Not sure they ever made any like that @EV Sportline. And the R1S has a shorter wheelbase than the R1T, so these would only work for the R1S.These are older model i thing the frames are aluminum and the tread plates that are screwed on top are steal and that’s what’s has a little rust. They fit my 2023 R1S. My understanding they fit all.
the new one are all alumimu
And welded.
