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. The Thunderbird remained in production in fundamentally its original form until 1962 (though in 1952 the Amal carburetor was switched out for an SU in search of economy!), 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.

This bike was hot rodded from its day one by a mechanic at the then Louisville, Kentucky Triumph dealership as a fast street and occasional drag bike complete with factory competition parts. In the late 1960s it was 'put away in storage' for the next 40 odd years. Between 2012 and 2015 it was rebuilt
by the seller.

The overall styling of this Thunderbird is now that of the popular 'bobber', a style that seemingly has never gone out of fashion. Its engine was completely rebuilt with new MAP rods, 9.5 to 1 +.030 pistons, 'Q' cams, valves, bearings and gaskets together with the gearbox to which was added a new primary drive and clutch. The bike runs a total loss lights and horn system but is set up for the addition of an original-style generator and voltage regulator. The front brake carries a next-year air scoop and the fuel tank is a one-year-only 'Tri-Cor' competition-style; the paint, professional Midnight Blue plus clear coat.

We offer a storied motorcycle that is, today, a wonderful opportunity to enjoy as is or to further develop it your way.
