Brembo Serie Oro Front Floating Brake Rotor 78B40844 for Kawasaki KX250F and KX450F

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 your motorcycle’s front braking performance with the Brembo Serie Oro Front Floating Brake Rotor, part number 78B40844. Designed as a fully interchangeable replacement for an Original Equipment brake disc, this rotor combines Brembo’s racing heritage with precise manufacturing and dependable performance for motocross and off-road applications. It is engineered to deliver consistent braking response while maintaining compatibility with the specified Kawasaki models.
The Serie Oro rotor features a stainless steel braking band connected to a CNC-machined and anodized aluminum alloy hub by drive pawls. This floating design allows the braking band and hub to respond effectively to heat and mechanical loads, helping improve braking torque transmission and resistance under demanding riding conditions. Brembo applies carefully developed geometries and machining tolerances to support smooth operation, reliable control, and consistent performance throughout the braking cycle.
The Serie Oro range originated from Brembo’s entry into the racing world during the mid-1970s and quickly became recognized as a benchmark for high-performance brake discs. This front floating rotor is designed for select Kawasaki KX250F and KX450F applications, including 2015–2017 KX250F models and 2006–2012 KX450F models. Confirm your motorcycle’s year and application before installation, and follow the manufacturer’s recommended procedures for fitting and bedding in the rotor.
