The Bonneville T120 was Edward Turner's last production design at Triumph. Launched in 1959 by Triumph as "The Best Motorcycle in the World", the Bonneville T120 was aimed mainly at the lucrative US market where enthusiasts were demanding extra performance, but was developed so quickly that it was not included in the 1959 Triumph catalogue. 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 the same twin 1 and 3/16 inch Amal monobloc carburettors as standard, together with the high-performance inlet camshaft. It was initially produced with a pre-unit construction engine which enabled the bike to comfortably achieve 115mph without further modification. Later a unit construction model was introduced, which made it 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 Bonneville 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.

This matching numbers Triumph Bonneville T120 was purchased by the vendor about ten years ago as a restoration project which was completed in 2012. The inspiration and the result is presented here as a production racer with reversed handle bars, moved foot rests, a one gallon oil tank and rear number sets. Finished in the correct two tone blue this T120 has covered only 100 miles since being restored and is supplied with a V5C registration document, the old MoT test certificate and a file of invoices amounting to about £6,000 spent on the rebuild. This is an opportunity to purchase a fully restored Triumph Bonneville, which would grace any motorcycle collection.
