Good luck with this and good for you for that kind of stand up character.

"My guess is not worth that much since I have not had my own hands and eyes on your bike but for the little it is worth, I think that a part was defective or the mount bolt was left too loose and one or more parts of the frame bent and or the spacers were deformed. Once this happened no amount of replacing the bolt will do any good because quite honestly the bolt is not there to resist flexing, it is there to apply tension and the spacers and frame carry all of the sheer and flex load."


I think this sums it up.

I'm with John on the weak mount design theory. I'm no engineer, so i'm far from having any hard data to confirm my suspicion, but the span just looks too great to offer enough strength to the mount.

I also opine that the split (wimpy) bushing in the Ohlins shock exacerbates the tendency for the bolt to bend. If the bushing were stronger, it would aid in keeping the bolt from flexing.

EDIT - It would be interesting to me if someone could do some stress analysis on that bolt/mount. How much force does it take to bend the bolt and ears in the mounting configuration of the 800 GS ? Is it an acceptable figure ?

I recommend you speak with Matt Sage directly, at Ohlins USA.

Do you have any photos of the top shock area of your aftermarket shock?
I'm interested in something Bruno T mentioned about the Ohlins spacer/bushings.

John,
This is the HyperPro shock. Does this shed any light for you ?

Is there a heim joint or some sort of swivel bushing on the shock mounts?
I'll post a couple of photos of the Ohlins setup later.
