The radial calipers fitted to the 999R and the 1098 are 100mm, in fact I have not seen 108mm on a Ducati.
I seem to remember that Moto Wheels or was it Yoyodyne had shims for the lower triples.
I have a set of 100mm 4 pad Bembo's surplus to requirement as I just got the 1098 monoblock type.
Hmm very interesting. Most of the calipers in Motowheels European section are 108mm, but your right those bikes you mentioned are 100mm. So what are those crappy stock brembos, that your probably just gonna toss in the trash anyway, worth to you, if someone was interested in them?
