New Brembo P4 30/34s @ 90 EUR Ea.

I just bought a pair myself..  Ex K1100  ..look just like Phil's pic.  Fingers crossed. Will find out in a couple of weeks.
10 mins on and I just remembered I have gsxr wheels on the way..so might have to look for adapters or sell them on..duh.
Good job they weren't expensive.

Phil, you say you have used theses BMW fitted Brembo Calipers on Ceriani's, what about the compatibility when using Marrzo's?

Not good as I understand ....... the difference is the threads in the caliper vs in the forks.

Also I have noted that there are two versions of these Brembo calipers. One with large/small pistons and one with equal sized pistons.

AH! Offset is different on both forks/calipers, Ceriani the caliper bolts inside the leg, Marzo bolts outside, but is the hole spacing the same for threaded and unthreaded P08 calipers? I would guess so, but it would necessitate a mounting plate, (which would look fugly, like fitting 30/34's) so unless I can design and make something reasonable in appearance, I might as well stick with the original P08's and squeeze a bit harder.  :D
 
Or fit Helicoils to the calipers and make some spacers up for offset.
 
But will that work fitting them to Marzo's? because on those they fit outside the mounting lug, not inside the lug as on the Cerianis.
I could use a nut and bolt through both caliper, spacer and leg if it was possible, but I think I would then need to machine the back of the lug, (inner face) flat and that might mean too little material left for safety's sake. Have you ever tried fitting them to either set of forks? 
 
Many 'Marzocchi' type F08 calipers have had Helicoils fitted and thin spacers made to fit them to Ceriani forks.
I have fitted many 4 pot Brembos to Laverdas but always with 310mm discs, so I need to use caliper adaptors.
