1966 Triumph 646cc 'Bonneville' (see text)
Registration no. JTR 127D
Frame no. 6T DU42239
Engine no. T120 DU31613

Triumph's 650cc models had entered the 1960s recognisably 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 this innovation duly appeared on the 650s in 1963. The café racer's favourite since its launch in 1959, the Bonneville continue in this new form as Triumph's top-of-the-range sports model.

The machine offered here conforms broadly to 1966 Bonneville specification but has a frame that started life in a Thunderbird, the twin-leading-shoe front brake fitted from 1968 to 1970, and flashing indicators (not adopted until 1971). Acquired by the current vendor in December 2011, the 'Bonnie' has been kept on display in a restaurant since then and will require re-commissioning before returning to the road. Sold strictly as viewed, it comes with the 2011 sales contract and a V5C registration document.
