The true pleasure of riding begins where the limits end. The X-904 Ultra Carbon was designed for riders who refuse to compromise between the pure high-speed protection of a racing helmet and the optimal long-distance comfort of a premium touring model. From endless motorway straights to the tightest mountain hairpins, this top-of-the-line full-face helmet from our XSeries range offers a precise, uncompromising solution to the real demands of the road. Elite performance meets endurance comfort: Exceptionally lightweight Ultra Carbon shell: Using a high-carbon-fiber weave, the X-904 UC delivers maximum impact resistance with minimum weight. This incredible balance drastically reduces head inertia and neck fatigue, ensuring optimal aerodynamic stability even at high speeds. Carbon X-Series interior: Much more than simple padding. The inner liner features active carbon fibers that naturally regulate temperature, control static electricity, and promote breathability. Fully adjustable and anatomically shaped, it creates a custom fit that completely eliminates pressure points on long-distance journeys. Panoramic 224° x 90° field of vision: True active safety through vision. The wide opening provides an extended panoramic view, allowing you to check the instruments at a glance and monitor obstacles in your peripheral vision without unnecessary head movements. Seamless N-Com (Sena) integration: Connect with complete peace of mind. Fully approved under the strict ECE 22-06 regulations, the helmet is equipped with a dedicated internal housing for N-Com communication systems. The installation blends perfectly into the shell, maintaining the helmet’s clean aerodynamics and quiet acoustics. Climate management in every condition: Created to master changing weather. A high-performance ventilation system is paired with an adjustable VPS sun shield to block sudden glare. When the weather deteriorates, the premium visor seals and included Pinlock® anti-fog lens ensure crystal-clear visibility. Challenge the distance. The X-904 Ultra Carbon brings racetrack engineering, absolute refinement, and iconic Italian craftsmanship to the world of modern sport touring.
