Triumph Bonneville T120


The Triumph Bonneville T120 was a Triumph Engineering motorcycle produced between 1959 and 1975. It was the first model of the Bonneville series. The T120 was discontinued in favor of the larger-engined T140, but the model was revived in 2016 with a number of updates.

The Bonneville name came from a popular racing venue in the Bonneville Salt Flats of Utah.

Sonny Fleisher brought this motorcycle back to America from England on the aircraft carrier where he was stationed during the Vietnam War. It was in a box and had to be assembled once he returned to the US. All of the components of this motorcycle are original.
