Most of them have been. Some have been oil-cooled and I've had some
water-cooled, too. The most automotive was my '86 BMW K75; water
cooled with a dry clutch and shaft drive; basically a BMW car
four-cylinder engine flopped on its side and a cylinder lopped off.

What difference is that?

I can only think of one:

For pre-Evolution Harleys (like my '56 FLH) it's recommended to let
them idle a minute or two to allow the cylinders and heads to warm
slowly with minimum of applied stress before riding off. If that's
not done, the difference in expansion rates between the cast-iron
cylinder and aluminum head can result in oil weepage through the head
and base gaskets which will get worse over time. This is a case where
a two or three minute rule of thumb applies.

Any other engines I know of, a two or three minute idling warmup
should be an exception rather than a rule of thumb. I can't imagine
why I'd ever do it on a motorcycle; it's not like I'm waiting for the
cabin to warm up and the windshield to clear off ;^)

If my air-cooled motorcycle engines are exceptions, I'd be glad to
learn about those differences. Or for other car engines too, for that
matter . . . .
