Brembo and Ducati have just pulled the wraps off the new Ducati Superleggera V4 Centenario, and buried inside all the carbon fiber and unobtanium is something way more interesting than another ultra-limited Italian flex. It’s a carbon-ceramic brake setup that finally drags hypercar tech into the world of motorcycles in a way that actually makes sense.
Let’s zero in on that front disc, because that’s the whole story.
This new Brembo Hyction carbon-ceramic rotor isn’t just some trick material swap. It’s the first time this kind of carbon-ceramic tech, the same stuff you’d find on a modern hypercar, has been properly engineered for a road bike. Not adapted or watered down, but actually reworked for two wheels. And the numbers tell you why that matters.
Each 340 mm disc weighs just 1.375 kilograms, or around 3.03 pounds. You’re saving roughly 0.99 pounds per disc compared to a steel setup, so call it nearly 2 pounds off the front wheel alone. On a car, that’s nice. On a motorcycle, that’s a seriously big deal.
Because this isn’t just weight. It’s rotating mass and inertia. Brembo claims a 40 percent drop in inertia versus a steel disc, and that’s the kind of number you don’t just feel under braking. You feel it the second you tip the bike into a corner. Brembo says that this results in sharper turn-in, which results in faster corner entry.
That’s the part people miss when they hear “carbon-ceramic brakes," because everyone thinks stopping power. But on a bike, especially something like this, it’s really about how the chassis reacts when you’re loading and unloading the front tire at speed. Less spinning mass means the bike also fights you less when you ask it to change direction. It’s subtle on paper, but massive on track.
And Brembo didn’t just stop at the material. The disc itself is packed with detail. You’re looking at 340 mm in diameter, or about 13.4 inches, with an 8 mm thickness and a 35 mm braking surface. There are 132 ventilation holes, all placed to keep heat in check when things get properly spicy. Then there’s the asymmetric aluminum carrier and a completely new inner profile that trims even more weight while keeping everything rigid under load.
It’s all tied together with a MotoGP-style floating system, so even when temperatures climb, the disc stays stable and predictable. That’s the other half of the carbon-ceramic equation. It’s not just about being light. It’s about staying consistent when you’re deep into repeated hard braking.
Of course, none of that works without a caliper that knows what it’s dealing with. That’s where the new GP4-HY comes in. It’s a radial monoblock unit carved out of a single chunk of aluminum, built specifically to work with this disc. Inside, you’ve got 30 mm and 34 mm pistons and a racing-derived boosted mechanism that gives you more braking force without needing to squeeze the lever any harder.
There’s also an anti-drag spring that pulls the pads back the instant you release the lever, which sharpens response and cuts unwanted friction. Add in a pad compound developed specifically for carbon-ceramic use, and the whole setup is tuned for feel as much as outright bite.
Even the rear setup gets the weight-obsessed treatment. A 223 mm by 4.5 mm floating steel disc with an aluminum carrier and aluminum bushings instead of steel trims even more mass. It sounds like a small detail, but on a bike like this, everything adds up.
So yeah, this is hypercar tech. But it’s not just some flashy transplant from four wheels to two. Brembo basically took the core idea, ripped it apart, and rebuilt it around what actually matters on a motorcycle. Not just brute stopping power, but how the bike behaves when you’re right at the edge.
