Brembo 1999-2002 Harley-Davidson FLHR Road King/2004-2006 FLHR Road King T-Sport Supersport Brake Disc

Brembo Supersport Brake Disc for 1999-2002 Harley-Davidson FLHR Road King & 2004-2006 FLHR Road King T-Sport

Upgrade your Harley-Davidson Road King's braking performance with the Brembo Supersport 292mm full-floating brake disc. Featuring a 5.5mm thickness for ultimate heat dissipation and anti-warping stability.

Engineered to deliver race-bred stopping power to heavy-duty touring platforms, the Brembo Supersport Brake Disc is the ultimate performance upgrade for your 1999–2002 Harley-Davidson FLHR Road King and 2004–2006 FLHR Road King T-Sport. Developed directly from Brembo’s championship-winning experience in the World SuperSport series, this high-performance rotor brings elite track technology straight to the street.

This premium two-piece assembly features a massive 34mm high braking surface crafted from thermally treated martensitic steel, designed to withstand extreme mechanical and thermal stresses without fade. The outer rotor is paired with a precision billet-aluminum alloy inner hub via a 10-fastener round-bushing drive system, providing a true full-floating configuration. By separating the outer friction ring from the central hub, the disc can expand and contract independently under high heat cycles, completely eliminating cold shrinkage and rotor warping.

Measuring a robust 292mm in diameter and an increased 5.5mm in thickness (significantly beefier than factory equipment), this disc maximizes thermal capacity to deliver exceptional, fade-free consistency. Precision engineered as a direct-fit replacement, it bolts seamlessly to your original wheel hub configuration. For aggressive riders looking to transform their Harley's frontend feel, the Brembo Supersport Series delivers an unmistakable racing aesthetic combined with absolute stopping control.

Best Uses

1. Aggressive Touring & Cruising: Perfect for riders who demand reliable, immediate stopping power when hauling heavy luggage, gear, or traveling two-up on a fully loaded Road King.
2. Mountain Pass & Canyon Riding: Ideal for traversing steep descents and winding roads where constant, heavy braking typically triggers dangerous brake fade on factory setups.
3. Performance Upgrades & Customization: Excellent choice for riders seeking a high-performance frontend transformation with a premium, race-inspired aesthetic that matches aftermarket performance styling.

Features

1. Full-Floating Two-Piece Design: Connects a rugged steel friction band to a lightweight billet-aluminum center bell via 10 heavy-duty fastener studs, allowing independent thermal expansion.
2. Martensitic Steel Braking Band: Constructed from a high-grade, thermally treated steel alloy optimized specifically to resist high operating temperatures and structural distortion.
3. 5.5mm Increased Thickness: Engineered with a thicker profile than standard OEM discs to significantly boost thermal capacity, ensuring long-term structural integrity.
4. 34mm Deep Friction Surface: Provides an expansive surface area designed for premium contact and maximum compatibility with aggressive brake pad compounds.
5. Direct OEM Replacement Bolt-on: Precision-machined to match factory Harley-Davidson wheel hub patterns for straightforward integration without complex vehicle modifications.

Benefits

1. Eliminates Brake Fade: The advanced heat capacity of the 5.5mm thick steel band ensures uniform heat distribution, preventing lever sponginess during prolonged heavy braking.
2. Prevents Rotor Warping: Full-floating floating hardware accommodates expansion at high temperatures, eradicating the common issue of lateral disc distortion and braking vibration.
3. Reduces Unsprung Weight: The billet aluminum alloy inner hub shaves critical rotating mass from the front end, improving front suspension responsiveness and handling agility.
4. Consistent Lever Feel: Delivers highly predictable, crisp, and linear braking response under both freezing initial stops and blazing hot operating conditions.
5. Track-Proven Durability: Utilizes the exact design architecture and material processing validated by elite world championship racing teams, guaranteeing unmatched longevity on the street.
