As the 1960s dawned, Triumphs larger twins remained recognisably similar to the first Speed Twin of 1938. 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. The café racers favourite since its launch, thanks to lusty acceleration and a top speed approaching 120mph, the Bonneville continued in this new form as Triumphs 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 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. For the next couple of seasons the Bonnie continued essentially unchanged, before the disastrous launch of the oil-in-frame models in 1970 precipitated the collapse of the entire BSA-Triumph Group. This highly original and unrestored 68 Bonnie was purchased by the vendor from its first owner in 1973, at which time it had covered circa 3,000 miles. Always kept garaged, the machine has covered a mere 9,629 miles to date and is only offered for sale because its owner is emigrating. The machine benefits from a professional engine rebuild carried out in 2005 at a cost of circa £1,500 and is offered with related invoices, current road fund licence/MoT and Swansea V5 registration document. A top-box, owners manuals, and a quantity of assorted spares are included in the sale.
