The 02 supersport would have an edge skid. The 133 has me questioning it though. I don't think they offered one for those. Is this an extension kit on the rails?
Also, I know a guy that mounted an edge skid in his xcr and he claims it made a world of difference in the ride. Iirc he has to run the tensioners all the way forward, like the skid should have been forward just a little more in the tunnel.
