1977 Triumph T140 Bonneville with 1967 TR6 engine Frame #: T140V PX01807 Engine #: TR6 DU58226 As the 1960s dawned, Triumph's larger twins remained recognizably similar to the first Speed Twin of 1938. Unitary 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. The café racer's favourite 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. By this time the frame had been sorted and 12-volt electrics standardized, but welcome improvements included shuttle-valve fork internals, independently adjustable ignition points, Amal Concentric carburettors and a long overdue twin-leading-shoe front brake. For the next couple of seasons the Bonnie continued essentially unchanged, before the launch of the 'oil-in-frame' models in 1970. The bike offered consists of a 1977 frame, stamped for November build date of that year, with all the modern amenities of disc brakes and later model suspension, and mounted in it is a 1967 TR6 650cc engine with single carb, one of the best configuration motors ever produced by Triumph. The bike runs well, starts easily and idles smoothly. Gearbox shifts well with a good clutch. All cycle parts work well and there are no leaks to speak of. The bike has a clean, clear California title. On Oct-07-12 at 12:07:48 PDT, seller added the following information: Please note the Engine is a 'C' model. The Engine number is TR6C DU58226
