Triumph Trident the last major motorcycle by Triumph Engineering at Meriden, and was a air-cooled unit construction pushrod triple four gears and conventional and suspension. It was badge-engineered to be sold both the Triumph and  BSA The Rocket3 / Trident was part of plan to extend the model beyond their 650 cc twins.

Created to meet the of the USA market, the smooth 750 cc had less vibration than the 360°  twins. BSA fell serious financial troubles, but the seven-year production run 27,480 / Trident models were

Although designed in the mid-1960s . the BSA / Triumph Trident engine had its in a 1938 parallel twin, the 500 cc   Speed Twin of 1937 by Edward Turner. The 1938 Tiger 100 a sports version of the Speed and in essence the Trident three-cylinder engine is a “ Tiger 100 and a ” (although the triple has a longer than the “ squarer ” Tiger 100 Following Triumph tradition, OHV  Trident engine has separate camshafts for and exhaust valves.

The three-cylinder design was started in by Bert Hopwood and Doug Hele. test engineers developed the of the chassis by affixing lead onto a standard 650 Bonneville. The prototype, P1 . was running by 1965, and it that Triumph might a machine in production by 1967.

the decision to produce a BSA version sloping cylinders and to employ Ogle give the early Tridents / 3s their ‘ square tank ‘ not only robbed the prototype of its looks and added 40 lb ( ) of weight, but also delayed by 18 months. During 1966, a P2 prototype was with a more production-based engine, with changed bore and … dimensions and cooling. Ultimately, Hele 90 bhp  ( 67 kW ) from a engine, leading to speculation if development had sped up in 1964, a ( 230 km/h ) British superbike have been a reality in

Although most British used a wet multiplate clutch, triple had a dry single-plate clutch in a housing between the primary and the gearbox. Mounted on the end of the gearbox where one might expect to the clutch there was instead a transmission shock-absorber.

All the three-cylinder engines, and the Rocket 3 were produced at BSA’s Heath site, but final assembly of the Trident model was carried out at in Coventry. The major differences the engine and frame: The BSA had an  A65-style cradle frame (with mounted at a slant), while the had a Bonneville-style single down frame with vertical Other differences were

Triumphs sold better in the US BSA’s  Daytona racing successes of the 70s . However sales did not meet and for the 1971 model year a gear was added, creating the BSA A75RV  and  Triumph . BSA were having financial and only some 205 five-speed 3s were built before of the BSA variant ceased. Production of the Triumph T150V (with a disc brake replacing the drum) continued until For the 1975 model year the was updated to the  T160 .

The triples had a classic “ Triumph ” with a rounded tear-drop However, BSA/Triumph commissioned design company to create a “ new look ,” this redesign to an 18 month delay. The result was a fuel-tank and a less traditional look, and the BSA was given sloped and ‘ RayGun ‘ silencers.

The Rocket 3 / Trident was introduced in the of 1968 to critical acclaim, but four weeks later it was by the introduction of the Honda CB750 . to the British triple, the more CB750 had a five-speed gearbox, overhead oil-tight engine, electric and disc brake. The Honda the Triumph in the target USA market, and in in a bid to revive sagging sales, restyled export versions the original ‘classic’ look.

in 1968, the new triples were to the American BSA-Triumph management, were disappointed. They Honda had a bike coming and felt the price of $1,800 ( ) was too high and technical (like vertically-split crankcases and OHV  valve train were far from “ edge .” However, they that the bike was fast, and the USA team decided to launch of the by using a Rocket-3 to set some at Daytona, (records which only broken in 1971 by the Z1 ).

Vincent Comet Series A

Series A Vincent-HRD singles the model which set the Stevenage on the road to immortality. The story that the engine was designed in four months, as Vincent was by the performance of ‘bought in’ engines.

on the classic scene, genial Bill Bewley restored fabulous Series A Comet in time for the 2009 Stafford show, where it was among the picking up the award for Best . Since then, it’s the Carole Nash stand at the International Motorcycle show, it was on the main Mortons stand at April 2010. However, it was a bit ( Black ) shadowed at Stafford – Bill’s equally well version of Vincent’s 125mph won top prize there, chosen as in show.

The Series A Comet be overlooked though. Arguably the ‘ A ’ was the most important motorcycle history, and tales of its conception are So the story goes, disgusted by the of ‘ special ’ proprietary  JAP  engines in his Isle of Man TT racers during the event, Phil Vincent to no longer depend on bought-in

In just four months, the designed prototype single engine was ready for display at the motorcycle show, whereupon Vincent ( PCV ) confidently predicted a top of 80mph for the cooking Meteor, for the sportier Comet and a ton for the racing TT despite the fact no engine had yet run.

However, PCV’s was proved well-placed – and there was no surprise, as the engine was the work of Australian Phil Irving. The ‘ cam ’ engine – the camshaft is set as high as in the timing chest, allowing pushrods to be used; a similar to Velocette’s M series – proved a fast and reliable unit.

The A single of course was doubled up to the first Vincent ( HRD ) V-twin . the Post-WWII singles (and were extensively redesigned. without the Series A singles, there would surely been no Rapides, no Black no Black Lightnings, no Gunga no Rollie Free record no Nero… The importance of the Series A in the Vincent pantheon should not be now, the model has become and with its historical significance and good looks, it’s surprising.
