Are the ergos as bad as they look? All my joints hurt just looking at it.
Most of my late Dad's old bikes look like they were instruments of torture.Mind you, I would be pleased to have any of these three in the garage. These pics were taken in 1968 or 69. I wonder what became of them?
That's a 1950s BSA A7 (500cc) or A10 (650cc).
I see that it has a Siamese exhaust. My memory isn't what it should be, but I have vague recollections that some A7s had a Siamese exhaust from the factory to save money. So more likely to be an A7, perhaps?
After passing my test I used my Dad's 1959 A7 before progressing to a 1976 Bonneville.
I fitted a Siamese exhaust, but it certainly ran much better with twin pipes and silencers.

Ariel brakes, which, if memory serves, means that it's a 1956 or 1957 model.I see that it has a Siamese exhaust. My memory isn't what it should be, but I have vague recollections that some A7s had a Siamese exhaust from the factory to save money. So more likely to be an A7, perhaps?

Unbelievable beardy knowledge!
My first "big" bike in 1968 was an Ariel 350 and one of my mates owned a BSA with the same brakes.I can also tell you that
- the Triumph has sprung hub rear suspension (a design which is possible proof that Edward Turner was a heavy user of psychedelic drugs
)- the BSA Gold Star has the 190mm front brake that was apparently metric because the bosses wanted a new small brake for the scrambles model but the development team wanted a big brake for road racing, so they used millimetres on the assumption that management wouldn't know how big 190mm was
- the Norton is (most likely) an overhead cam International model, a race replica of its day
- the Triton has Gold Star "silencers"... BSA's concept of silence was remarkably flexible, even for the 1950s
I didn't have a beard until 1975.
