For the first time ever, a track‑only motorcycle features the exact same carbon‑carbon disc used in MotoGP. Not a derivative. Not a technological inspiration. The very same disc.
On the Aprilia X 250TH, produced as a limited edition, Brembo conveys a legacy forged on the racetrack: a one-of-a-kind solution, unprecedented among commercially available track-use motorcycles.
The leap no one had taken before
When the goal is to push beyond every known boundary, ordinary choices are not enough. Brembo and Aprilia know this well: every detail of the X 250TH is born from a categorical refusal to compromise. And braking, more than anything else, is where this philosophy becomes physical.
Carbon-carbon is the material of victory. For decades, it has stopped the fastest bikes in the world in the MotoGP pits, at the impossible braking points of Jerez, Mugello, Sepang. It operates at temperatures that would melt any alternative. It responds in a progressive, repeatable, absolute way.
Bringing it to a commercially available bike meant solving problems no one had tackled before. Doing it with the same disc - not an adapted version, the disc - is the difference between being inspired by MotoGP and being MotoGP.
A system designed around carbon-carbon
The disc is not a component that can be installed in an existing system. It is a gravitational center around which everything else must be designed.
The caliper, the master cylinder, the pad materials, the bell geometry: every element of the front system of the X 250TH has been developed in symbiosis with the carbon-carbon disc. The result is a system that thinks, responds, and brakes as a single entity. Just like in MotoGP.
The disc
The 340 mm carbon-carbon disc installed on the Aprilia X 250TH is identical, in materials and production process, to the one Brembo supplies to MotoGP teams. Every fiber, every layer, every surface treatment: zero differences.
The floating mounting system, directly derived from racing use, ensures the disc's free thermal expansion without transmitting stress to the fork.
The use of carbon also allows for a significant reduction in unsprung masses and optimizes the response during load variations in braking, with direct benefits on stability and feel.
A concept amplified by a setup designed to reduce unsprung masses and maximize control: Öhlins suspension and Marchesini 7-spoke magnesium wheels. Every component works in synergy, allowing the braking system to fully express its potential in terms of precision, control, and consistency at high speeds.
The caliper
The monobloc aluminum front caliper, machined from solid, is designed to ensure maximum stiffness and braking precision. The cooling fins optimize thermal management even under the most extreme usage conditions.
The four differentiated titanium pistons, measuring 34/38 mm, ensure uniform pressure distribution, improving modulation, responsiveness, and performance consistency.
The pads with carbon compound are developed to guarantee maximum efficiency within the operational thermal range of the carbon-carbon disc.
The master cylinder
In a system designed around the most extreme disc ever mounted on a production motorcycle, the brake master cylinder is not just a simple component: it is an integral part of performance.
For the Aprilia X 250TH, Brembo has developed a brake master cylinder machined from solid with a 19x20 mm interaxis, designed to ensure maximum precision, control, and consistent feel even under the most demanding conditions of use.
The rear system
Nothing is left to chance. Not even the rear system.
The standard steel disc is paired with a nickel-plated Brembo racing caliper with two 34 mm pistons (P2x34), developed to ensure consistent performance, reliability, and precision in controlling rear braking.
From today, the track holds no more secrets
Some motorcycles are ridden. Few rewrite the rules. The Aprilia X 250TH is among those that forever change the meaning of what is possible.
More than a project: a shared vision
