The final phase of Triumph twin development began in 1972 with the first appearance of the 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 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 MCN's 'Machine of the Year' in 1979.

This T140V was purchased by the current vendor from P.M. Motorcycles of Harleston, Norfolk in October 2020, since when it has covered only some 65 miles (copy bill of sale on file). The machine retains its original paintwork and supplying dealer's decals on the side panels, and currently displays a believed-genuine total of only 3,565 miles on the odometer, seemingly verified by accompanying MoT certificates. A full service was carried out by Ace Classics in July 2021, which included renewing the clutch and fitting correct 6-volt ignition coils (bill on file). Last run in December 2021. Offered with a V5C.
