I was of the impression that a link is a link. Whether used on SP1 or 2 it's the same part. LDH raises doubts of how well it works on the SP2 swingarm. It was designed for the SP1 swingarm.
I have one on my SP1, put it in shortly after an Ohlins shock.
After doing a little research, I believe the Mori, Dan Kyle, and (if you can find one) RC51parts.com links are the same geometry.
I found (thanks to
) there is an HRC Link. It has completely different geometry. It was made for the Showa shock in the race ready RC51's.
The HRC link won't work with OEM shock, or Ohlins or most others without modification to spring and clevis. As I understand.
