Introduced in 1959, the Bonneville quickly came to be flagship model in the eyes of the buying public. The single carb version, the TR6, the triple Trident and all the other permutations of the configuration, stem from the Bonnie, so it’s the model that captured the heart of the Triumph enthusiast for decades to come.

Developed over that time, first with unit engine and gearbox in the early 1960s, then improvements to frame and cycle parts kept the Bonneville competitive with the onslaught of the Japanese motorcycle invasion. Up to a point, at least.

Introduced in 1973, the T140V retained the classic styling of its predecessors, with modern technical advances. An oil-in-frame design with 750cc capacity, a 5-speed ‘box, and front disc brake was the most advanced, and best, according to Cycle World magazine, Bonneville made to date.

Triumph responded with the new Bonneville T140V in 1973. It was a refreshing return to more classic styling and there were bona fide technical advances like a front disc brake, an engine upgraded to 750cc and a five-speed gearbox. Cycle World said in its road test, “All told, the T140V is the best Bonneville to date.” Its 13.65 second quarter mile time made it the quickest accelerating Bonnie ever. Unfortunately, back in England matters were spiraling out of control and the workforce seized the Triumph factory. Few Bonnevilles made it to American shores for almost two years.

Hope was renewed when the 1976 line included an updated version of the 1973 T140V. It now had a rear disc brake and the shifting mechanism had been switched to the left side to comply with US safety regulations.

The bike offered was purchased about 25 years ago in boxes. It was subject to a ground up build with full mechanical restoration. Engine rebuilt, gearbox overhauled, and all cycle parts refurbished. The engine was installed in to the original, matching numbers frame. A lovely burgundy paint job was applied to the tank and chrome finishes were renewed as needed.

The bike was a regular rider in a small collection and was maintained accordingly. It was just gone-though by marque expert, Dean Collinson, giving it a comprehensive service to ready it for sale. Fresh tires, battery, cleaning of the carbs, a check through the spark system, all ensure a pleasurable ride.

The bike comes with a clean, clear California title. California resident buyers: the motorcycle has been placed in non-op status at the DMV so as to not incur any further registration fees.
