Brembo Hyction Carbon Ceramic Brakes Debut on Ducati Superleggera V4 Centenario

Brembo has introduced a new Hyction carbon ceramic brake disc and GP4-HY calliper for motorcycles. This advanced braking system debuts on the Ducati Superleggera V4 Centenario. Each front disc weighs only 1.375 kg, reducing 450 grams per disc and 900 grams per wheel. The system lowers inertia by 40 percent compared to steel discs used on road superbikes.

Key Highlights

• Brembo Hyction carbon ceramic brake debuts on Ducati Superleggera V4 Centenario
• Each front disc weighs 1.375 kg and reduces inertia by 40 percent versus steel discs
• GP4-HY calliper uses differentiated pistons and anti-drag spring for improved brake response
• Ohlins NPX 25/30 Carbon fork fitted for the first time on a road bike

Key Features of the Hyction Brake System

The Hyction front disc uses carbon ceramic material, a technology derived from high-performance automotive applications. This marks the first use of such material on road motorcycles. The disc combines a carbon matrix reinforced with fibres, silicon, and silicon carbide. This construction provides high thermal resistance and structural stability. As a result, braking response remains immediate, consistent, and predictable even during prolonged use.

The disc measures 340 mm in diameter and 8 mm in thickness. It features a 35 mm braking surface and 132 ventilation holes to improve heat dissipation. The asymmetric aluminium bell and non-circular inner profile strengthen the six drive points and reduce rotating mass. Lower rotating mass and inertia help the motorcycle tip into corners more quickly, respond sharply to rider input, and maintain stability during trail braking.

GP4-HY Calliper and Rear Disc Innovations

The GP4-HY calliper is a radial monobloc machined from a single block of aluminium. Its oblique sliding pad motion generates greater brake force with the same lever pressure. Differentiated 30 mm and 34 mm pistons work with a patented system to limit residual torque and reduce pad wear. An anti-drag spring retracts the pads when the lever is released, improving responsiveness. A new organic pad compound has been developed specifically for use with carbon ceramic discs.

The rear braking system features a floating steel disc with an aluminium bell and aluminium bushings. This design, inspired by racing, reduces overall mass and enhances rear braking precision. The rear brake now offers more controlled performance and better balance with the front system.

Ohlins NPX 25/30 Carbon Fork Integration

The Ducati Superleggera V4 Centenario is also equipped with the Ohlins NPX 25/30 Carbon fork. This is the first pressurised Ohlins fork fitted to a road bike with carbon fibre outer tubes. The fork is lighter than the standard Panigale V4 version. Its pressurised cartridge reduces cavitation and maintains support during braking and corner entry.

If Brembo can extend this technology to more models, future high-performance motorcycles may benefit from more consistent braking, improved steering response, and stable lever feel under repeated heavy use.
