Every Triumph enthusiast knows that the Bonneville owes its name to record-breaking successes on the eponymous salt flats, but how many are aware that the machine which set a new 650cc production machine record of over 147mph in 1958 was a Tiger 110 equipped with twin carburettors? A development of the Thunderbird tourer, the T110 prototype performed brilliantly in the 1953 ISDT, thus providing the production version - launched later that year - with invaluable publicity. The first Triumph with swinging-arm rear suspension, the T110 came with a revised engine incorporating a stronger crankshaft, high-compression pistons, larger inlet valves and 'hotter' cams. The T110 remained in production into 1961, one of the most important developments along the way being the introduction on this model for 1956 of the aluminium-alloy 'Delta' high-compression cylinder head, which increased power and pushed the T110's top speed towards 120mph. Comprising a 1957 frame and 1956 engine, this T110 appears to have been purchased by its late owner circa 1989, which is when it was registered as 'RSU 377'. The machine is offered with dating/registration correspondence, old/current Swansea V5/V5C documents and a quantity of expired MoTs dating back to the early 1990s (most recent expired April 2006). The machine will require re-commissioning before returning to the road.
