Vincent HRD

HRD designs were well ahead of their time, setting new standards that the rest of the motorcycle industry would emulate over the next decade. In 1925, an HRD set an average speed record of 66.13 mph at the Isle Of Man TT, placing HRD into the history books.

Phil Vincent & HRD

Another visionary named Philip Conrad Vincent (1908—1979), nicknamed "PCV," began building reconstructed HRD's, in the mid 1920s, renaming his new creations as "the Vincent." Early Vincents used a 499cc single cylinder engine, or the HRD's JAP 1000cc v-twin engine. Vincent even obtained a patent for his innovative cantilevered rear-suspension design in 1928.

In 1928, after studying engineering at King's College in Cambridge, Phil Vincent decided to purchase the financially strapped HRD Company. HRD was now in the hands of Ernie Humphries of the "OK-Supreme" bicycle company, who had acquired HRD after it went into voluntary liquidation. Vincent purchased HRD for a mere £500.

The newly reborn "Vincent" company was renamed "Vincent HRD Company, Ltd. in Stevenage Hertfordshire, England. Between 1928 and 1934, over twenty models were produced by Vincent HRD, four of which used the same 499cc single cylinder engine that appeared in the early Vincents. The new "Vincent HRD" company logo had the word "Vincent" in small letters above the larger initials "HRD."

Phil Irving & Vincent HRD

An Australian engineer named Phil Irving joined the company in 1931, becoming its chief engineer. Irving's first design project was the OHV 500 cc single-cylinder "Comet" and "Meteor" engines. Credit is also given to Irving for the "accidental" design of Vincent's famous V-twin engine, which was first introduced in 1936.

Irving went on to write several books, including the "Motorcycle Technicalities," and eventually received the title of "OBE," or the Most Excellent Order of the British Empire.

Vincent Black Shadow, Black Lightning & Rapide

HRD introduced the now-legendary "Black Shadow" and "Black Lightning" motorcycles in 1948. By late 1948, HRD's reputation as a formidable machine was set by Rollie Free, who rode a Black Lightning, euphemistically named the "John Edgar Lightning" for its ts sponsor John Edgar, to a record-breaking top speed of 150.313 mph at the at Bonneville salt flats.

Further adding to the legendary status and mystique of the Black Lightning, Free broke the land-speed record dressed only in a bathing suite and bathing cap, while stretched out flat on the rear fender.

Vincent Nomenclature

To further add to the confusion over the HRD, Vincent, Vincent HRD, Vincent nomenclature, the letters "HRD" were removed from the company logo in 1949, due to a perceived possibility of confusion with the Harley Davidson brand.

'Series D' - Vincent Black Knight, Black Prince, and Victor

By 1954 Vincent sales were declining, so Vincent introduced three new models that became known as the "Series D" line. The "Black Knight" was an upgraded Rapide, the Black Prince a full-fairing and upgraded Shadow, and the Vincent Victor was an upgraded Comet. The Series D lineup was introduced as touring bikes, but sales continued to decline.

Another possibly fatal mistake was the introduction of the "Firefly" (aka "Vincent Power Cycle"), a 45 cc gasoline-powered bicycle which undoubtedly irritated many loyal Vincent fans.

Vincent abruptly ceased production in 1955, after Phil Vincent announced that the company could no longer maintain solvency. The announcement was made at a Vincent Owners' Club dinner.
