Concern

The floating piston in the front brake master cylinder may crack

Defect, as DVSA words it

A manufacturing defect exists in a production batch of front brake master cylinder components which MV AGUSTA has installed on a series of F4 RR and F4 RC model motorcycles. The defect in the front brake master cylinder could cause it to malfunction during normal use of the motorcycle leading to a loss of front braking ability and increasing the risk of a crash. Specifically crack generation on the front brake master cylinder PPS (polyphenilene sulphide) piston connecting the internal pressure area to the external surface. The consequence is that the front brake may not participate in stopping the bike properly. The rear brake is not affected and works correctly.

Remedy, as DVSA words it

Replace the synthetic piston in the front brake master cylinder with one made from aluminium machined from solid billet guaranteeing a higher strength material as well as eliminating the possibility of porosity.
