Description

The original Triumph Bonneville was a 650cc parallel-twin (two-cylinder) motorcycle manufactured by Triumph Engineering and later by Norton Villiers Triumph between 1959 and 1974. It was based on the company’s Triumph Tiger T110 and was fitted with that bike’s twin 1 and 3/16 inch Amal monobloc carburettors as standard, along with that model’s high-performance inlet camshaft. It was initially produced with a pre-unit construction engine which enabled the bike to comfortably achieve 115 mph without further modification. Later a unit construction model was introduced which was stiffer and more compact, including additional bracing at the steering head and swing arm. The steering angle was altered and improved forks were fitted a couple of years later, which, together with this increased stiffness enabled overall performance to match that of the Bonneville’s rivals. Later T120 Bonnevilles used a new frame which contained the engine oil instead of using a separate tank; this became known as the oil in frame version. The T120 engine, both in standard configuration and especially when tuned for increased performance, was popular in café racers such as Tribsas and particularly Tritons.

With very period Burnt Orange over Silver paintwork and good chrome, this is a very nice example of this classic model – ready to enjoy right away.
