First introduced in 1937 as a '500', the Triumph twin underwent one of the longest development processes in motorcycling history before emerging as a '750' some 30-plus years later. This final phase of Triumph twin development began late in 1972 with the first appearance of the new enlarged-to-750cc version of the Bonneville, the increase in bore size necessitating a new crankcase to accommodate the larger barrel. 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 and was voted Motor Cycle News 'Machine of the Year' in 1979. A 1978 model fitted with a 1977 engine, this T140 Bonneville currently displays a total of 13,928 miles on the odometer and has been in the vendor's family since May 1984 when it was purchased by his father. Described by the vendor as in generally good condition, the machine is offered with MoT to March 2013 and Swansea V5 document. The front mudguard and silencers are obvious non-standard features.
