Thanks for the link; that's good.

Maybe good advice, but if everybody did this they would sell zero of these bikes and go out of the motorcycle business.

Well, maybe new for the R bikes, but according to Wikipedia “An early experimental 200 hp Clerget V-8 from the 1910s used a sliding camshaft to change the valve timing.”
I wonder how this was accomplished in the 1910 design? Is it similar to the BMW implementation? Any antique aircraft enthusiasts out there?

Press kit is out for the R1250GS and the R1250RT: https://www.press.bmwgroup.com/global/article/detail/T0284913EN/the-new-bmw-r-1250-gs-and-the-new-bmw-r-1250-rt
The new BMW R 1250 GS and R 1250 RT – the fascination of travel and touring in a new dimension of engine power.
For more than 35 years, the flat-twin boxer engine in the BMW Motorrad GS and RT models has stood for distinctive, powerful and reliable propulsion when it comes to setting off on an extended tour or a long-distance journey – or simply enjoying the satisfying pleasure of a short weekend trip. For more than 25 years, BMW Motorrad has used 4-valve technology, combined with electronic fuel injection and closed-loop catalytic converter technology in order to achieve the best possible power and torque delivery, efficiency and environmental compatibility.
Further advanced boxer engine with BMW ShiftCam Technology for an additional increase in power across the entire engine speed range, reduced emission and fuel consumption levels, optimised running smoothness and refinement.
With the extensively further advanced boxer engine, the new R 1250 GS and R 1250 RT not only achieve a whole new level of power and torque. It was also possible to significantly optimise refinement and running smoothness – especially within the lower engine speed range. What is more, the new engine offers improved emission and fuel consumption levels as well as a particularly satisfying sound. For this purpose, BMW ShiftCam Technology has been used for the first time in the serial production of BMW Motorrad engines: this enables variation of the valve timings and valve stroke on the intake side. In addition, the intake camshafts are designed for asynchronous opening of the two intake valves, resulting in enhanced swirl of the fresh, incoming mixture and therefore more effective combustion. Other technical changes to the engine relate to the camshaft drive – now taken care of by a toothed chain (previously a roller chain) – an optimised oil supply, twin-jet injection valves and a new exhaust system.
Two riding modes, ASC and Hill Start Control as standard.
There are two riding modes available as standard in order to be able to adapt the motorcycle to individual rider preferences. The standard Automatic Stability Control ASC ensures a high level of riding safety due to the best possible traction. The set-off assistant Hill Start Control is likewise a standard feature in both models, enabling convenient set-off on slopes.
Riding Modes Pro, featuring additional riding modes, Dynamic Traction Control DTC, ABS Pro, Hill Start Control Pro and Dynamic Brake Assistant DBC (new), available as an optional equipment item ex works.
The option "Riding Modes Pro" is now available as an optional equipment item, featuring the additional riding mode "Dynamic", Dynamic Traction Control DTC, and in the R 1250 GS also the riding modes "Dynamic Pro", "Enduro" and "Enduro Pro". DTC enables even more efficient and safe acceleration, especially in banking position. ABS Pro (part of Riding Modes Pro in the R 1250 GS, a standard feature in the R 1250 RT) offers even greater safety when braking, even in banking position. The new Dynamic Brake Control DBC provides additional safety when braking, also in difficult situations, by avoiding unintentional accelerator activation. By means of intervention in the engine control, drive torque is reduced during braking so as to make full use of the braking power at the rear wheel. This keeps the motorcycle stable and shortens the braking distance.
Electronic suspension Dynamic ESA "Next Generation" with fully automatic load compensation, now also for the R 1250 RT.
With the optional equipment item BMW Motorrad Dynamic ESA “Next Generation”, damping automatically adapts to the situation according to riding state and manoeuvres, and there is also automatic compensation in all load states. This allows finely tuned adaptation of the motorcycle to riding states, achieving optimum damping comfort and a very stable ride response – this is now also available for the R 1250 RT.
LED headlamp for the R 1250 GS as standard and LED daytime riding light for both models as an ex works optional equipment item.
The new R 1250 GS now features the LED headlamp as standard. In addition to this, the LED daytime riding light is available as an optional equipment item for both the R 1250 GS and the R 1250 RT, which has halogen headlamps.
Connectivity: multifunctional instrument cluster with 6.5-inch full-colour TFT screen and numerous features as standard in the
R 1250 GS.
The new R 1250 GS now has the equipment feature Connectivity as standard including a 6.5-inch full-colour TFT screen. In conjunction with the standard BMW Motorrad Multi-Controller, this means the rider can access vehicle and connectivity functions particularly swiftly and conveniently.
The R 1250 RT is fitted with a large 5.7-inch TFT colour screen. This is supplemented with an analog speedometer and rev counter.
Intelligent Emergency Call as an ex works option.
Ensuring the fastest possible assistance in the event of an accident or in situations of emergency and danger can save people’s lives. The optional equipment item Intelligent Emergency Call summons assistance to the scene as quickly as possible. As before, this feature can be ordered for both models.
BMW Motorrad Spezial – high-quality customisation features as optional equipment items ex works.
BMW Motorrad Spezial offers a range of iconic customisation features that enhance both performance and value, available as optional equipment items ex works. The focus is on harmonious integration in the vehicle as a whole, use of the very highest-quality materials, elaborate manual workmanship and characteristic attention to detail.

That was odd, I could not open a You Tube video but I could see the Face Book video and I'm not a Face Book user.
The Face Book video didn't have any info I have not already read.
I noticed the GS on the stand had a new exhaust but the exhaust in the video was the old style.
Edit: I see the GS HP on the stand is a new Akrapovic.

On the RT, I didn't see a TFT display. The discussion with the product manager indicated that the "Rain" mode is gone. "Road" and "Dyna" are still there. Road adapts to any conditions, thus making "Rain" superfluous I guess. ESA becomes fully automatic. Bike adapts to the load without driver/rider intervention. Hill Start Control can be made automatic too.
Maybe there's more but the technical quality of the video wasn't too good for me.

Read that, I was curious if the You Tube video was different than the Face Book one.
