Maybe only a Fiat 500, Subaru 360 or Simca 1100 could compare. (Honda 600s are too advanced.)

ugh.
Even mention of SIMCA (wrenched a friend's piece of crap
repeatedly 49 years ago) makes anyone familiar with the
things shudder.

My nominee for worst is Fiat, AKA "Fix It Again, Tony." They've been consistently
at or near the bottom of the list for reliability for over a generation. Such
consistency!

I bought a used one. At the moment I closed the deal, I got a bad feeling in
the pit of my stomach. (Really, that's no exaggeration.) Within a month, that
premonition was confirmed in spades.

Are the old Suntour Cyclone bottom brackets and the old Shimano bottom brackets the same standard? Can a Shimano cup and cone bottom bracket be used with a Suntour Cyclone crank? Can a Shimano cartridge bottom bracket be used with a Suntour Cyclone bottom bracket?

Cheers

Suntour and Shimano square taper cranks both used JIS tapers.

I wrangled my X1/9 for nearly a year with many new and
interesting failures until I gave it away.

Yes, insofar as frame/cup threads match and spindle
dimensions are the same or close.
(IIRC Cyclone and New600 are same length but not certain)
They are both the same taper section and both are symmetric.

No, Shimano UN type units are a different taper section.

Indeed some did, but in the classic era most did not.

Whoopsie. Meatware error on my part.

New 600 are the revisionist JIS section.

Okay. So a Suntour Cyclone crank won't fit properly onto a Shimano UN sealed cartridge bottom bracket?

Would a Suntour Cyclone crankset fit properly onto a circa 2001 Campagnolo Veloce sealed cartridge bottom bracket?

Thanks again and cheers

I don't know but I suspect the later spindle may be too
short. Designers moved to curved cranks= shorter spindles
(while keeping the same chainline) during that period.
