Vincent Black Lightning

Vincent-HRD began motorcycle production in 1928 and were well established after World War II when they launched the Black Lightning. This was a production version of the Black Lightning which held the motorcycle land-speed record, with a similar engine specification. Available to order, a standard Black Lightning was supplied in racing trim with magnesium alloy components, special racing tires on alloy rims, rear-set foot controls, a solo seat and aluminium mudguards. This reduced the Lightning's weight to . This resulted in and a top speed of . Only 31 Black Lightnings were built before production ended in 1952 because of Vincent's financial problems. ==US record and picture==

speed record attempt at Bonneville Salt Flats in 1948 in 2009 On 13 September 1948, Rollie Free achieved the US national motorcycle speed record at Bonneville Salt Flats in Utah riding the first Vincent Black Lightning. During test runs Free reached average speeds of . To reduce drag, Free stripped to his swimming shorts for the final run, which he made lying flat with his legs stretched out and his head low, guiding the Vincent by following a black stripe painted on the salt bed. The stunt worked as Free covered the mile in 23.9 seconds, passing and on the return run he reached a record average speed of . This led to one of the most famous photographs in motorcycle history, known as the "bathing suit bike". The American Motorcyclist Association certified Free's record. Innovative features of the bike included the first-ever Vincent rear shock absorber, the first Mk II racing cams and horizontally mounted racing carburettors. In 1950, Rollie Free returned to the Bonneville Salt Flats and broke his own record, averaging speeds of on the Vincent despite a high-speed crash during those speed trials. ==Auction record==

In February 2018, during an auction held by Bonhams at Las Vegas, a Black Lightning, stated to be one of only 19 surviving, set a world record for the highest-price paid at auction for a motorcycle of $US929,000 ($1.16 million Australian). The machine was used to set a national speed record in Australia during 1953, and was purchased by an undisclosed Australian. ==Richard Thompson song==

Richard Thompson wrote the song "1952 Vincent Black Lightning" and recorded it for his 1991 album Rumor and Sigh. Thompson later said, "When I was a kid, that was always the exotic bike ... the one that made you go 'ooh, wow'". The song's outlaw hero James, who has "robbed many a man to get my Vincent machine," comments on the bike's mystique in his dying speech: Says James: "In my opinion, there's nothing in this world, beats a '52 Vincent, and a red-headed girl. Now Nortons, and Indians, and Greeveses won't do; they don't have a soul like a Vincent '52." ==See also==
