Correction, I think it is three if you include the quote from BIKE magazine that MarkJenn posted previously, I had just pasted the incorrect quote...

Just to put some specificity to this discussion of possible handling issues with the new GS, here is the quote from the Bike magazine article:
"The only unpleasant shock during the while 280-mile ride is a tankslapper so violent it snaps the lockstops off the frame. BMW chassis engineers seemed shocked to hear of it, claiming they never experienced anything of the sort in five long years and one million kilometers of testing. It does seem that I just happen to have stumbled on exactly the wrong combination of speed and road surface at the wrong time. Assuming it really is just a one-off - which, in all fairness, would appear to be the most likely explanation - then the new R1200GS is a remarkable machine."
You guys can argue about whether worrying about something like this with the amount of data we have is prudent or chicken-little.

Well I can't say I'm surprised. They have been shocked for years about final drive failures.

Anyway if it is a real problem it will be fixed....Eventually...Maybe..

"Motorrad" has its 2013 review "Wasser Marsch" or "bring on the water".
Oh, I don't even have to read it, the new GS is perfect in every German magazine :-)
...I was wrong, Motorrad couldn't test the GS in South Africa and therefore published an Italian review from "Motociclismo"...
Perfect but they've noticed off-road front end instability (handlebar shake) at 120-150Km/h (thinner fork tube/new stiffer frame) combination issue?

Maybe. Stroms tended to do that a bit. Thinnish forks, stiff frame. Maybe a fork brace will help.

Motociclismo's online review

Motociclismo has a review online, starting here.


Its reviewer also says something about the way the bike behaves on corrugated off-road surfaces, with the dynamic damping. Here it is in Google Translate:

"Where the GS is in difficulty are small undulations in rapid succession , perhaps due to the reduced suspension travel and accomplice probably the stiffening of the frame at the front, the Telelever breaks down on bumpy at speeds between 120 and 150 km / h, and the front tire hard copy to the ground by returning some sbacchettata steering."


Somebody who can read Italian might offer us something more accurate from the original:

"L’unico frangente dove la GS va in difficoltà sono le piccole ondulazioni in rapidissima successione: forse a causa della ridotta escursione della sospensione e complice probabilmente l’irrigidimento del telaio nella zona anteriore, il Telelever va in crisi sullo sconnesso a velocità comprese tra 120 e 150 km/h, e la gomma anteriore fatica a copiare il terreno restituendo qualche sbacchettata di sterzo. Colpa della moto o di chi, come noi, si lancia su terra a velocità “dakariane”?"


The key term which Google has not translated is sbacchettata. A search on the term brings up a bunch of YouTube videos whose common thread seems to be ... hmm, some sort of shaking or oscillation, possibly of the steering.

Edit: sorry, missed some stuff above while typing. Starting to look like more than coincidence.

This kind of stuff just strengthens my everlasting thoughts that the Telelever is a bad idea in a bike like the GS.
I've tried some GSs over the years, and the fork is one of the reasons why I feel my S10 better offroad.

Unfortunatelly I belive the Telelever is one of those german things made to make the GS "different", AKA design arrogance

Well it's an English thing that one manufacturer borrowed and stuck with. It has its pros and cons like everything else.

What makes you think it's a telelever issue? The telelever has been around for ages in a good part of the BMW product line without any of the issues being reported about the new GS.

Eh?

If you see some of the threads here, it has been reported that a fork brace on the regular GS aids the handling enormously! And thats with those thick stanchion tubes. And now BMW has gone ahead and made them thinner. Why do they have to resort to this kind of cost cutting? No doubt it will now need a fork brace even more. The telelever is actually a nice thing. Not about arrogance but I love the fact that I have full suspension travel even under braking under emergency situations.

sbachettata

"sbachettata" in italian means a strong shaking of the stearing, it normally accurs when accelerating, I'don't know if this is the case.
The jurnalist also says: Is it because of the bike or because of us riding on a dirt road at dakarian speed?

Thank you for the translation, igorpetrovich, and welcome to the forum.

"dakarian" - I like that!

But we can answer his question for him, for we have the other reports above, among them one from Kevin Duke of motorcycle.com who recounts some fearful sbachettata arising at the apparently un-dakarian pace of 45mph (75kmh).

There is also the Bike UK reporter, who does not give the speed at which a tankslapper broke his steering stops but who hypothesises that he may "just happen to have stumbled on exactly the wrong combination of speed and road surface at the wrong time", and that the incident therefore was a one-off.

Add it up and we can say so far ...

To Bike, no, not a one-off incident.

To Motociclismo: no, not only at arguably inappropriate speeds.

To all three: yes, it is starting to look like a bit of a problem with the bike.

And to canadamotoguide.com, whose reporter experienced something similar but opined that "It isn’t alarming": well, it has been alarming for some.

So has nobody EVER had a tankslapper whilst riding the current 12GS off road? I seem to remember a post only last week of a guy riding across the desert on a GSA and wrecking the bike.

1) I think we shouldn't overreact but we should definitely take note. I think that a few of the "reviews" are actually recycled and in reality it sums to 2-3 independent reports about the vibration-up-to-slapping issue off-road. This is still a lot though. I REALLY hope they find what it is and explain (AND RESOLVE). This bike doesn't more bad publicity. I mean for the 6 years that I own the big GS, half people tell me how great bike this is, few argue about it being air cooled (which was never a real problem) and MANY are concerned about build issues (I had none actually, except the front suspension loosing oil in an off-road session, where I managed to live with it for a week - bless telelever - with "normal" riding until the replacement came - under warranty of course). I definitely will postpone a purchase (not that I COULD make an early one anyway), until this thing clears a bit.
I am afraid the thinner forks DO have much to do with the issue. Something VERY DIFFICULT to change right now!
Quote me, I believe GS will return to previous fork diameter by the time they release the Adventure version.

2) I remember now why I was not active in the forum for years. I cannot... not notice how some very old "untouchable" members acted in relation to Kevin's death and how it relates to the bike's "fault". If this is a subject to make jokes, I don't get it. Anyway, I should have ignored this I guess like everybody else.

3) Has anybody got MCN's mag review?

Some indirect news. Here is the tire that most 2013 GS will have installed from the factory:

http://www.youtube.com/watch?v=rPU7VL55oSE

It is very on-road biased (like 90/10), but it might be of interest to some (like to me ) that within the year they will also make a new version called "Anakee Wild", already homologated for GS, that will be more off-road biased than Anakee III. Let see where this is positioned in the range, because for big GS we have many 90/10, 85/15 and 20/80 tires, but nothing closer to 60/40 (like maybe Metzeler Enduro 3) that some of us may need and is available for the dimensions of smaller GSes.
