has been lightened by machining a large grove down the back of the station plus masses of drill boles in the none loan bearing areas all exactly as the original and all for extra  weight saving.


This Grey flash is bar far the best replica we have ever come across and is definitely not just a Comet in a ‘Fancy Grey Dress’ Virtually undistinguishable from the original, the obvious clue being the frame and engine numbers; If one of the 37 ever came to market it would sell from anything between one and two million pounds. This very well known machine   comes with a very large history file and great province.


The chance to purchase of this magnificent machine is a once in a lifetime opportunity. I will be sorry to see this bike go, as it is such an inspirational piece of work that rarely comes our way. It must be said that out of all the bikes I have had in my unique collection this one is right up there at the top. The Grey Flash Rep comes with very large history files, boxes in fact !  are available on request to seriously interested buyers. The bike has seen very limited use since 2008.
