Now look....we get it, you are not keen on Harleys.
A Harley is not an efficient brand of motorcycle. Just about any brand is going to be faster, handle better, stop better etc etc. Speaking personally, I wouldn't dream of buying a new Harley but then I wouldn't dream of buying a new BMW either.
For me, the joy in ownership of (an older) Harley is because of their inefficiencies. I like the agricultural feel of the engine that you feel beating beneath you, the way you have to hustle it into corners, the fact that gear changes can not and will not be hurried.
I also love the fact it can satisfy my fickle urges in changing how the bike looks with relatively little effort. I know that in twenty years (legislation notwithstanding) it will still be going quite nicely without being a corroded heap so long as I look after it.
Mostly though I love the way that when I ride one, I don't feel hurried, I don't need or want to ride fast and it leaves me feeling that all is well with the world. That is worth more than brake horsepower figures or razor sharp handling.
That's just me though.
