New CSC TT250/Hawk BETTER than 1970s Japanese bikes?

[enewmen]

I'm keen on the TT250/Hawk because it's similar to a bike I had in the mid 80s and I wished I kept it and took better care of it.
Anyway, the point is: IS there reason to think the "clone" TT250 and similar CG250 bikes are better- MUCH better than the bikes 50 years ago?
In the 2020s compared to the 70s:
Better materials.
Better quality control.
More precise machining.
Better understanding of engine design/physics to "tweek" old designs.

Transistorized ignition.
Better understanding of maintenance (and people today care more).

People today ride & keep bikes for far more mi/km than decades ago?
My guess is a new CG250 clone bike will last much longer than if I tried to keep an original if I did all maintenance correctly.

I know I'm just thinking without facts, but does all this seem correct??
If I get a TT250, I hope to keep it for more than 30k miles and take the bike to very remote places.

Thanks!
