The 68 Bonneville stands as an enduring symbol of American motorcycling excellence, a legendary machine that has left an indelible mark on the hearts of countless enthusiasts. With its distinctive silhouette, thunderous exhaust note, and unmatched performance, the Bonneville has become synonymous with both freedom and adventure on the open road.

Historical Roots

The Bonneville's origins can be traced back to the early days of motorcycling. In 1958, Triumph released the T120 Bonneville, named after the renowned Bonneville Salt Flats in Utah, where Triumph motorcycles had set several land speed records. The T120 quickly gained popularity for its powerful engine and sleek design.

The 68 Bonneville: A New Era

In 1968, Triumph introduced the 68 Bonneville, a significant update to the classic T120. This new model featured a revised engine with increased displacement and a redesigned frame for improved handling. The result was a motorcycle that was both faster and more agile than its predecessor.

Unparalleled Performance

The heart of the 68 Bonneville was its 650cc parallel-twin engine. This air-cooled masterpiece produced 50 horsepower and 46 ft-lb of torque, providing ample power for both cruising and high-speed riding. The engine's distinctive exhaust note, characterized by its deep rumble, became an iconic sound associated with the Bonneville.

Coupled with the powerful engine was a revised duplex frame, which offered increased rigidity and stability while maintaining the Bonneville's signature "cradle" design. The combination of engine and frame resulted in a motorcycle that handled with precision and offered a thrilling riding experience.

Evolution of the 68 Bonneville

Throughout its production run, the 68 Bonneville received numerous updates and improvements. In 1969, Triumph introduced the Bonneville T120R, a more performance-oriented variant with a higher compression ratio, hotter camshaft, and revised exhaust system. This model produced 54 horsepower and was capable of reaching speeds of over 100 mph.

In 1971, the Bonneville received a major redesign, with all-new bodywork, a redesigned engine, and a new chassis. This updated model, known as the Mk II Bonneville, remained in production until 1972.

Legacy and Impact

The 68 Bonneville's impact on the motorcycling world cannot be overstated. It became a symbol of style, performance, and freedom, inspiring countless riders and manufacturers alike. The Bonneville's influence can still be seen in modern motorcycles, particularly those that embrace the classic British motorcycle aesthetic.
