[1] Vincent-HRD began motorcycle production in 1928 and were well established after World War II when they launched the 1,000 cc (61 cu in) Black Lightning.
This was a production version of the Black Lightning which held the motorcycle land-speed record, with a similar engine specification.
[1][3] The 998 cc (60.9 cu in) air-cooled OHV pushrod V-twin specifications were always based on standard parts but upgraded with higher-performance racing equipment.
[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.
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.
