Probably won't help. It's likely the design of the wheel that allows it to clear the rear brake caliper, so you would still have to use a Carrozzeria wheel designed specifically for the VFR800 unless they are using one of their wheels designed for a Ducati.
The only other rear wheel that will clear the VFR800's OEM rear caliper/rotor is Dymag's Sport Magnesium. And you still need a modified axle (no longer available through Dymag) or axle adapter or whatnot.
Alternately, you could buy a set from Carrozzeria and try returning them after you had programmed the whole thing into autoCAD...just be prepared to make the wheels too, though.
It's already been stated(possibly in another thread), that this adapter was modeled after Triumph's setup, so one might be able to bolt up a Triumph rear. I wonder if the part # for the wheel cross-references with their Triumph wheel?
In any case, not having to pay their price for the adapter would get me that much farther ahead, eh?
I still have our discussion of the conversion saved, and while I would still like to keep the linked brakes, I would give them up to get the wheel I want. The 3 spoke rears are my least favorite, the PVM 10Y's are my #1, with the new Duc 1098 wheel a close second. Any CBR600F4 wheel with similar design can fill in the front.
I'd love to try and mill my own wheels! Trouble is getting that huge block of aluminum to start with! :beer:
ps - I have a spare 5th gen axle I'm saving to try and make the conversion with at some point, just don't know when I'll get time for it.
