Why Evo?
I don't know if Harleys much better when it comes to spitting out different models or variations of existing models. I know I can't keep track of them all. Things definitely were much simpler in past decades.

One is a strong concept of "kaizen", a strategy of never-ending small efforts for "improvements" which makes a parts man's life hell because one part will only fit one year's releases.
You can see H-D's 20 year long steps in the second curve.
The other element is a kind of love of novelty or testing out new ideas in the market place. That is to say, they dump a dozen or more new and very different products in the marketplace to see which one catches, and then run with it dropping the others. If, unfortunately, you like a product which was not popular, you'll never see another part for it ever again.
It makes for an interesting and eclectic collection of vintage motorcycles, and some very cheap second hand vehicles, but not a very fecund aftermarket.
I like H-D's Soviet era "uni-wagon" approach to perfectly adequate transportation. It's very rational and it's allowed a rich aftermarket. All it really needed/needs was to be engineered to slightly higher standards, a standard equal to its paint jobs --- but that's the accountants' and management's fault, and not the workers or engineers.
Or something ...
Harleys from the same era still have some limited dealer support, very rich aftermarket support, and most of them still on the road and being ridden.
I'm going to say that Harley-Davidson's strategy was ultimately more successful.
They were brought down by the accountants IMO.

I suppose the Japanese/Asian equivalent of the H-D, in terms of both utilitarian transport and customization would a 125cc 4-cycle single, or even a Cub. Over 60 million units shipped, and is still in production today.
I'm not dissing it but H-D itself controls a narrow niche in a fairly narrow socio-economic band, and it's pretty much US only. I appreciate it, I like the concept of sticking with one thing that is perfectly adequate and working, but I think we need a better definition, something like the "most sustainable engineering eco-system" (for big people with big roads). You couldn't run an H-D on half the road the Cubs manage (nor carry the usual 5 passengers and a couple of chickens).
These are the real dangers to its continued existence though, demographics and economic tendencies --
Would the market have have consumed a non-pushrod engine like the X Wedge? Belt driven OHC, 3 or 4 valves per head? Water cooled top end? Nova?
Like them or not, Victory did resolve a lot of technical legacy problems in the engine design but that would have broken more of inter-exchangeability.
From an EPA point of view, what was/is the real problem with the Evo engine?
