The Brembo Serie Oro Floating Front Brake Rotor, manufacturer part number 78B408A7 and vendor part number 177-0051, is designed to deliver consistent braking performance for select KTM 990 Supermoto motorcycles. This front rotor uses a stainless-steel braking band connected by drive pawls to a CNC-machined and anodized aluminum-alloy hub, combining dependable braking control with a lightweight, performance-oriented construction.
Brembo developed the rotor’s specific machining tolerances and component design to transmit braking torque effectively while improving resistance to thermal and mechanical stress. The floating rotor configuration allows the braking band and hub to respond independently as temperatures change, helping maintain stable braking behavior during demanding street or sport riding. As part of the Brembo Serie Oro line, this rotor is suited for riders seeking reliable replacement performance and precise fitment.
Fitment: Fits 2008-2011 KTM 990 Supermoto R models and 2010-2013 KTM 990 Supermoto T models. Verify the motorcycle model year and front brake configuration before installation. Professional installation is recommended, and all brake components should be inspected and properly serviced to ensure safe operation.
