1980 Triumph T140D Bonneville Special Registration no. CJM 585V Frame no. T140D CB26691 Engine no. T140D CB 26691 The final phase of Triumph twin development began 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. Coincidentally, 1979 saw the introduction of one of the Bonnie's final variants, the T140D Bonneville Special, which featured Lester cast alloy wheels and a stepped seat. This example of one of the rarer members of the Bonneville family previously belonged to the private vendor's late father. Last taxed in February 2011, the machine displays a total of 26,099 miles on the odometer (at the time of cataloguing/photography) and reportedly was running fine when last started in 2015. The rear subframe has been repaired and some chrome items replaced with stainless steel, and it would be fair to say that there has been some cosmetic deterioration while in storage. Following a period of inactivity and offered for restoration, prospective purchasers must satisfy themselves with regard to this motorcycles history, authenticity, originality, mechanical condition, completeness (or otherwise), sold strictly as viewed (engine turns over). Accompanying documentation consists of a current V5C, expired MoTs and some marque related literature. It should be noted that the V5C omits the 'T140D' frame and engine prefixes.
