1951 Vincent Grey Flash Replica - Bonhams at Stafford

Based on a Series C Comet 500 single, a striking Grey Flash replica is for sale as part of the Bonhams Motorcycle auction at Staffordshire County Showground on 24 April 2011.

Originally capable of 115mph the racing trim Grey Flash was a formidable and rare racer- only 31 were ever produced. With an output of 35bhp at 6200rpm the works machines never won a TT race but did take several victories on the continent and famously at gave Geoff Duke's Norton a scare at Thruxton with John Surtees at the helm.

This particular Grey Flash Replica is complete with rear cantilever suspension, Girdraulic front forks and would make an excellent period race machine. It carries a pre-sale estimate of £8,000- £12,000.
