1979 Triumph 749cc T140D Bonneville
Registration no. YDE 598V
Frame no. T140D CA19507
Engine no. T140D CA19507

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.
The T140 offered here was purchased by the vendor over 2 years ago and is only being sold due to arthritic knee and dodgy back but since purchase it's been used and enjoyed whilst being run with some updated features such as the use of Mikuni carburettors (offered with the original carburettors), Norman Hyde 12 inch front disk, belt drive primary and clutch, electronic ignition and spin-on oil filter. The petrol tank and side panels were repainted as they were faded and needed refreshing. Documentation consists of a V5C, quantity of invoices, expired MoT's and a T140 Bonneville sales brochure. Offered with key.
