![]() The motorcycle offered here is a finely restored example of the 1968 model and is reported to run perfectly, starting with a single kick. For the next couple of seasons the Bonnie continued essentially unchanged, before the launch of the 'oil-in-frame' models in 1970. By this time the frame had been sorted and 12-volt electrics standardised, but welcome improvements included shuttle-valve fork internals, independently adjustable ignition points, Amal Concentric carburettors and a long overdue twin-leading-shoe front brake. The café racer's favorite since its launch, thanks to lusty acceleration and a top speed approaching 120mph, the Bonneville continued in this new form as Triumph's top-of-the-range sportster, arriving at what aficionados consider its ultimate specification with the launch of the 1968 model. Unit construction of engine and gearbox was already a feature of the 350 and 500 twins though, and that innovation duly appeared on the 650s in 1963. As the 1960s dawned, Triumph's larger twins remained recognisably similar to the first Speed Twin of 1938. 1200 CC HT TWIN ENGINE: The 1200cc parallel twin retains all of its power, torque-rich performance, and trademark sound and charismatic 270 firing interval.
