All,
I'm looking for a somewhat obscure radiator part (new or used) for my K1600, though as best I can determine, the part is common to all BMW motorcycles with radiators.
In any event, it's part no 17 11 7 690 645, with a description of "Base".
In brief, this part of the radiator mounting assembly, and is a plastic spacer that prevents the rubber grommets from splitting while they carry the weight of the radiator.
If you know of someone with a scrap radiator, or any other possible source, please let me know.
Thanks,
Dominic
