TRIUMPHBonneville T 120 1959 - 1972

　　Bonneville was a success from the beginning. In 1959, the T120 engine was in fact a small T110 with some improvements but a few years later, the engine and gearbox were combined and the bike got a new frame. Later, the engine was enlarged from 650cc to 725cc, then the T140 was born.
