I don't live inthe outback, bad as our roads are here in UK ,they have never been frame breakers.

It would have been a different story before tar was invented ?
Which was only in the 1920s.

I can recall our street being tarred in suburbia, and that was a LONG time after the 1920s.

Nortons actually have quite a record of  steering head woes.
Featherbeds had to have gussetts welded around the steering head tube.
And early Commando frames were recalled to be redesigned with a strengthening bar under the tank.
