Why is that? H-D came out with a sport bike in the 70's, but it was ahead of its time. I rode one once, and it handled impressively.
But not, unfortunately, as impressively as everything else on the market at the time, and certainly not impressively enough for H-D to actually manage to sell any of them.
With the median age of H-D riders approaching 60, "handling" is no more to be expected from a Harley than from a Cadillac Coupe de Whatever.
I think one of the most popular Harley accessories these days is a chrome-plated holder for your cane.
I always liked the XLCR (Excelsior), but the Harley people hated them, and they sold about 11 of them. Today they're something of a collectors item.
