Essentially a 'Tiger-and-a-half', the Triumph and BSA 750cc Triples were launched in the UK in 1969. Differences between the Triumph Trident and BSA Rocket III were more than just cosmetic: the two models used different frames and in BSA guise the motor's cylinder block was slightly inclined. BSA-Triumph had learned a lot about engine development from racing the 500 twins, and the Triples were the most powerful machines in their class. Dynamometer tested by the American publication Motorcycle Buyer's Guide in 1970, the Rocket III produced a maximum of 55.4bhp at the rear wheel, slightly down on its Triumph Trident sibling's 58.8 horsepower but 1.5bhp better than Honda's four-cylinder CB750. Meanwhile, back in the UK, Bike magazine wound their road-test Rocket III up to a top speed of 128mph. Only the Trident survived the BSA-Triumph Group's collapse in 1972, continuing as the T150V (with five-speed gearbox) and later the heavily revised T160 (using the BSA-type engine). The number of important production race victories achieved (notably by the works Triumph known as 'Slippery Sam') is eloquent testimony to how effective a high-speed road-burner a well-fettled Triple can be. Today the models enjoy an enthusiastic following worldwide and are supported by numerous recognised specialists and a first rate owners' club – the TR3OC – whose annual Beezumph Rally at Cadwell Park is highly recommended. This Rocket III was purchased by the current vendor in October 2002 and since then has been kept in a private museum. The machine has covered only 18,665 miles from new and is presented in commensurately excellent original condition. Recently serviced, it is offered with Swansea V5C document and fresh MoT.
