True. Unfortunately John does not have that part documented photographically. I were a dealer, I might be inclined to be skeptical.

I'm working on mileage and dates. I have quite a few bent bolts. I believe the dealer has the original. This photo isn't very easy to interpret. Viewing the stock shock in person shows much more.
I will admit to not categorically documenting things the way I should have. Hell, this thing started out as just another motorcycle for me.

I know exactly what you mean. I am beginning to have some doubts developing as well. I am in denial at the moment. BTW, I talked to two dealers today, and neither one is giving me warranty coverage on the grenaded wheel bearing. At this point I just want to bring my bike home so I am not arguing.

Yes, Frank. It did. The top one and the bottom one.

I think the shock mount not being torqued adequately from the factory is a distinct possibility. Thats based on enough reported cases of improper torque values being applied to rear sprockets, clutches and steering head bearings. I am not an engineer so I will reserve judgement on the strength of the design, though intuitively I still have trouble with two bushings butted together at 74ft# will adequately prevent the bolt from bending. How much that supported bolt load is spread over both mounts is also open to question. One look at the mounting flanges makes it obvious which one is expected to receive the most load. I am sure BMW studied how much the "lever" effect of the left mounting flange will multiply the amount of force being applied to the crossmember, at least I hope so.

Of course! The same dept who studied how to design the BMW final drive

I couldn't source a replacement Ohlins or a factory shock down there. I had to have my factory shock shipped down to me so that i could proceed with my ride.

Since i couldn't locate a new upper bolt quickly enough, we straightened the one i had. We put it all back together with the Sachs shock and straightened upper bolt, rode it like that for approximately 3,000 miles without incident.

The straightened bolt did not deform again until it was replaced by a new one upon my return home.

Since then it's been ridden another 4,000 miles, including several dual sport rides, without incident. I last checked both bolts about a week ago, with a dial indicator and V block.

Hope this is not taken as a rude question, but John & Bruno, how much do you guys weigh? And what weight of luggage would be typical?

With tools, water, extra fuel, etc. and my petite ass I'm @ 240-260 pounds combined.
Loaded for a longer trip and panniers full of clothes and beer the bike weighed in @ 560 pounds. That isn't typical for me, and I sure as hell wouldn't be tearing it up w/ that kind of weight in the dirt.

I weigh 190.

Weight had little to do with my particular failure, i hit a pretty substantial G-out at speed which caused my shock to bottom. Ohlins replaced my shock saying that they had "determined the cause of the failure".

The replacement shock was built with a higher rate spring.

I thought that Ohlins handled the situation very well. They could very easily have refused to warranty my shock based on the fact that they cannot build a product that will withstand any and all possible loads.

I'm not sure whether my Ohlins shock that failed was built with a correct rate spring, maybe it was, maybe not. I did provide all of the pertinent information required (weight, etc.) when i ordered it.

Let's say, arguendo, that my shock was built with a lower than adequate rate spring. I'm not sure that even a higher rate spring would have prevented the failure. It most likely would have helped, but who knows whether or not it would have prevented it.

When your bolt bent, did the mounts bend too?
