1953 Triumph Thunderbird

The Triumph Thunderbird was a British motorcycle introduced in 1949 and produced until 1966. To capture the American market, it used a variant of the Speed Twin’s parallel twin engine, bored out from 500 cc to 650 cc to give the added horsepower American customers demanded. The Thunderbird brought Triumph considerable publicity with Marlon Brando’s 1953 motion picture, “The Wild One”, in which he rode a 1950 Thunderbird 6T.
