Interesting intake/exhaust port relocation. Icing on the intake probably isn't as big a big deal on these guys as it was on prop driven aircraft, eh?

You don't get icing on injected engines because the fuel is injected into the port below the throttle body, and there's no venturi in the way.

I just love that BMW fell into the trap the metric water cooled cruisers have.
Fake fins. Nice touch.

The relocated intake will be nice to those who need more leg and shin room.

Somewhere in the countless threads on this bike I read that only the heads are water cooled, the cylinders are air cooled so the fins are functional.

Yea functional in that there is some heat exchange but the real meat of cooling happens around where the real meat of the heat is produced, the head. if you look at the photos it shows fin up to the valve covers.

The styling department is going to work awful hard on making a good looking Roadster out of that motor with the throttle bodies on top of the barrels and two radiators to hide.

It's not called "fake fins", it's called "Heritage"!

The fins are still used for cooling.. the liquid cooling, according to BMW, provides only 35% of the cooling.. So it still is air / oil cooled as well.

The real headline of this motor should be the integrated gearbox and the wet clutch. The best thing BMW could to to a motor is make less places to leak from lol.

Au contraire...

Think about it... it's not the fuel that freezes in the intake tract; it's moisture that's already present in the air. If the humidity is high enough, and the OAT is low enough, the added evaporation from pressure drop can sometimes drop the air below freezing as it heads toward the intake valve(s).

Where the fuel is added to the airflow has zero effect on "carb" icing, and the throttle plate creates a lot of vacuum downstream unless it's WFO. .

You mean like the oil coolers on an R1100/1150/1200R?





I don't think that will be an issue.

Fins (and the rest of the engine case) provide over half the cooling on this motor. Water only cools the top of the combustion chamber, around the heads and valves. Keeps the water system small and light.

So anyway...the fins quite functional and necessary.

+1

THAT is the really big news here...finally joining the "unit construction" modern age. No more car clutch in a motorcycle. One oil fill, slipper clutch, quieter, smoother, lighter...best boxer motor refinement since the oil cooler. Eases the engine cooling requirement, too. Smaller water system is a nice byproduct...

And...now they are set up to drop a CVT (or electro-mechanical) in there and offer paddle shifting/automatic. For their target audience, that will be a big seller.
