Riding where it's hot!
The 1150R will have an advantage if the pavement gets really nasty, mostly due to para/telelever suspension.
KBasa, Doesn't this show the bike has a paralever suspension?

From what I've read (and intuitively) the Paralever helps mitigate driveshaft effects. That's why you'll see it on BMW's and Guzzi's. The R1200C doesn't have it as the driveshaft is long enough to reduce most of the driveshaft 'jacking'. My first bike was a Suzuki Intruder and the driveshaft effects were much pronounced. (no paralevel or such compensation)
No need for it with Belt or Chain drives bikes. Different dirve train forces. (And no lever in that pic)
Check this article for a pic of monolever (swingarm) vs. paralever. http://www.largiader.com/paralever/
KBasa, did you find that the plastic skin parts felt thin, cheap and brittle? When you knock on it, it sounds brittle. I keep waiting to hear a report from someone who dropped an F800. The material feels to me like styrene that will "explode" in a parking lot tip-over. Just wonderin'.
The driveshaft effects of the r50/2 I drove were called "torque steer". I see many parallells between the center mounting arm and the outer belt dirive of the F800 to the paralever, you are right this is isn't one.
Then again, I will not miss it as the F imparts no torque steer. The pic shows rear suspension is certainly beefy enough. But it is a single-sided drive, "fork assembly as it attached on both sides.
Thanks for the link, I have bookmarked it.
The F800 final drive system is not a paralever in any way. The paralever was developed to reduce "shaft jacking" a phenomenon the causes the rear end of shaft driven bikes to rise under acceleration and drop under deceleration. A paralever has two universal joints to allow the final drive unit to work independently of the shaft.
"Torque steer" is a symptom of front wheel drive cars. In those vehicles, torque from the driving front wheel can produce feedback in the steering that can cause the car to dart from side to side as power is applied.
The F800 final drive system is a very straightforward swingarm with belt drive and directly mounted shock. There's nothing fancy here. All swingarms are, to some degree, the same. They may be single sided, they may be more traditional and carry an axle from both ends. They may have one or two shocks, mounted in a variety of ways. But they all have two mounting points, one on each side of the frame, or as is the case of this bike, the rear of the case.
