The coupling rotor / bell shape (no bushing) allows the transmission of the braking torque more effectively and improves the resistance to thermo-mechanical stress. The Brembo Racing T-DRIVE system allows the floatation both radial and axial, and reduces the overall weight of the disc, leading a healthy lead in driveability. The braking surface, the same steel discs used in MotoGP and SBK, It 'been optimized both by reducing the height (more lightweight mobility) and redistributing the arrangement of holes (of different diameters). The bell also contributes substantially to the final result: made of light alloy by CNC machining, and is designed for lightness and rigidity.
