Triumph Motorcycles 6T Thunderbird (1958)
Vehicle descriptionThe Triumph Thunderbird is a British motorcycle that was introduced by Triumph in 1949 and produced in many forms until 1966. The name was used three more times 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. The 6T Thunderbird was launched publicly at Montlhery near Paris, where three standard-production bikes were ridden around a circuit by a team of riders who between them averaged a speed of 92 mph (148 km/h) over a distance of 500 miles (800 km).
