I've been browsing the online K75 fiches for stuff I may need during my project but can't find any reference to it in any of the diagrams. Sort of strange because usually if a part is no longer available it will still be on the fiche but be marked NA in the "Price" column. It's like it never existed OR I'm somehow missing it. A google search doesn't turn up much either.

Can anyone shed any light on this?

There is the Damper ring still available

Also the correct silicon grease on ebay

Thanks very much. I spoke too soon and later found the part under 'Forks'. Will order the grease on eBay.
