Born from decades of MotoGP and Superbike development, the Nolan X-804 RS Ultra Carbon in the Lesmo Black/Grey/Gold 361 livery is a race-bred full-face helmet engineered for riders who refuse to compromise at the limit. Its exposed carbon-fibre shell, aerodynamic race systems and track-only dark visor make it equally at home on a circuit flying lap as on a demanding mountain road.

Key Features

• Ultra-Carbon composite shell in four outer sizes and six EPS liner sizes for an exceptionally precise, performance-tuned fit
• RAS (Racetrack Aerodynamic Spoiler) delivers measurable stability at high speed, suppressing lift without adding drag
• RAF (Racing Air Flow) ventilation system channels fresh air efficiently across the skull for sustained cooling on track
• NERS (Nolan Emergency Release System) allows trained marshals to remove the helmet safely after an incident
• Ultrawide flat visor with scratch-resistant coating and Pinlock inner lens included — plus a dedicated track-only dark visor in the box
• ECE 22.06 certified for road and circuit use across all available sizes

Race-Derived Construction

The X-804 RS Ultra Carbon shell is the direct result of Nolan's involvement at the highest levels of motorcycle racing. Carbon-fibre construction keeps the weight to 1420 g ±50 g while delivering the structural rigidity needed to maintain aerodynamic form at extreme velocities. Four distinct outer shell sizes and six matching EPS configurations mean the helmet scales correctly from XXS to XXXL rather than relying on padding alone to bridge the gaps — a detail that matters enormously when every gram and every millimetre of fit affects rider focus.

The removable RAS spoiler is tuned specifically for the aerodynamic profile of this shell, working with the RAF ventilation channels to keep the helmet planted and the rider's head cool. A wind deflector and breath deflector are included as standard.

Comfort at Racing Level

The Carbon Fitting Racing Experience interior uses activated-carbon fabric that stays fresh across long sessions and warm conditions. The Liner Position Control (LPC) system allows the internal liner to be repositioned with millimetre precision to suit different head shapes — a feature more commonly found on bespoke race kit than production helmets. Cheek pads are three-dimensionally shaped and available in multiple thicknesses so the fit can be dialled in without compromise.

• Antibacterial, breathable interior liner — removable and machine washable
• LAF (Liner Adjustable Fitting) system for personalised liner positioning
• Double-D ring fastening for secure, repeatable closure
• Camel-bag hydration system compatible — essential for endurance track days
• Glasses-friendly interior construction for riders who wear spectacles

Visibility and Visor Technology

At race pace every sightline is critical. The Ultrawide flat visor provides an expansive field of vision with a scratch-resistant exterior surface and a Pinlock anti-fog inner lens that keeps optics clear across changing track conditions. The Safety Visor Lock System (SVLS) prevents the visor from lifting under aerodynamic load at speed. A dedicated track-only dark visor ships in the box alongside the standard clear unit, so riders can switch configurations to suit ambient light without carrying a separate bag of spares.

• Scratch-resistant, anti-fog Pinlock visor system
• Track-only dark visor included
• Adjustable visor mechanism with safety locking screw
• Tear-off kit compatible for circuit use

Lesmo 361 — Design Rooted in Racing Heritage

The Lesmo 361 graphic draws its name and its energy from the iconic Lesmo corners at Monza — one of the fastest and most unforgiving stretches of circuit in the world. The interplay of black, grey and gold against the exposed carbon-fibre structure creates a livery that reads as authentically race-derived rather than cosmetically applied. It is a graphic identity built for performance-oriented riders who want their helmet to reflect what it is actually capable of.

Fitment and Compatibility

The Nolan X-804 RS Ultra Carbon Lesmo 361 is a universal full-face helmet homologated to ECE 22.06 and suitable for road and track use. It is not compatible with the Nolan N-Com Bluetooth intercom system. The helmet is suitable for glasses wearers.

Size Guide

Measure your head circumference approximately 2 cm above the eyebrows, keeping the tape parallel to the floor. If your measurement falls between two sizes, select the smaller — it will provide the correct sporting fit as the liner beds in.
