The Vincent Black Lightning was a Vincent-HRDmotorcycle first built in September 1948 at the Vincent works in Great North Road, Stevenage, Hertfordshire, UK, and produced from 1948 to 1952. The bike was a purpose-built factory modified Black Shadow that was then named and produced as the Black Lightning. At the time the Black Lightning was the fastest production motorcycle in the world.[1]
Vincent-HRD began motorcycle production in 1928 and were well established after World War II when they launched the 1,000cc (61cuin) Black Lightning. This was a production version of the Black Lightning which held the motorcycle land-speed record, with a similar engine specification.[2]
Available to order, a standard Black Lightning was supplied in racing trim with magnesium alloy components, special racing tyres on alloy rims, rear-set foot controls, a solo seat and aluminium mudguards. This reduced the Lightning's weight to 380lb (170kg).[1][3] The 998cc (60.9cuin)air-cooledOHVpushrodV-twin specifications were always based on standard parts but upgraded with higher-performance racing equipment. The Black Lightning had higher-strength connecting rods, larger inlet ports, polished rocker gear, steel idler gears, racing carburettors, and a manual-advance magneto, and was available with compression ratios between 6.8:1 and 12.5:1.[4] This resulted in 70bhp (52kW) and a top speed of 150mph (240km/h). Only 31 Black Lightnings were ever built before production ended in 1952 because of Vincent's financial problems.[1]
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 148.6mph (239.1km/h). 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 23.9seconds, passing the 150mph (240km/h) barrier and on the return run he reached a record average speed of 150.313mph (241.905km/h).[5][6][7][3][8] 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.[8][1] In 1950, Rollie Free returned to the Bonneville Salt Flats and broke his own record, averaging speeds of 156.58mph (251.99km/h) on the Vincent despite a high-speed crash during those speed trials.[5]
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.[9]
Richard Thompson song
Richard Thompson wrote the song "1952 Vincent Black Lightning" and recorded it for his 1991 album Rumor and Sigh.[10] Thompson later said, "When I was a kid, that was always the exotic bike ... the one that made you go 'ooh, wow'".[11] 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."[12]

Vincent Motorcycles was a British manufacturer of motorcycles from 1928 to 1955. The business was established by Philip Vincent who bought an existing manufacturing name HRD, initially renaming it as Vincent HRD, producing his own motorcycles as HRD did previously with engines purchased as complete assemblies from other companies. From 1934, two new engines were developed as single cylinder in 500 cc and v-twin 1,000 cc capacities. Production grew from 1936, with the most-famous models being developed from the original designs after the War period in the late 1940s.
The Vincent Black Shadow is a British motorcycle designed and built at the Vincent works in Great North Road, Stevenage, Hertfordshire UK. Motorcycles produced by Vincent H·R·D at their factory in Stevenage, Hertfordshire, England were renowned for their design innovation, engineering excellence and high performance. Already advertising their existing 110 mph Rapide machine as "The world's fastest production motorcycle", in February 1948 the distinctive Vincent Black Shadow was announced with a top speed of 125 mph. Built in three different Series over the course of its life, the line continued until 1955, after which the company stopped all motorcycle production.
Herbert James "Burt" Munro was a motorcycle racer from New Zealand, famous for setting an under-1,000 cc world record, at Bonneville, on the 26th of August 1967. This record still stands; Munro was 68 and was riding a 47-year-old machine when he set his last record.
HRD Motors Ltd was a British motorcycle manufacturer in the 1920s. It was founded by Howard Raymond Davies. He had worked in motorcycling, and had raced with some success in the mid-twenties, but often not finishing due to unreliability. This inspired him to build a reliable performance motorcycle, using the advertising slogan "Built by a rider". Others also aimed at a similar market, like George Brough of Brough Superior motorcycles.
Roland Robert Free was an American motorcycle and automobile racer best known for breaking the American motorcycle land speed record in 1948 on the Bonneville Salt Flats, Utah. A picture of Free, prone and wearing a bathing suit, has been described as the most famous picture in motorcycling.
The motorcycle land-speed record is the fastest speed achieved by a motorcycle on land achieved by Martynas Kišonas. It is standardized as the speed over a course of fixed length, averaged over two runs in opposite directions. AMA National Land Speed Records requires 2 passes the same calendar day in opposite directions over a timed mile/kilo while FIM Land Speed World Records require two passes in opposite directions to be over a timed mile/kilo completed within 2 hours. These are special or modified motorcycles, distinct from the fastest production motorcycles. The first official Fédération Internationale de Motocyclisme (FIM) record was set in 1920, when Gene Walker rode an Indian on Daytona Beach at 104.12 mph (167.56 km/h). Since late 2010, the Ack Attack team has held the motorcycle land speed record at 376.36 mph (605.69 km/h).
Electric motorcycles and scooters are plug-in electric vehicles with two or three wheels. Power is supplied by a rechargeable battery that drives one or more electric motors. Electric scooters are distinguished from motorcycles by having a step-through frame, instead of being straddled. Electric bicycles are similar vehicles, distinguished by retaining the ability to be propelled by the rider pedaling in addition to battery propulsion.
The Vincent Black Prince was a British motorcycle made between 1954 and 1955 by Vincent Motorcycles. A year before the factory closed in 1955, Vincent produced the enclosed range of Vincent Black Knight and Black Prince. Philip Vincent described it as a "two-wheeled Bentley", and the enclosed Vincents attracted a lot of attention at the November 1954 Earls Court show. Quality problems with early production of the glass-fibre mouldings necessitated a replacement supplier causing delays. The last Black Prince left the Vincent production line on Friday, 16 December 1955.
The BSA Lightning Clubman was a 650cc British motorcycle made by BSA at their factory in Birmingham between 1964 and 1965. Finished in gold and black the Lightning Clubman is now a highly sought after classic motorcycle. Due to the very limited production numbers replicas are created by enthusiasts from the BSA Lightning.
The Triumph Bonneville T120 is a motorcycle originally made by Triumph Engineering from 1959 to 1975. It was the first model of the Bonneville series, which was continued by Triumph Motorcycles Ltd. The T120 was discontinued in favour of the larger 750 cc T140 in the early 1970s.
The Triumph Tiger 110 is a British sports motorcycle that Triumph first made at their Coventry factory between 1953 and 1961. The T110 was developed from the Triumph Thunderbird and first appeared in 1954.
The TOP 1 Ack Attack is a specially constructed land-speed record streamliner motorcycle that, as of March 2013, has held the record for world's fastest motorcycle since recording a two-way average speed of 605.697 km/h (376.363 mph) on September 25, 2010, in the Cook Motorsports Top Speed Shootout at Bonneville Speedway, Utah. The Ack Attack's fastest one-way speed was officially recorded at 634.217 km/h (394.084 mph). This was the third time in four years the Ack Attack had broken the motorcycle land-speed record.
BUB Seven Streamliner is an American-built streamliner motorcycle that held the motorcycle land-speed record from 2006 to 2008 and again from 2009 to 2010. BUB Seven and two other streamliners traded the title of "world's fastest motorcycle" during official speed runs at Bonneville Speedway in the summer of 2006. The other two competitors were Ack Attack and the EZ-Hook streamliner. In 2017, Valerie Thompson rode BUB Seven for more record attempts at Bonneville.
The Lambky Liner is a motorcycle land-speed record streamliner designed by Navy veteran and Vincent motorcycle restorer Max Lambky from Kansas, United States. It reached a top recorded speed of 250 mph (400 km/h) at the 2007 International Motorcycle Speed Trials, and an estimated 275 mph (443 km/h) in second gear before a supercharger spindle broke and spoiled a run in 2008.
