Brembo Serie Oro 78B40812 Floating Front Brake Rotor

Brembo Serie Oro brake discs are fully interchangeable with an Original Equipment brake disc. They consist of the stainless steel braking band connected by means of drive pawls to the hub made of CNC-machined and anodised aluminium alloy. The vast experience of Brembo was used to define the most correct geometries, tolerances and dimensions.  Resulting from a specific study of machining tolerances, the special conformation of Brembo discs allows braking torque to be transmitted more effectively while offering better resistance to thermal and mechanical stress. The Serie Oro was the range with which Brembo entered the racing world in the mid-1970s, quickly becoming the industry benchmark for discs.  Available in fixed or floating rotors.  

Upgrade braking performance and consistency with the Brembo Serie Oro 78B40812 Floating Front Brake Rotor. Designed as a fully interchangeable replacement for an Original Equipment brake disc, this rotor is engineered for riders who demand dependable stopping power, precise control, and reliable performance across demanding riding conditions. Its floating design allows the braking band and hub to work together while accommodating the stresses generated during repeated braking.

The rotor features a stainless steel braking band connected to a CNC-machined and anodized aluminum alloy hub through drive pawls. Brembo applies its extensive braking expertise to the rotor’s geometry, machining tolerances, and component interface, helping transmit braking torque efficiently while improving resistance to thermal and mechanical stress. The result is a durable front brake solution suited for replacement, restoration, or performance-focused maintenance.

As part of Brembo’s Serie Oro range, this floating front rotor reflects the technology and development experience associated with Brembo’s entry into the racing world during the mid-1970s. It is designed to deliver consistent operation while maintaining compatibility with the motorcycle’s original braking system. This front rotor fits select Suzuki RMX450Z and RM-Z250 applications from 2007 through 2015. Verify your motorcycle model, year, and existing rotor configuration before installation. Expanded fitment information may be available through WPS orders.
