Constructed from a hand-laid ultra-carbon fibre shell and finished in the distinctive Blocco Grüngrau/Anthrazit/Elfenbein 370 livery, the Nolan X-804 RS Ultra Carbon is a full-face race helmet where material science and Italian craftsmanship define every millimetre. Four outer shell sizes and six EPS liner densities combine to deliver a fit precision that neither generic sizing nor heavier composite shells can match — on circuit or on road.

Key Features

• Ultra-carbon fibre shell — four shell sizes paired with six EPS densities for an accurate, performance-tuned fit across XXS to XXXL
• ECE 22.06 certified — meets the latest and most demanding European homologation standard for road and track use
• Racing Air Flow (RAF) system — wind-tunnel-developed ventilation with front chin and forehead intakes, upper channel and an aerodynamically integrated rear spoiler exhaust
• Ultrawide flat visor supplied with a Pinlock MaxVision insert and a tinted track-only visor — tear-off ready, scratch-resistant and UV-treated
• Safety Visor Lock System (SVLS) prevents inadvertent visor opening at speed; new-generation mechanism guarantees zero play at high velocity
• LAF (Liner Adjustable Fitting) and LPC (Liner Position Control) systems allow individual interior customisation, including helmet height fine-tuning unique to this class
• Manufactured in Italy with a 5-year manufacturer guarantee

Shell Construction and Safety Architecture

The X-804 RS Ultra Carbon shell is not a cosmetic carbon wrap — it is a structural carbon fibre monocoque, engineered to be simultaneously rigid and exceptionally light at approximately 1,420 g ±50 g. Multi-density EPS absorbs impact energy progressively across the full speed range, while the NERS (Nolan Emergency Release System) allows first responders to remove the cheek pads swiftly without compromising the rider's cervical spine. The result is a helmet that carries genuine racing credibility without the compromises often associated with track-only equipment.

Ventilation: Racing Air Flow System

Nolan's RAF ventilation architecture was developed in active wind-tunnel conditions rather than adapted from road-helmet tooling. High-flow front and chin intakes feed a channelled upper airstream, while the rear RAS (Racetrack Aerodynamic Spoiler) integrates the exhaust port into the aerodynamic profile rather than treating it as an afterthought. A breath deflector is included to suppress fogging during cold or wet sessions. The spoiler itself is removable for pure circuit use, simultaneously reducing drag and adjusting airflow characteristics for racing posture.

Visor Technology

The ultrawide 2D flat visor gives a panoramic, distortion-free field of view that is especially valuable at the limit, where peripheral awareness matters. It ships scratch-resistant and UV-coated as standard. The included Pinlock MaxVision insert creates a sealed anti-fog chamber, while the tinted track-only visor offers an immediate alternative for high-sun circuits. Tear-off posts are pre-fitted, and Nolan's SVLS lock mechanism ensures the visor cannot flutter or lift unexpectedly at speed. An optionally available LC photochromic visor with automatic tinting is compatible for those who move regularly between conditions.

Interior Comfort and Ergonomics

The X-804 RS interior is built around two proprietary adjustment systems that set it apart from fixed-fit race helmets. The LAF system allows the cheek pad and liner thickness to be swapped for a personalised pressure map, while LPC permits the entire liner to be repositioned vertically — a genuinely rare feature at any price point. Steady Fit 3D cheek pads use variable-density foam to cradle the face without creating pressure hot spots during long stints. The Eyewear Adaptive construction accommodates spectacle arms comfortably, and a hydration system (Camelbak-compatible) connector is built in. All interior textiles use antibacterial premium polyamide interwoven with carbon fibre strand and are fully removable and machine-washable.

Aerodynamics and High-Speed Stability

Every surface of the X-804 RS was refined through CFD (Computational Fluid Dynamics) simulation before physical wind-tunnel validation. The RAS rear spoiler generates measurable downforce on the helmet at race speeds, reducing neck fatigue in tucked riding positions and eliminating the instability that plagues lighter, aerodynamically naive shells. Its detachable design means it can be left in the pits for circuit regulations that specify a clean tail profile. Optimised neck clearance in the racing position was a specific design objective, ensuring the helmet does not foul leathers or the collar during full-lean cornering.

Fitment and Compatibility

The Nolan X-804 RS Ultra Carbon Blocco 370 is approved under ECE 22.06 for both road and track use and is available in sizes XXS through XXXL. It is not compatible with the Nolan N-Com Bluetooth intercom system. Spectacle wearers are accommodated by the Eyewear Adaptive interior architecture.

Size Guide

Measure your head circumference approximately 1 cm above the ears at the widest point to determine your correct size.
