Nolan X-804 RS Ultra Carbon Gemini White/Blue/Red 365 Helmet

When you spend hours in the saddle — whether on a fast road loop or a full track day — the helmet that truly fits is the one you stop thinking about. The Nolan X-804 RS Ultra Carbon in Gemini White/Blue/Red 365 is engineered precisely for that sensation: a carbon fibre shell light enough to vanish from your awareness, paired with an interior system that keeps you cool, dry and locked in position from the first corner to the last.

Key Features

• Ultra-lightweight carbon fibre outer shell across four shell sizes and six EPS liner sizes for an accurate, tailored fit in every head size from XXS to XXXL
• LAF (Liner Adjustable Fitting) and LPC (Liner Position Control) let you dial in millimetre-precise positioning so the helmet sits correctly on your specific head shape
• Carbon Fitting Racing Experience interior with activated-carbon fibres that regulate temperature and moisture throughout long rides and high-speed sessions
• Removable and washable interior lining keeps the helmet feeling fresh across an entire season
• Eyewear Adaptive System accommodates glasses wearers without pressure points or seal gaps
• Camel Bag hydration system compatibility for endurance road and track use
• ECE 22.06 certified to the highest current homologation standard

All-Day Comfort Built Around You

Comfort on a full-face helmet is rarely a single feature — it is a system. Nolan has built several interlocking solutions into the X-804 RS to ensure the helmet adapts to you rather than the other way around. The LAF system allows the cheek pads and crown liner to be adjusted independently, removing the hot spots and pressure that accumulate on longer rides. The LPC system then fine-tunes the liner position so the helmet sits squarely on your head rather than rolling forward or back under braking.

The Carbon Fitting Racing Experience liner takes moisture management seriously. Activated-carbon fibres draw humidity away from the skin and regulate temperature, so even on a warm track day your focus stays on the riding rather than the discomfort. When the day is done the entire interior lifts out for a straightforward wash, returning it to the same fresh condition for the next outing.

Aerodynamics and Ventilation

The RAS (Racetrack Aerodynamic Spoiler) was developed through CFD simulation and real-circuit testing to maintain stability under the high-speed pressure changes that occur during hard braking and corner entry. At the same time the RAF (Racing Air Flow System) channels fresh air through the shell and across the liner, preventing the heat build-up that causes fatigue during sustained fast riding. The two systems work in concert: the spoiler keeps the shell planted while the ventilation keeps the rider alert.

Visor Clarity and Security

The ultrawide visor delivers a 97° vertical and 225° horizontal field of view, giving you the full peripheral picture at speed. The Safety Visor Lock System (SVLS) holds the visor positively closed at any velocity, eliminating the flutter and lift that can distract at motorway and circuit speeds. A Pinlock anti-fog insert is included in the box, and the package also includes a dedicated track-only visor and a tear-off kit for competitive use. A screw-locking system on the visor mount keeps everything secure under racing conditions.

NERS Emergency Release System

The NERS (Nolan Emergency Release System) allows first responders to remove the helmet safely and quickly in an emergency without placing stress on the rider's neck or spine. It is a feature that adds no perceptible weight or bulk to the everyday experience but represents a meaningful level of preparation for the unexpected.

Gemini 365 White/Blue/Red — the Colour That Sets the Tone

The Gemini 365 graphic brings together a dynamic white base, deep blue and an intense red accent in a design that reads as purposeful at standstill and clean at speed. The gloss carbon structure visible through the shell surface reinforces the performance intent without resorting to unnecessary decoration. It is a distinctly Italian resolution of the balance between restraint and character.

Size Guide

Measure your head circumference approximately 2 cm above the eyebrows with a soft tape. If your measurement falls between two sizes, choose the smaller — it will bed in and provide a sportier, more secure fit.

Fitment & Compatibility

The Nolan X-804 RS Ultra Carbon is a full-face helmet suitable for road and track use. It is compatible with Nolan-system Pinlock visors, the included tear-off system, and standard Camel Bag hydration reservoirs routed through the chin bar. No specific motorcycle fitment applies.
