Following the enormous success of the Triumph Bonneville in the 1960s, the bike was in need of an update. The introduction of the “oil in frame” model was quickly followed by a power increase attained through a re-bore taking the capacity to 750cc to compete with Honda and Norton. Other improvements included a new ten-stud cylinder head, triplex primary chain, stronger 5-speed transmission, and a disc front brake. Despite the age of the basic design and strong competition, the Bonnie remained for many years the UK’s top-selling ‘750’ 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. 1,000 were produced for the United States market, 1,000 for the UK, and a further 400 for Commonwealth countries. 

The Silver Jubilee model offered is quite a rarity in the US. An imported UK spec machine with larger gas tank, the odometer reads only 10,400 miles from new, believed to be accurate and presents exceptionally well. With a nice patina, the matching numbers bike is in generally excellent condition throughout.

Serviced and ready for sale, the bike is in fine tune, runs well and all cycle and electrical systems work as they should.

The bike is accompanied by a clean, clear California title in non-op status.
