It was to be the Vincent that would usher the company into a bold new future, a "two-wheeled Bentley," in the words of Philip Vincent, who considered the design his best work. It's flowing, all-enclosing bodywork would set new standards of refinement, allowing gentlemen riders to commute to work in a crisp business suit, not leathers or nasty old waxed cotton. Ironically, what was to be a breakthrough machine for Vincent Motorcycles turned out to be a prelude to the company's last chapter. In December of 1955 a Black Prince was one of the last-ever Vincents to roll off the Stevenage assembly line before the factory was closed for good.

This particular Black Prince, purchased in September of that year from a Stockton, California dealership, is unique for several reasons. First, it is still owned by the same man who bought it new, Daniel Bienfang, a racer who shared track time with the likes of Dick Mann, Al Gunter and Joe Leonard. When he wasn't banging handlebars on northern California dirt tracks aboard a Matchless G80, Bienfang logged road miles on his beloved Black Prince, for many years his 'daily driver'. To date the bike has covered some 135,000 miles, starting in '55 when Daniel uncrated the Vincent himself and rode it home. He proudly reports that to this day he is the only person who has ever wrenched on the bike.

Among the work carried out along the way was a cosmetic restoration in 1969, that, while not exactly 'by the book' only adds to this bike's charm. The fiberglass body panels were resprayed the correct gloss black, but the result was much 'deeper' and more durable than usual at the time as Bienfang's painter friend had access to a preproduction sample of Imron paint. Next, a talented local pinstripe artist used gold-leaf to embellish the stock accent lines. Many of the bike's trim pieces were sent off to the chrome-platers. Beneath the bodywork, the bike's black-enameled engine cases were also redone, this time with some metalflake added to the paint.

About the engine, Mr. Bienfang informs us that it has never been apart, except when he installed Stellite camshafts at 110,000 miles, another unique aspect of this very special Black Prince which has been in one man's care for the past six decades. Included in the sale are numerous snapshots of the bike taken over the years.
