Upgrade the braking performance of your compatible Kawasaki motorcycle with the Brembo Serie Oro Front Floating Brake Rotor, part number 78B40840. Designed for riders seeking dependable stopping power and consistent control, this floating rotor combines Brembo engineering with carefully selected materials for reliable performance in street and spirited riding applications.
The rotor features a stainless-steel braking band connected to a CNC-machined, anodized aluminum alloy hub through drive pawls. This construction allows the braking band and hub to respond effectively to heat while helping maintain smooth, predictable braking behavior. Brembo’s precise machining tolerances support efficient transmission of braking torque and improved resistance to thermal and mechanical stress, making the rotor a durable replacement for the original front braking component.
The Serie Oro design is engineered for straightforward compatibility with select Kawasaki models, including the 2006–2010 ER-6N and the 2006–2011 EX650 Ninja 650R applications listed below. Confirm your motorcycle’s year, model, and existing brake configuration before installation. As a floating front rotor, this component is designed to help accommodate operating temperature changes while maintaining consistent contact between the brake pads and braking surface.
