Always a step ahead of their rivals, Triumph followed up the trend-setting Speed Twin 500 of pre-war days by being first in the field with a 650cc parallel twin, the Thunderbird, which was announced in September 1949. An interesting change to the Thunderbird for 1952 was the adoption of an SU carburettor in place of the original Amal, a specially prepared machine managing a staggering 155mpg at a steady 30mph on a factory organised economy run. The Thunderbird remained in production in fundamentally its original form until 1962, though with progressively updated cycle parts, one of the most significant developments along the way being the introduction of a swinging arm frame for 1955. Fitted with a slightly later (1951) engine, this particular Thunderbird is attached to a Zeppelin-style single-seater sports sidecar of unidentified make and comes with weather equipment for the 'chair'. We are advised that the combination was acquired in New Zealand by the current vendor around 12 years ago and has given good service over the years. Described as in generally good condition, the machine is offered with current road fund licence and Swansea V5C document. The provision of an SU carburettor is the only notified deviation from factory specification.
