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 750. In 1977 Triumph introduced a special, limited edition Bonneville to celebrate HM Queen Elizabeth II's Silver Jubilee. This was basically the standard Bonnie enhanced by a red, white, and blue on silver finish, coachlined cycle parts, and a chromed timing cover and primary chain case.

This example of one of the more collectible of later Bonnevilles was purchased new by the lady vendor's late husband. Used sparingly, the machine has covered circa 12,000 miles from new and has been kept in dry storage, unused, for several years. Described as in need of sympathetic restoration, the machine is offered with Triumph Certificate of Ownership, the original sales invoice, an owner's handbook, and a V5C Registration Certificate.
