I had two motorbikes: a reliable Yamaha 125 bought in 1974 as an 18yo, on which I passed my test, and an unreliable but wonderful Triumph Bonneville 750 bought in 1979, on which I shot around the country (excluding the Isle of Man) at a generally sedate pace throughout the ’80s before selling it in 1991 for significantly more than I paid for it.
A pal of mine built a Triton which was a Triumph engine in a Norton frame, or the other way round. ‘Hybrid’ British bikes were popular builds: the Norton/Triumph BSA hybrids, Norbsa and Tribsa being two examples.
