Brembo Serie Oro Floating Front Brake Rotor 78B40848 for Yamaha WR250R

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 front braking performance of your motorcycle with the Brembo Serie Oro Floating Front Brake Rotor, manufacturer part number 78B40848. Designed as a direct replacement for the original equipment brake disc, this high-quality rotor combines Brembo engineering with proven materials and construction for reliable performance on the road or trail.

The Serie Oro rotor uses a stainless steel braking band connected by drive pawls to a CNC-machined and anodized aluminum alloy hub. This floating design allows the braking components to manage thermal expansion effectively while helping transmit braking torque more efficiently. Carefully developed machining tolerances and rotor geometry provide dependable resistance to thermal and mechanical stress during demanding riding conditions.

As part of the Brembo Serie Oro family, this front rotor reflects the brand’s long experience in racing-derived brake technology. It is engineered to fit the front braking system of 2008–2017 Yamaha WR250R models and is fully interchangeable with the original equipment brake disc. Verify your motorcycle’s application before installation, and follow the vehicle manufacturer’s service procedures for fitment and installation.
