The front MC floating brake discs from the ultralight EBC Brakes X series have become one of the lightest and best-performing discs in the world since their introduction and are available for all modern sports motorcycles. The MC floating brake discs feature EBC Brakes’ exclusive and patented S-Drive rivet system, which includes square-sided rivets that allow for thermal expansion of the braking track, enabling it to expand and contract freely during braking without the rivets seizing.
