1963 Triumph 650cc 6T Thunderbird
Frame no. F5264
Engine no. DU855
One of the most important developments in the history of Triumph's long-running parallel twin was the introduction of unitary construction of the engine and gearbox in 1957, commencing with the 350cc 'Twenty-One' (later 3TA). The 500s went unitary the following year but it was not until 1962 that this more modern form of construction was extended to the 650s. A new alloy cylinder head was adopted at the same time and the engine/gearbox unit went into a new single-downtube frame with bolt-on rear subframe. Three 650s were offered initially: The Thunderbird tourer, Trophy trail bike and Bonneville sports roadster. Improvements were made on an annual basis: new forks and 12-volt electrics (the latter on the Thunderbird only at first) arriving for 1964 and a new frame with revised steering geometry for 1966. Mid-way through '66 the Thunderbird was dropped from the range together with the 3TA and 5TA tourers, their passing marking the final disappearance of Triumph's characteristic headlamp nacelle.

The Thunderbird offered for sale is in good cosmetic condition, featuring what appears to be period correct tank rack and side panels.
