On my old super tenere i replaced them. I think that i bought new ones from Kedo - or maybe i got a used set from somewhere else. Can't remember

But Kedo also have solid ones: http://kedo.de/produkte/40700.html

I opened mine today
Clearly visible, the one is deeper than the other one
The one on the left can't move at all, the one on the right moves free
Tried to align them and tightened again, but not happy
Hope I can get new ones, but I'm sure it can't cause any problems (hopefully not)

Aren't these suitable?

Looks like the parts needed
Thanks

Off the road.de do the bushings (I had the same issue earlier this year with the rubbers coming loose).

See photos, also meant that I could �feel� the engine more easily for vibration issues, as well as the handling benefit; buts that just my view, and everyone is different.
