Led passing lamps as well...

what it sounds is ugly and about tenth grade.

So what, that's not unusual. Can you not clearly see the water flow in the illustration

Do we know BMW's internal name, number, or other designator for this new engine? That might help to suggest a name we use.

Honda did that on their SuperHawk and VFR800 in the late 90's. I wouldn't anticipate much of a problem with it.

The high beam is on the left cluster, at the front, you pull it in with your index finger to flash or push it out to keep it on. It's not visible in the picture, as it faces the front of the bike.

Not sure if I like that, at least I'd like to see the switch.

The gearbox/transmission is remarkably over-complex. Power from the crankshaft must go through four pairs of gears before reaching the shaft in the swingarm. (Versus only two pairs, in the current & past boxers ~ certainly one of the reasons contributing to the current fuel efficiency superiority over the transverse-crankshaft "big shafties" like the S10 and the Explorer.)

The extra friction must worsen fuel consumption a bit ~ probably more noticeable at lower throttle openings.
Maybe the slightly higher compression ratio will counteract that, to some extent.

Still, you can see that the engineers were aiming at compactness of design, and were okay with some compromises in order to achieve it. (In the face of an un-compact cylinder layout which had to persist.)

Transmission efficiency aside . . . it all looks very impressive.

The S10 afaik has been reporting better economy than the boxers, despite having to turn the power twice AND using a hypoid rear end.

So while it may be true that there are more meshes in the new tranny than the old one, this factor doesn't necessarily guarantee increased fuel consumption. Factors that suggest better economy : no separate chain drive for balance shaft, gear driven rather than belt driven alternator, water cooling.

The electronic suspension on the 2010-2012 Duc is by Ohlins. For 2013, both BMW and Ducati have gone with Sachs to get their "semi-active" technology.

And FWIW, the Sachs system does NOT have electronic pre-load, which was the source of the troubles with the Ohlins units (with the Ohlins, the pre-load servo fails, not the damping bits).

That is going to make heat management an issue in the evolution of the RT. Glad I bought the Camhead version.

I thought the same thing, but look closely at the pics and you'll see plastic ducting that forces the hot air coming through the rads out away from the rider.

After looking at the pictures and let it all sink in I must say I like the looks of the new GS as the new engine is as good of a design for a motorcycle engine as it gets !
The 2 cylinder boxer was always a perfect motorcycle engine for everything but roadracing purposes with it's balance,low center of gravity,no crankshaft gyro to affect handling in a negative way,ease of maintenance and unique ability to protect bike and rider in case of mishap.
Now they made the intake runners straighter to get more power and put the clutch where it doesn't cause expensive bills anymore if it needs to be replaced.
No alternator belt anymore that can break or needs to be replaced.
As for accessability it sits under a cover that should beeasy to access after the tank is taken off.
As for the valve adjustment it looks like the cams have to come off because the followers don't slide to the side anymore like in the camheads.But even this should be easy as no timing chain has to come of with the gears driving the cams.
Should be a great engine powering a 135hp/nm R1200RS in the near future...
My guess is that a water-boxer R1200RT and R1200GS-ADV are next for 2014 out in autumn of 2013...

Sure there is. look at the diagram, water flows around the valves

As mentioned, Honda did this with the VFR, RC51 and superhawk. They had limited success (i've owned 2 VFRs), mainly due to them orienting the radiators sideways and the way the fan pulled air (causing no airflow to the radiator when moving while the fan was on).

BMW had a similar setup on the K1200RS/GT, although they had 2 small fans (1 on each radiator). I think some of the KTMs run a similar setup to this (2 rads, 1 fan) and some people upgrade to a second fan.
