Brembo Serie Oro Floating discs are made from only the highest quality materials available to deliver unparalleled performance. These consist of a braking rotor in stainless steel, connected by 10 fastener screws to a CNC machined anodised aluminium alloy housing. Drawing from its immense experience, Brembo has defined the optimum geometries, tolerances and dimensions for each motorcycle type and application. As a result of specific studies into process and machining tolerances, Brembo brake discs have a unique conformation that transfers braking torque more effectively while also improving resistance to thermal and mechanical stress.  Serie Oro is the product with which Brembo entered the racing world in the mid-70s, rapidly becoming the new standard in the sector where discs are concerned.
