The new BMW airhead...

Postby DerGolgo » Fri Jan 04, 2019 10:43 am

So, apparently, BMW built a prototype for a new boxer that may (or may not) come to market in the near future.
They seem to have noticed that, a decade ago, everyone got hot and bothered about "retro". So...
See for yourself:

Because "let's fuck with everyone!" they gave the prototype to a custom shop in Japan.
In case you are wondering: No, that engine apparently isn't much customized. It IS that large. It's 1,800cc!
And yes, it is air-cooled. Which would explain why they made it that ginormous, so that they can get sufficient power for modern traffic even while running at low-ish compression, and keeping the mix lean and emissions-friendly.

Heck. They didn't just go back to air-cooled OHV from 25 years ago. They doubled up and went back a full 50 years - look at those pushrod tubes! That camshaft is above the engine! It hadn't been there since the /5 came on in 1969.
Which is what suggests to me this might be genuine. The engine case looks rather /5 or /6 maybe, but the camshaft is in the entirely wrong place for that.

No detailed specs had been released at the time of publication. I would suspect, however, that the production bike will have fuel-injection.
Here's the article, from December 6th, so it's probably not an April-Fools:

I will try and find out more about this Monsterboxer.
If there were absolutely anything to be afraid of, don't you think I would have worn pants?

Return of the Cafe Racer (clicky) have more photos.

They call it a "concept engine". So handing such to a custom shop as market-research sounds fairly canny.

Could I still ride, I think I'd like the idea of knowing that a nice, simple, air-cooled, OHV boxer with all the displacement would be an option.

^^The front of the engine case looks like it may be the oil-cooler. FUCK. Can they make it more "OHFUCKINGWOW!"?

Not saying the rest of the engine is pretty. But that oil-cooler sure is.

Won't happen. The reason H-D is having to move away from Air Cooled engines is because part of the Emissions requirements is "Noise Pollution". H-D could meet the stringent Exhaust Pipe standards, but it was the sound levels that they couldn't meet. People thing that the exhaust note is the issue, but when you cancel out the exhaust note, you still have the metallic clatter (which let's admit it, we love) is still there.

IF BMW is able to get the engine to meet standards, then you can pretty much guarantee they paid someone off.

I recall similar confounders had beset the big four, when they wished to sell big singles. I've seen may a rattling metal with stabilizing metal ridges and bits of rubber.
Then there is material choice. Aluminium, surely.
But.
This is going to be a massively massive engine. I can imagine someonene signing off on slightly heavier alloys that have sound-dampening characteristics. Perhaps not high-carbon cast-iron.
I'm not writing it off yet.

This is what happens when Indian poaches your best designer, and you replace the budget you spent on trying to keep him around, on Harley Execs so you can boost your profits.

Oh FFS.

Well. Could I still ride, the idea of a brand new air-cooled, OHV boxer, with greater displacement than most passenger cars (over here) would excite me a bit. Definitely more exciting than any oilhead or the present crop of boxers.

I have no doubt. And I'm sure it would make me giggle, also, could I and would I ride it.
But I personally have a soft spot for insane engineering solutions.
"Emissions regulations won't let us get enough power out of an aircooled engine."
"Make it bigger then."
"We can, but we still won't..."
"I said bigger!!"
"We can make it bigger than any other, we still won't..."
"You're not listening to me. I said BIGGER!"

Test riding one of these would be something I'd travel to do, I believe.

I can dig that. I rode a KZ900ST to a Boss Hoss Dealer with a bunch of midlife crisis guys in Corvette's and Porsche's.
I would never own one...but hey...V8 in a motorbike...why wouldnt you ride one?

I like the engine, hate the rest of it.
