Brembo Serie Oro Floating Front Brake Rotor 78B40813 for Suzuki DR-Z400S

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 the braking performance of your Suzuki DR-Z400S with the Brembo Serie Oro Floating Front Brake Rotor, manufacturer part number 78B40813. Designed as a direct replacement for the original equipment brake disc, this floating rotor combines a stainless steel braking band with a CNC-machined and anodized aluminum alloy hub. The result is dependable braking performance with carefully controlled construction suited to both street and demanding riding conditions.

Brembo applies its extensive brake-system engineering experience to the Serie Oro range, refining the rotor’s geometry, machining tolerances, and operating characteristics. The floating design allows the braking band to manage heat and mechanical loads effectively while helping transmit braking torque with greater consistency. These features support stable performance during repeated braking and provide resistance to thermal and mechanical stress.

This Brembo Serie Oro front rotor fits 2000–2009 Suzuki DR-Z400S motorcycles and is fully interchangeable with the original equipment front brake disc when matched to the listed application. The Serie Oro line originated from Brembo’s racing development and has become recognized for performance-oriented brake components. Expanded fitment information may be available through WPS Orders.
