OHC engines have higher rev limits and produce good HP but at higher RPMs.

I don't see they've changed their "unique" product .
I see it as they've added new .
Big Twin isn't going anywhere any time soon.
(regardless what the HennyPennys have to say)
as long as there's a market, the sky won't fall .
my point is, I don't know any good reason they can't "add" product .
Pret'near every manufacture has different class and style bikes with different motors.
am I'm naďve to think Harley is a top tier manufacture that can design and build some great bikes?
If not...why wouldn't folks looking for a second bike to scratch a different itch want it to be a Harley rather than a German, Austrian, Japanese, Italian or British outfit?
what I don't understand why would anyone see that as a "bad" thing?
I get it if your concern is their big twin cruisers and tour models will disappear and be no more.
But that's not going to happen.
Not in my lifetime anyway
(presuming me and MoCo make it another 15-20 years)

This is exactly right. Harley v-twins are pushrod engines, which produce low end torque, but the rev limit is lower due largely (I believe) all the moving parts. Lest you think pushrod engines are old technology, think again. The new mid-engine Corvettes are pushrod engines and they rival European super cars at a fraction of the price.
OHC engines have higher rev limits and produce good HP but at higher RPMs.

There will always be Harley touring bikes, and a market for them, until all the highways & byways are turned into bicycle paths and gasoline runs out.
If I live long enough, my last gallon will go into my bike.

Yes, but it really is piston speed which is a function of the length of the stroke.

So Ive been reading about the revolution max engine. I see that it redlines at 9500. It also produces 150 hp and 94 of torque at 1250cc. Could this engine efficiency be used in the touring models as well? I guess Im asking is whats stopping them from putting it in. That is way more power than my 103.
