I asked my dealer that exact question several months ago about installing Progressive springs and All-Balls bearings. I bought it from them last April. They told me they had done a few and any issues would be covered. I did not question them if it would be covered by Mother Honda OR them. I'll address it again. I have not had it done as I'm planning on riding to Woodstock this spring to have the Traxxion kit installed. As to a lawsuit, I don't think that Honda has sued RDL over seats, TBR over exhausts, or Helibars. What do you feel would be the basis for the lawsuit? Slander or libel? Probably wouldn't fly to far, IMO.
