Brembo Hyction Carbon Ceramic Disc Redefines Braking for Superbikes

• Hyction carbon ceramic front disc, GP4-HY calliper on the Ducati Superleggera V4 Centenario
• Each front disc weighs just 1.375kg and cuts 450 grams per disc
• Reduces inertia by 40 percent compared with steel discs for road superbikes

Brembo has produced a new generation of braking technology for motorcycles with its new Hyction carbon ceramic brake disc, GP4-HY calliper and floating rear steel disc. This brake setup makes its debut on the Ducati Superleggera V4 Centenario combined with the Ohlins NPX 25/30 Carbon fork. It actually shines some light towards the next major shift in how braking systems are designed for high-performance two-wheelers.

Hyction front disc brings carbon ceramic material derived from extreme automotive applications for the first time to road motorcycles. It also uses carbon ceramic composite with carbon matrix reinforced by fibres integrated with silicon and silicon carbide. The result is exceptional thermal resistance and structural stability which allows the braking response to remain immediate, consistent and predictable even under prolonged stress. If Brembo’s new material keeps feel and friction more stable for longer, then braking performance will no longer be judged only by peak force, but also by how consistently that force can be delivered lap after lap or downhill corner after downhill corner.

Measures 340mm in diameter and 8mm in thickness, the disc uses a 35mm braking surface with 132 ventilation holes placed to improve heat dissipation. It also gets a newly developed asymmetric aluminium bell and a non-circular inner profile meant to strengthen the six drive points while reducing rotating mass. Rotating mass and inertia directly influence how quickly a bike tips into a corner, how sharply it responds to rider input and how planted the front end feels while trail braking. Hyction system looks towards changing brakes as stopping parts to brakes as chassis tools as well.

Each disc weighs only 1.375kg cutting 450 grams per disc and 900 grams per wheel, while also reducing inertia by 40 percent versus a steel disc for road superbikes. Less unsprung and rotating mass means the suspension has less work to do, the steering should react faster and the motorcycle can feel more precise when changing direction. This suggests that future braking systems may also help it steer better and feel lighter in dynamic use.

GP4-HY calliper has been developed to match this new disc. This calliper is a radial monobloc machined from a single block of aluminium. The oblique sliding motion of the pads generates greater brake force while asking for the same lever pressure. Inside, 30mm and 34mm differentiated pistons work with a patented system that limits residual torque and reduces pad wear. There is also an anti-drag spring that retracts the pads as soon as the rider releases the lever, sharpening responsiveness, while a new organic pad compound has been developed specifically for carbon ceramic use. This is actually a redesign of the full front-brake interaction between lever, pad, calliper and disc.

The new floating rear steel disc uses an aluminium bell and aluminium bushings rather than conventional steel bushings, a racing-derived solution intended to reduce overall mass. This offers more precise and controlled rear braking that better balances the front system’s performance. So, not just a minor support feature, but this rear braking is more integrated and better tuned across both wheels rather than focused mainly on the front discs alone.

The package includes the first pressurised Ohlins NPX 25/30 Carbon fork fitted to a road bike with carbon fibre outer tubes and reduced weight versus both the Panigale V4 R and standard Panigale V4. The fork uses a pressurised cartridge to reduce cavitation and maintain support through braking and corner entry.

If the company can scale this material and cost structure beyond a limited special machine like the Superleggera V4 Centenario, then braking on future high-performance bikes could change. They could become more consistent under heat, more influential on steering behaviour because of lower inertia, and more confidence-inspiring because lever feel and response remain more stable under repeated heavy use.
