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 chaincase. This unregistered example of one of the more collectible of later Bonnevilles has covered only 78 miles from new. Presented in original condition throughout, the machine is offered with VMCC dating certificate, DVLA Form V55/5 and Triumph Certificate of Ownership listing one Thomas Watkins as first owner and stamped by supplying dealer Chas E Cope, of Smethwick, West Midlands.
