The Triumph Trident and BSA Rocket 3was a technically advanced, high-performance roadster (or standard) motorcycle made by Triumph Engineeringand BSA (both companies part of the Birmingham Small Arms Company) from 1968 to 1975, and sold under both the Triumph and BSA marques.[1] Alongside the Honda CB750, and later the two-strokeKawasaki triples, it brought a new level of sophistication to street motorcycles, marking the beginning of the superbike era.[3][4][5] The Honda CB750 overshadowed the Trident to be remembered as the 'first superbike', in spite of the Triumph Trident actually debuting before the Honda by a few weeks.
It had a 58 bhp (43 kW), 740-cubic-centimetre (45 cu in) air-cooled OHV unit construction straight-three engine, with four gears and a conventional chassis and suspension.[2] The engine had less vibration than the existing 360° twins. The Rocket 3/Trident was part of Triumph's plan to extend the model range beyond their 650 cc parallel twins. It was the last major motorcycle developed by Triumph at Meriden, West Midlands, created to meet the demands of the US market. Although BSA experienced serious financial difficulties, 27,480 Rocket 3/Tridents were produced during its seven-year history. Doug Hele continued to develop the engine, and in 1971 joined frame expert Rob North to produce the Formula 750 racing machines. At the 1971 Daytona 200 the British three-cylinder bikes took the top three places; Dick Mann won on a BSA Rocket 3, followed by Gene Romero on a Triumph Trident and Don Emde third on another BSA Rocket 3.[19]John Cooper rode a BSA Rocket 3 to an upset victory over 500 cc world champion Giacomo Agostini in the 1971 Race of the Year at Mallory Park.[20] Cooper finished three-fifths of a second ahead of Agostini's MV Agusta.[21]
The best-known bike was a production-class Trident prepared by a team led by Les Williams called Slippery Sam, a roadster prepared for production-class road racing to controlled specifications using selected adaptations only, available from the factory as part-numbered inventory. Williams' team won consecutive 750 cc production races at the Isle of Man TT for the five years between 1971 and 1975, and in the new F750 event for race-specification machines, Triumph and BSA machines with Rob North frames placed first and second.[22] Bert Hopwoodrecommended a production version of the racing triple, producing 84 bhp (63 kW) at 8,250 rpm, but his suggestion was not adopted. Further racing development was done in Duarte, California under racing manager Dan Macias.
Tom Mellor set four world speed records at the Bonneville Salt Flats in September 2008 with a 1969 Triumph Trident T150.
