Edward Turner then ran Triumph and was resistant to any new models that were not his own design. And while Triumph was part of the BSA Group, Turner ran his division as his personal fiefdom, resisting all efforts to introduce commonality in the BSA and Triumph ranges. Though there was no love lost between them, Bert Hopwood had worked with Edward Turner as designer, draftsman and engineer for much of his career. It was Hopwood who often re-engineered Turner's designs to make them practical and reliable. By the early sixties, Hopwood realized a new engine would soon be needed to replace the aging parallel twins.

Hopwood and his assistant Doug Hele drafted a three-cylinder engine: effectively a unit-construction Triumph 500 twin with an extra cylinder, giving it 750cc. But Turner was opposed to the triple and the project went no further until Turner retired in 1964. Hopwood and Hele fitted their engine into the Bonneville frame and cycle parts. The prototype worked well and looked great but senior management was unimpressed - until word leaked in 1967 that Honda was working on a 750 multi. The project was revived, with the engine redesigned and fitted in a new frame using cycle parts from the existing 650 twins. In all, only around 7,000 Rocket 3s were built, including 1,000 1971 models and 200 1972s This BSA US Export Rocket 3 was manufactured in 1972 and is one of the 200 produced in that year. This matching numbers machine has a UK registration, GYX618J, and was imported into Guernsey in 1973. It is presented in beautiful condition having been rebuilt approximately eight years ago to original specification by Carl Rosner.
