Nolan X-804 RS Ultra Carbon Helmet Gemini Black/Red/Anthracite 364

The Nolan X-804 RS Ultra Carbon in Gemini Black/Red/Anthracite 364 is constructed around a full carbon fibre shell that delivers a genuinely race-derived combination of structural rigidity and minimal weight — this is a helmet where every gram of material is working as hard as the rider wearing it. Conceived on the track and refined for the road, it represents the pinnacle of Italian helmet engineering, built without concession.

Key Features

• Ultra-carbon fibre outer shell offered in four shell sizes, providing an optimally proportioned, aerodynamically precise fit across the entire size range
• NERS — Nolan Emergency Release System — allows cheek pads to be removed rapidly by first responders in an emergency without disturbing the rider's head or neck
• RAS — Racetrack Aerodynamic Spoiler — keeps the helmet planted and stable at high speeds, reducing fatigue on long straights and during sustained cornering
• RAF — Racing Air Flow ventilation system maximises through-flow under speed, channelling cool air across the head even under demanding conditions
• LAF — Liner Adjustable Fitting system allows the interior volume to be fine-tuned for a precise, custom-feeling fit without changing shell size
• ECE 22.06 certified to the most current European safety standard, suitable for both road and track use

Shell Construction and Materials

The X-804 RS Ultra Carbon begins with a carbon fibre outer shell — not a carbon-look laminate, but genuine woven carbon fibre engineered for the highest strength-to-weight ratio available in a production helmet. Four distinct outer shell sizes ensure the proportions stay correct and the EPS liner — offered in six thicknesses — fits the head properly at every point in the size range. The result is a helmet that weighs 1,420 g ±50 g across the range, achieving that figure without compromising the multi-density EPS impact management structure underneath.

Aerodynamic development was conducted using CFD simulation, with every surface — from the intake ports to the trailing spoiler — shaped to reduce drag and eliminate lift. The RAS rear spoiler is an integrated element of this aerodynamic package, not a styling detail.

Interior Comfort and Long-Distance Wearability

The Carbon Fitting Racing Experience interior lining is tailored specifically for extended, high-intensity use. Activated carbon fibres within the fabric assist with moisture management and hygiene, keeping the environment inside the helmet fresh over long sessions. The lining is fully removable and machine washable.

• Liner Position Control (LPC) allows millimetre-accurate positioning of the liner for a genuinely personalised fit
• Double-D ring fastening provides a secure, tamper-proof closure that stays locked under crash forces
• Prepared for a Camel-Bag hydration system — internal routing is already in place
• Cheek pads are available in multiple thicknesses, enabling further fit customisation independent of shell size
• Suitable for glasses wearers, with recessed channels at the temples to accommodate spectacle arms without pressure

Visor System and Visibility

The ultrawide flat visor gives an expansive, undistorted field of view at the edges — critical when tracking apexes or monitoring mirrors at speed. The Safety Visor Lock System (SVLS) holds the visor firmly sealed under aerodynamic load, preventing unwanted cracking at speed. A Pinlock anti-fog inner lens is included as standard, maintaining clarity in cold or damp conditions without the need for chemicals or breath guards.

• Ultrawide visor profile for maximum horizontal field of view
• Flat optical geometry for distortion-free vision at all angles
• Scratch-resistant coating on the outer face
• Pinlock anti-fog inner lens included
• Additional dark track-only visor included in the box
• Tear-off kit and replacement padding included

Gemini 364 Colourway

The Gemini Black/Red/Anthracite 364 graphic is built around the natural texture of the carbon fibre shell itself. Gloss carbon panels sit alongside sharp anthracite transitions and assertive red detailing — a palette that communicates performance credentials without relying on excess. The finish is as precise as the engineering beneath it, making the 364 colourway immediately identifiable whether the helmet is on a paddock stand or at 200 km/h.

Size Guide

Measure your head circumference approximately 2 cm above the eyebrows, following the largest part of the skull. If your measurement falls between two sizes, choose the smaller size for the more secure, sport-oriented fit.

Fitment & Compatibility

The Nolan X-804 RS Ultra Carbon is a universal full-face helmet and is not model- or vehicle-specific. It is not compatible with the Nolan N-Com Bluetooth intercom system. The Pinlock lens, dark visor, tear-off kit and replacement pads are all included at point of purchase — no additional visor purchase is required for track use.
