The Triumph Thunderbird was a British motorcycle introduced in 1949[1] and produced in its original form until 1966. The name was used thrice more for new and distinct Triumph models.

To capture the American market, the 6T Thunderbird used a variant of the earlier Speed Twin's parallel twin engine, bored out from 500 cc to 650 cc to give the added horsepower American customers demanded.[2]. The concept of enlarging the Speed Twin, the Thunderbird name and its 'paper dart' logo were thought up by managing director Edward Turner on one of his regular trips to Triumph's operations in the USA. The 'paper dart' logo was embossed onto the chain case cover on Thunderbirds from 1955 to 1962 and can be seen upon closer examination on the supplied photograph. Previously, it appeared as a decal on the headlamp nacelle.

Triumph obtained further publicity with Marlon Brando's 1953 motion picture, The Wild One, in which he rode a 1950 6T Thunderbird. In the book Triumph Motorcycles In America (Brooke/Gaylin), there is reproduced a letter from Triumph's importers objecting to the producers as to the use of their machine in this film about rowdy motorcycle gangs.

In 1962 the cost of a new Thunderbird was £278

What a beautiful Thunderbird - I am glad they have kept that name through the years - it has represented some amazing bikes!

Didn't Steve McQueen use one of these in the motorcycle scenes from "The Great Escape?"

Baron's Life said... is also very enjoyable to has a different sound to it than current day models

Joker, The great Escape and Steve Mc Queen is what got me hooked on motorcycles...when I saw him take that jump in the movie, I was hooked forever.
Steve Mc Queen used a modified 1962 Triumph TR6 for that stunt...actually he did the stunt himself...he was a great motorcycle rider, all his life.
