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 chromed timing cover and primary chaincase. Owned by the vendor since new, this original and unrestored example of one of the more collectible of later Bonnevilles has covered a genuine 115 miles only. Presented in effectively ‘as new’ condition, the machine is offered with current MoT, Swansea V5 registration document and its original Triumph Certificate of Ownership.
