Brembo 78B40891 Floating Front Brake Rotor for Harley-Davidson 11.5-Inch Applications

Upgrade the front braking system on select Harley-Davidson Sportster models with the Brembo 78B40891 Floating Front Brake Rotor. Designed for dependable braking performance, this floating rotor is engineered for consistent contact between the brake pad and braking surface, helping support smooth operation during everyday riding and repeated braking conditions. Its 11.5-inch application size and 2.22-inch center bore make it a direct-fit solution for specified factory configurations.
Fits select Harley-Davidson XL883 models, including the 2009–2013 XL883N Iron 883 and the 2005–2008 and 2011 XL883L Super Low. Always verify the motorcycle model, year, original rotor specifications, and mounting configuration before installation. Proper fitment confirmation helps ensure the rotor works correctly with the existing caliper, pads, wheel, and related front brake components.
Built by Brembo, the 78B40891 combines application-specific design with the quality expected from a leading brake component manufacturer. Replacing a worn, damaged, or performance-compromised front rotor can help restore consistent braking feel and support reliable control. For best results, inspect the brake pads and mounting hardware during installation, follow the motorcycle manufacturer’s service procedures, and complete the recommended bedding process before returning the motorcycle to normal use.
