I've been baffled for years as to how Harley change something minor, like different bars or "black crackle engine finish" and call it a new model.
There are a few actual Harley models, with different engines and suspension etc. then the rest of the "range" is just minor variations on a theme, achieved with paint, options and accessories, they are not different models in the true sense.
Haven't ridden one for years, a new 883 Sportster in 1977 actually. It vibrated so much the wiring connectors came apart and it broke down, more than once. It didn't go, stop or handle either, never looked at one since.
Harley owners may spend a fortune on (mainly chinese made) Harley accessories making their bike look different to the others but the trouble is all the riders look the same! I agree with some other comments, most are too up themselves or consider themselves too cool to acknowledge other bikers.
Visit a Harley dealer on any other bike and, luckily you'll be ignored by the stereotypical dress-alike Harley crowd, leaving you free to try and work out how a naked V twin Sportster is£7k and a similarly naked but slightly larger V twin FatBoy is £16,195!
