1 K1200 front rotor on K1100 forks (size and bolt hole differences) Thu May 22, 2014 7:54 am

Hi,
AFAIK the rotor size for the K1200LT front brakes is 320mm and uses a 5 hole attachment directly to the wheel. The K1100 rotor is 305mm and uses a 6 hole attachment through a carrier to the wheel. So far, so good.
This photo shows a K1200LT wheel on a K1100 yet there is no adapter fabricated for the 4-pot Brembo calipers; they bolt directly on the fork stanchions despite the 15mm rotor diameter difference.
There isn't a lot of headroom under the caliper even with the K1100 rotors, as this picture demonstrates:
Is there some "trickery" to accomplish this?
My interest in getting an answer to this question is driven by the idea that I might perform this K12 wheel swap on my K75. There is a local seller offering a K12LT wheel at a good price. The reason is partially to get access to a selection of wider radial tires and partially esthetics.
