Triumph Bonneville T120

The Triumph Bonneville T120 is a British motorcycle built by Triumph Engineering from 1959 to 1975 and the first model of the Bonneville series. It was Edward Turner's last production design at the company. It was based on the Tiger T110, with a 649 cc parallel-twin engine and the twin Amal Monobloc carburettors that were an option on the Tiger fitted as standard. Launched as "The Best Motorcycle in the World" and aimed mainly at the American market, it began with a pre-unit engine, gained a stiffer unit-construction design in 1963, and later received an oil-in-frame chassis and a five-speed gearbox. Its best American year was 1967, and the 750 cc T140 superseded it after the Meriden sit-in.
