The fixed Serie Oro brake discs are made from a single piece of stainless steel in one piece with a design and construction line that respects the very strict tolerances set with machining cycles that guarantee maximum surface flatness and concentricity characteristics. 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.
