800GS shock bolt design flaw?

I have finally lost hope in this beast. Maybe after a few days and some wrenching, my attitude will change.
To me this is going to be the Achilles heel of my 800.



I feel as though I have been realistic w/ the capabilities of this bike. The improvements I have added have made a great bike even greater. Now this.
I will be lucky to get the brackets back to their original state. I would need another bike for comparison, but it looks like the cross tube that the tabs are welded to has a bow developing.
The bottom shock bolt is also slightly bent.
Needless to say, I'm not happy right now. The design just plain sucks here. I have never seen a shock bolt so long. What were they thinking? It appears the whole shock mounting bolt was designed around providing a mounting point for the seat locking mechanism.
I'm going to straighten things out, machine some new spacers for the shock and buy new bolts top and bottom.
From here on out, I think I'd better stay on the seat and keep the speeds down.
I'm calling bullshit on BMW's advertising and claims regarding this bike (for me).

If any of you encounter bent shock bolts, please contact me. I would appreciate it.


Yes, an Ohlins shock is pictured. The stocker bent the bolts too.

Wasn't there someone here asking about a lowering kit?
Maybe I'm on to something.

Shouldn't have too.....

Hats off to ya man for being the engineer bmw should've been....Hope she works out...

I've been watching the 800, thinking about going from 1150 and a klr to something else...Couple friends are in the same boat, and they're closer than me to doing something....Both are leaning to the 800....Shit like this frickin pisses...

Couple more friends went the other way...KTM 990s...One loves it, the other has had some issues...Wouldn't be so bad if the damn things were'nt so expensive...

I first suspected something was wrong when the rear wheel was a couple of inches higher than normal when on the centerstand.
I've never had a passenger, and even when fully loaded not been over 300 +/- pounds.

Yeah, what he said.

I do own the world's largest crescent wrench. I'll have to fix things w/ that.

Math or no math, the bolt should be shorter like a regular bike.

No thread locking compound was present.

I would urge all of the 800 riders to check the bolt torque ASAP.

You bottomed that shock, hard. I'm surprised it didn't piss out all of its oil yet.

Check the body of the shock at the bottom, where the cap is pressed in. It might be mushroomed out.

I pruned the DL chatter out of this thread. Lets try to keep it on topic, eh?

Well, here we go again.

Took the bike to have the situation checked out. The dealer was horrified and said the bike would have to be bought back. Great.
I get a call a couple of days later saying my bike is ready for pick up. ???
They have installed a new top shock bolt and assure me the frame is fine. I know the frame is bending, so I go home to strip the airbox off the bike and snap a few photos.

Here is a street ridden 800 w/ probably 8-9000 miles.


Here is my frame which the dealer claimed was fine.





Looks bent to me. I decided I would go for a ride w/ a couple of ADV guys on Sunday. Hit about 90 miles of dirt I'm guessing. Nothing hard or fast.
I figured I'd give the new bolt a look. Not good. I could see the bend starting.



Now what? Back to the dealer tomorrow. This is going to be fun I'm sure.
I am preparing to just file a claim w/ my insurance company if I start getting the run around.

How are the 'Lemon Laws' in your state? Specifically, regarding multiple repairs for the same problem, without satisfaction?

Wtf?

John:

I sit here going .... holy crap thats BAD BAD BAD and unless yo are jumping off the sides of mountains there's no WAY this could be blamed on rider error.

Then I think .... how could this be the first reported failure of this type....

Then I try to figure out how it could be a problem that affects only your bike....

Then I give up....

I'm totally confused... how could you be the only guy this is happening to?

Don't get me wrong I'm not BLAMING you or anything like that ... it just seems like a problem of this type would have hit a bunch of people by now....

That is pretty much my line of thinking as well.
I'm stumped. I'll probably be forced to turn it over to my insurance.



Thinking back, I never would have known there was a problem if I hadn't bought a replacement shock. When trying to remove the top bolt on the original shock, I discovered the problem. I think the initial bent bolt is the cause of the repeat problems. I still can't imagine the cross tube bending.
I'm guessing not many 800 owners have even disassembled their bike to get a view of the top shock mount. It is a small pain in the ass.
As for rider/owner error, I am pretty good about bike prep and looking for potential problems. I have yet to even need to tighten the spokes on this bike in 8,000 miles. Aside from a couple of the shroud fasteners falling out, I have not encountered ANY loose fasteners. The bike has (at good guess) 3,000 miles of dirt on it.

The design seems poor considering the intended use of the bike. The bushing that the top shock bolt threads into just floats.


If any 800 owners have the time, I would ask if they would be willing to check this area of their bike. It will require cutting a couple of zip ties. I'm good for those!
I just can't believe (not yet) that I am all alone.
Seeing the bent cross tube is a little difficult w/ the airbox on the bike.

I checked mine, all straight. About 4500 miles of mixed use including a dualsport event loaded with camping gear and luggage. Bent front rim, but the shock bolt and frame are fine.


What kind of replacement shock do you have?

John, I'll try to check mine in the next couple of days. I have ridden hard enough to bend the front rim in several spots, and even one in the rear rim. I have bottomed it on several occasions. I'll be a good candidate to see if this is due to riding style or a particular problem with your machine....

You noticed this bolt was bent when first removing your stock shock, correct?

I'll keep you posted.
