Description

1975 Triumph 744cc T140V Bonneville
Frame no. 59678
Engine no. T140V NJ59678

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. Apparently a US-specification model, this 'Bonnie' has not been used for some time and will require re-commissioning and the customary safety checks before returning to the road. There are no documents with this Lot, which is sold strictly as viewed.
