Graced by one of the most evocative model designations in the history of motorcycling, the Triumph Bonneville owes its existence to record-breaking successes achieved on the eponymous Utah salt flats in 1958, when a Tiger 110 set a new 650cc production machine record of over 147mph. A new alloy cylinder head with inlet ports splayed wide to accommodate twin carburetors had become available as a tuning aid early in 1958 and it was, chiefly, this innovation that enabled the specially prepared T110 to so far eclipse the performance of the standard version. Of course, the names 'Triumph' and 'Bonneville' were already inextricably linked, Texan Johnny Allen having set a new World Motorcycle Speed Record of 214mph on Utah's famous salt flats in September 1956 in his Thunderbird-powered streamliner.
Triumph lost no time in capitalizing on its technical breakthrough, announcing a new model equipped with the splayed 'head and twin Amal carburetors in September 1958: the Bonneville. Testing a T120 'Bonnie' in June 1961, Motor Cycling found that Triumph's range-topping sportster possessed abundant vitality. 'With exceptional top-end performance goes extraordinary vigor and tractability at low and medium speeds - a combination which makes it perhaps the fastest point-to-point roadster produced in Britain today.' As far as the dedicated Triumph enthusiast was concerned, there was no 'perhaps' about it.
This 'matching-numbers' '66 Bonnie is offered fresh from a painstaking total restoration undertaken between August 2005 and September 2006 by Steve Steinbrink, who purchased the machine from its original owner. Work carried out included a total engine/transmission rebuild; cadmium plating of fastenings; powder coating the frame; and repainting the cycle parts, while new parts fitted include the Amal carburetors, control cables, instruments and rubber components. Finished in Aubergine/Alaskan White, the machine has covered a mere 50 'shakedown' miles since completion and is reported to be 'ready to ride'. Offered with Certificate of Title.
