Product description

The Nolan X-804 ST Full Face Motorcycle Helmet - Asso 342 combines Italian motorsport heritage with advanced carbon fibre construction, race-focused aerodynamics and premium rider comfort. Engineered for demanding motorcyclists, the X-804 ST Ultra Carbon offers a lightweight design, innovative safety features and an aggressive profile suited to both road and track riding.

Manufactured entirely in Italy, the Nolan X-804 ST features a lightweight carbon fibre shell engineered to balance strength, protection and high-speed performance. The removable Racetrack Aerodynamic Spoiler (RAS) contributes to the helmet's aerodynamic efficiency, while the Racing Air Flow (RAF) ventilation system promotes effective airflow during demanding riding conditions. An optimised lower rear edge profile improves neck mobility, particularly when adopting an aggressive racing position. The helmet meets the UN/ECE 22-06 safety standard.

The ultrawide, flat and scratch-resistant visor provides increased upper and lateral visibility, helping riders maintain awareness of their surroundings. A Pinlock® fog-resistant inner visor helps reduce misting in changing weather conditions, while the Safety Visor Lock System (SVLS) provides additional security. The visor mechanism also incorporates a screwed safety fixing system and adjustable positioning for enhanced functionality.

Inside, the Carbon Fitting Racing Experience comfort padding combines with the advanced Liner Adjustable Fitting (LAF) system to provide a secure, personalised fit. Anatomically shaped 3D cheek pads with removable padding and moulded polystyrene lining enhance wearability, while the Eyewear Adaptive (EA) system accommodates riders who wear glasses. The Nolan Emergency Release System (NERS), removable chin straps and D-ring retention system further enhance the helmet's rider-focused safety and comfort features.

Additional equipment includes a wind protector, breath deflector and an extra track-only visor prepared for tear-offs, supplied in the box. The helmet is also ready for a Camel Bag hydration system, with optional tear-off accessories and alternative interior padding available separately. Finished in the distinctive Asso 342 graphics, the Nolan X-804 ST Ultra Carbon combines Italian craftsmanship, advanced racing technology and striking motorsport-inspired styling.
