The café racer's favorite since its launch in 1959, the Bonneville continued as Triumph's top-of-the-range sports model after the switch to unitary construction of the engine/gearbox in 1963. An alloy cylinder head equipped with twin carburetors helped the 'Bonnie' motor produce 46bhp at 6,500rpm, and the model was reckoned good for a top speed approaching 120mph. The USA had long been Triumph's most important export market, and to cater for local tastes a 'TT Special' (also known as the 'Competition Sports') Bonneville was introduced in 1964. The Triumph twin was already a formidable force in American flat-track racing, and the TT Special's stripped-down look, smaller fuel tank and short, open exhaust pipes echoed the style of the racers. By this time a maximum output of 52bhp was claimed for the Bonneville, while the TT Special engine produced 54bhp courtesy of 11.2:1 pistons (up from the T120 roadster's 9.0:1). A crankcase under-shield, tachometer-only instrumentation, larger-section front tire and an absence of lighting further distinguished the TT, which came with lowered overall gearing reflecting its intended role as primarily a dirt bike. Dating from the final year of TT production, this example, an original matching-numbers machine, has been used. It does not have 'heavy' knobby tires so may have been used for trail riding rather than further afield in the desert. It is complete and unrestored. It is ready for restoration or can be ridden as is after some mild re-commissioning. It carries a VMCC Extract from Works Records as a factory T120TT Special and was last serviced in 2018 by Arizona British Bikes who report it runs well.
