Hurriedly prepared for its debut at the 1958 Earls Court Show (it was too late for inclusion in the 1959 catalog) the 'Bonnie' arrived at a time when young motorcycle enthusiasts wanted style as well as substance and had the money to pay for it. Finished in striking two-tone Tangerine/Pearl Grey with matching mudguards and black cycle parts, the bike was a real looker and the name 'Bonneville', chosen in honor of Johnny Allen's record-breaking achievements with his Triumph-powered streamliner at the eponymous Utah salt flats, was an inspired piece of marketing.

Triumph entered the 1960s with its larger twin-cylinder machines 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 this innovation duly appeared on the 650s in 1963. The cafe racer's favorite since its launch in 1959, the Bonneville continue in this new form as Triumph's top-of-the-range sports model. An alloy cylinder head equipped with twin Amal Monobloc carburetors helped the 'Bonnie' motor produce 46bhp at 6,500rpm, and the model was reckoned good for a top speed approaching 120mph.

Dating from the first year of 'unit' Bonneville production, this collectible example has been fully restored to '100 point' standard and is said to run very well, having covered only some 20 or so miles since completion.
