Well, not exactly that. That's a bunch of stainless steel M8 countersunk screws stuck into the RHS of the rear brake disc/rotor--pre-machining of any sort. The point being, they're nearly flush and could be made flush with a rather minor chamfering of the axle holes. Could probably do it on the bike with a hand drill and countersink bit. There is enough clearance on the other side for a locking flange nut. (Apologies for the filthy bike!)
However, the LHS of the brake disc is recessed (like the axle flange), and while I don't think the locking flange nuts are in danger of sinking into the recess, I think I would prefer to flip the rotor around so that the surface bearing the nut is not recessed. That's an axle-out job, but should be straightforward.
An even better solution would be to use a bolt that fits into the axle's recess and thus does not require any machining at all (or maybe a slight enlargement of the holes). Something like...
These are titanium BMW S1000R front disc bolts, M8 x 26, 2mm head thickness and 3mm shoulder. I cannot tell the diameter of the shoulder, but even if it is 10mm, that should be easy to do on a drill press (although I have heard that the VFR axle is made from some really hard steel). They are also too long, but...they can be cut down.
Why? I want to be able to swap rear wheels among my VFRs and don't want to hack up my VFR800 rear wheel. I would be hacking up my FP's axle, but that doesn't seem to bother me as much!

Why can't I do this?
