Thus the Series B Rapide of 1946 was radically innovative, eliminating the traditional tubular steel frame by incorporating the engine as part of the chassis. This, plus combining the engine and gearbox – not yet the norm – and pivoting the swingarm off the back of the gearbox allowed a shorter wheelbase for quicker steering. Ducati’s current Desmosedici MotoGP bike pivots its swingarm off the gearbox for the same reason.
The entire motorcycle was, in fact, beautifully thought out, not only to maximise performance but also to reduce maintenance and improve aesthetics, with oil pumps, plumbing and so on built-in rather than attached externally.
The Series B was good for 110mph, making it the world’s fastest production motorcycle of the time. But Vincent wanted more. Next came the 125mph big-port Black Shadow and the Black Lightning race bike, the latter made famous by Rollie Free, who rode one to the US motorcycle land speed record, wearing only swimming trunks. Black Lightnings broke speed records the world over.
At the same time the booming V-twin became the dominant force in the 1000cc Clubmans TT on the Isle of Man. This was an amateur event but that didn’t bother Vincent, who preferred building motorcycles that could be raced by privateer riders to making one-off factory specials, which bore little resemblance to production machines.
The two Phils – Vincent and Irving – also produced an upgraded Comet, the Grey Flash, for racing in the 500cc class.
One of these was bought – in bits for £70 – by London motorcycle dealer Jack Surtees, for his 16-year-old son John, the only racer to win the greatest prizes on two and four wheels, the MotoGP and Formula 1 championships. Surtees junior scored his very first victory aboard the Flash in 1950 and joined Vincent as an apprentice engineer the following year. “Working at Vincent’s was a key step in my development as a competitor who could fully understand his machinery,” recalled Surtees, who commuted between home and Stevenage riding borrowed Rapides or Black Shadows.
Three decades later Surtees was still in love with Vincents, restoring his Grey Flash and rebuilding a Black Lightning special he had first put together in the 1950s.
Sadly, the brilliance of the two Phils and the reverence in which their creations were held were not enough to keep Vincent on the road. Selling expensive motorcycles during the post-war years of austerity was never going to be easy, whatever their reputation. The last Vincent came off the Stevenage production line at Christmas 1955.
Five Vincents will be at the Goodwood Revival weekend: a Black Lightning, a Black Shadow, two Rapides and a Grey Flash, which will wear No97, the same number Surtees used on his Grey Flash at Goodwood in 1951. If you don’t see them you will hear them.
