V4S forks seem to use the same brake rotors, axle, spacers, so I'm pretty sure they'd work on a 1199S. But what are the gold circular disks on V4S forks, between the caliper mounts on the fork bottoms? 1199S/1299S forks don't seem to have those. I just want to make sure the calipers on my 1199 will mount up to the V4S fork bottoms without issue.
