The HD Fat Boy 1584 is a custom cruiser that embodies the rebellious spirit and massive design that made Harley-Davidson history. With its imposing weight and characteristic geometry, delivering decisive and controlled braking becomes an absolute priority for those riding this American icon on European curves and in urban traffic.
The Brembo Serie Oro Brake Discs for your Fat Boy 1584 include the front kit 78B40891 (292mm, 5mm thickness) and the rear kit 78B40828 (292mm, 5mm thickness). Both kits are designed to deliver superior braking efficiency compared to original equipment, with optimal temperature control during aggressive braking.
The main feature of the Serie Oro is the lightweight aluminium bell, which reduces unsprung weight and improves vehicle dynamics and handling. The perforated surface dissipates heat and friction gases, while pairing with premium pads ensures more linear and predictable brake response – exactly what a high-performance cruiser of this weight demands.
TÜV type approval and ABE compliance certify that these discs are road-legal throughout Europe. Installation is drop-in: direct replacement of original discs with no mechanical modifications, no brake system overhaul, and no system changes. Immediate fitment and genuine Brembo spare part, 100% Made in Italy with 2-year warranty on all components.
