The 650 cc capacity production T120 Bonneville was replaced in the early 1970s by the T140 Bonneville, the same basic machine but with a 750 cc engine. Refined from the later ‘oil in frame’ version of the T120, the first few T140s, designated T140V, featured a larger-capacity engine of 724 cc, a five-speed gearbox, shortly after, the engine was further increased to 744 cc and front disc brakes were fitted
In 1975, along with engine modifications, the gear change lever was moved from right to left to comply with new regulations introduced for the American market. Various T140 models followed featuring modifications and refinements until production ceased with the closure of the factory in 1983.
One of the last incarnations of the 750 Bonneville the T140 special was clearly aimed at the US market although this examples appears to be a home market bike having been registered here 21st Oct. 1981. In generally good order the bike has had some recent top end engine work, bill on file, and comes with a new MoT until Jan. 2018.
