The Sportster 883 Custom embodies the pure essence of American cruiser styling: a machine that conveys character through every curve, with a low and controlled riding position. After years of intensive use, original discs begin to show wear and braking loses the progressivity that defines the best moments in the saddle. This is where Brembo quality steps in—the brand that has powered two-wheel legends.
The front kit 78B40891 features a 292mm disc with 5mm thickness, engineered to absorb heat generated by continuous city traffic braking and winding roads. The rear kit 78B40828 maintains identical dimensions, ensuring perfect braking balance between front and rear wheels. Both discs are crafted with aluminium bell technology, which significantly reduces unsprung weight and improves suspension responsiveness.
Peripheral drilling is the hallmark of the Serie Oro: it enables rapid evacuation of heat and residual gases produced by friction with brake pads, maintaining stable operating temperature even on long descents. The improved pad-to-disc contact translates into more precise brake modulation and a noticeable reduction in stopping distance—critical on a cruiser like the Sportster.
These discs are TÜV type approved and represent direct replacement for original Harley-Davidson components: no modifications to the brake system, no authorized workshop overhaul, drop-in installation requiring only basic skills. They are certified for street use throughout Europe and backed by a complete two-year warranty for intensive use.
