Brembo Serie Oro Front Floating Brake Rotor 78B40838 for Honda CBR300R and CB300F

Upgrade the front braking system of your compatible Honda motorcycle with the Brembo Serie Oro Front Floating Brake Rotor, part number 78B40838. Designed for dependable street performance, this floating rotor combines Brembo engineering with carefully selected materials to help deliver consistent braking response, effective heat management, and reliable performance during everyday riding.

The rotor uses a stainless-steel braking band connected to a CNC-machined and anodized aluminum alloy hub by drive pawls. This construction allows the braking band and hub to work effectively as operating temperatures change, helping the rotor manage thermal expansion while maintaining smooth, predictable braking behavior. The stainless-steel braking surface is engineered to withstand regular mechanical and thermal stress, making it a practical replacement or performance-focused upgrade for compatible Honda applications.

Brembo develops the Serie Oro range using precise machining and carefully controlled tolerances. The special rotor design helps transmit braking torque more efficiently from the brake pads to the wheel, supporting confident control through traffic, corners, and repeated braking conditions. This front floating configuration is intended for riders who want Brembo quality, responsive braking feel, and a well-engineered replacement component. It fits select 2015–2018 Honda CBR300R, CBR300RA ABS, CB300F, and CB300FA ABS models; verify the motorcycle year and model before ordering.
