ZXR 400 NWS linkage

[Tadpole]

I’m enquiring about the NWS rear suspension linkage that was specifically manufactured to adjust/soften the rear suspension rebound on the Kawasaki ZXR 400 in the early/mid 90’s…
I had one on bike I had back then – and would very much like one on the current bike I now own
I was given a number for your engineering department and called them around September/October 08 and they told me they remembered these and still had 3 or 4 left on the shelf
If only I bought it then !!! Silly me
I’ve tried everywhere since but to no avail – as the bike model is now quite old and the on-line sites no longer hold them
I’m now asking the owners club to see if anyone has one of these or a contact where I can obtain these. I understand from the new owners of NWS that the old engineering department have stopped trading or retired
My question now is where did that stock go? Are they still around?
So if anyone can help could they please post a reply

Cheers
