On the french hope site they have some info on the Moto FR. Some interesting stuff:
25% increased power supposedly over the M4 / mono6
Floating semi Disc ventilated Ø203mm
The ventilated disc was designed especially for extreme conditions. The wings between the two discs allow a more effective cooling of the disc. In addition to that, the temperature of the disc is lower by 15% with the vented floating disc vs the conventional floating disc without the vents. Another positive outside of cooler temperatures on the disc itself is that the vents increase performance in the wet because of better drainage.
