Lots of upgrades can be done... to answer your question, for example:
Brembo caliper P4 30/34Brembo 15 RCS radial master cylinderThe original brake disc of the MuZ works really well with the Brembo caliper and organic or sintered brake pads (e.g. Brembo SA pads). This Grimeca brake disc on the original Grimeca rim is not easily replaced with a Brembo disc. Some Honda parts (?) fit, but I doubt if this improves brake performance.
