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 tyre and an absence of lighting further distinguished the TT, which came with lowered overall gearing reflecting its intended role as primarily a dirt bike.

This TT Bonneville was subject to a 'last nut and bolt' no-expense-spared restoration to 'as new' condition circa 2000, since when it has seen very little use. The previous owner stored the machine in a heated warehouse following its acquisition in 2005, covering only a couple of hundred miles up to 2019 when ownership passed to the current vendor. Since then the Bonnie has been ridden for only some 20 miles. The machine last ran in August 2022. Accompanying documentation consists of a VMCC dating communication, a V5C Registration Certificate, and a full list of what was done during the restoration (perusal recommended).
