Some more detailed pics would be good but they don't look like GSXR forks. The early models had anti dive mounted to the lower front, so its not them and the 1989 gsxr 1100 K had the last right side up forks, I have 2 sets of them in my garage, i'll have a look tomorrow but I don't think they are them either. Do those rims have round spokes or flat.. what size are they? One thing the 1100K forks do have is a screwdriver operated damping control on the lower part of the legs, they also have preload control on the tops of the forks..
