One of the more collectible of later Bonnevilles • Never registered or used • 100% original Triumph entered the 1960s with its larger twin-cylinder models recognisably similar to the first Speed Twin of 1938. Unitary construction of engine and gearbox was already a feature of the 350 and 500 twins though, and that innovation duly appeared on the 650s in 1963. The café racers' favourite since its launch in 1959, thanks to its lusty acceleration and a top speed approaching 120mph, the Bonneville continued in this new form as Triumph's top-of-the-range sports model. The final phase of the Triumph twin's development began in 1972 with the first appearance of the new 750cc version of the Bonneville, the increase in bore size necessitating a new crankcase to accommodate the larger barrels. Other improvements included a new ten-stud cylinder head, triplex primary chain, stronger transmission, and a disc front brake. A five-speed gearbox, introduced on the preceding 650 Bonneville, was standard equipment on the 750. Despite the age of the basic design and strong competition from Japanese and European manufacturers, the Bonnie remained for many years the UK's top-selling 750cc model and was voted Motor Cycle News 'Machine of the Year' in 1979. In 1977 Triumph introduced a special, limited edition Bonneville to celebrate Her Majesty Queen Elizabeth II's Silver Jubilee. This was basically the standard Bonnie enhanced by a red, white, and blue on silver finish, coach-lined cycle parts, and a chromed timing cover and primary chain case. This example of one of the more collectible of later Bonnevilles has never been registered and remains in 100% original condition, even retaining the trip meter instructions and 'no oil in tank' warning stickers on the instrument lenses. Needless to say, all of this special model's identifying badges and decals are still in place, while deterioration over the course of the last 40-plus years appears to have been minimal. There are no documents with this Lot. A unique opportunity.
