There isn't a regulatory imperative but there is an economic penalty. Practically every other country manufactures to metric standards so using our standards creates issues that are normally solved at added cost to American manufacturers.
Since most manufacturing is offshore getting tooling for instance in standard hardware sizing is a per unit added cost that does not provide any engineering benefit. If your primary focus is reduced cost at delivery then it doesn't make sense to invite increased cost with no improvement in product.
On the other side of the equation, exporting American goods that use standard fasteners to metrified countries costs the end users because maintenance tools are specials. Why buy an American product that comes with added burden when you can buy a comparable product that you are tooled to work on already?
Because it's a Harley, that's why. Because it's an American product steeped in the flag and ownership for many is a statement about being American. For many foreign owners Harley ownership includes showing solidarity.
Some things continue to exist just because they continue the iconography. Buicks have vents, HoJo's have orange roofs, Harleys have SAE.

We can't help it
We just keep moving
It's been that way since long ago
Since the stone age chasing the great herds
We mostly go where we have to go
