The true pleasure of riding begins where limits end. The X-904 Ultra Carbon was designed for motorcyclists 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 highway straights to the tightest mountain hairpins, this top-of-the-range full-face helmet in our XSeries line offers a precise, uncompromising solution to the real demands of the road. Elite performance meets endurance comfort: Revolutionary I-ESS visibility: Safety that demands attention. The helmet is prepared for Nolan’s advanced I-ESS (In-by-Nolan Emergency Stop Signal) system. An LED light integrated into the rear of the shell flashes automatically and intensely during sudden, hard braking, providing crucial, potentially life-saving visibility to vehicles behind in bad weather or unexpected traffic. 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. Panoramic 224° x 90° field of view: 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 safety. Fully approved in accordance with the strict ECE 22-06 regulation, the helmet features a dedicated internal housing for N-Com communication systems. The installation blends perfectly with the shell, maintaining the helmet’s clean aerodynamics and quiet acoustics. Climate management in every condition: Created to master changing climates. A high-performance ventilation system is paired with an adjustable VPS sun visor to block sudden glare. When the weather worsens, the premium visor seals and the included Pinlock® anti-fog lens ensure crystal-clear visibility.
