DescriptionThe whole story▼
The Nolan X-804 RS Ultra Carbon Lesmo in Red/Grey/Gold is a full-face helmet that earns its place on both the daily commute and the circuit without asking you to choose between the two. Crafted in Italy from ultra-lightweight carbon fibre and certified to ECE 22.06, it delivers genuine race-derived protection with the all-day wearability that regular riding demands.
Key Features
- Ultra-Carbon shell in four outer sizes and six EPS inner shells for a precise, tailored fit across the full size range
- RAF (Racing Air Flow System) channels airflow efficiently, keeping you comfortable on long road stints and hard track sessions alike
- NERS (Nolan Emergency Release System) allows rapid helmet removal by first responders — a critical safety advantage in an emergency
- RAS (Racetrack Aerodynamic Spoiler) maintains stability at speed without adding unnecessary bulk
- Ultrawide, flat, scratch-resistant visor fitted with a Pinlock anti-fog insert as standard, plus a second dark track-only visor included in the box
- LAF (Liner Adjustable Fitting) and LPC (Liner Position Control) let you dial in the inner padding to match your head shape precisely
Comfort You Can Live With
A race-spec helmet only delivers its potential when you can focus on riding rather than fighting discomfort. Nolan's activated-carbon inner lining stays fresh through long sessions, and the sand-coloured breathable liner is fully removable and machine-washable. Cheek pads are available in multiple thicknesses so you can fine-tune the fit over time, and the double-D ring retention system provides secure, no-fuss closure every time you put the helmet on. The lower rear profile allows freer head movement when tucked behind a screen, and the helmet is pre-configured to accept a Camel Bag hydration system for endurance days. The Carbon Fitting Racing Experience liner concept ties everything together, giving the interior a cockpit-like feel that makes hours in the saddle genuinely manageable. Spectacle wearers will also find the X-804 RS accommodating, an uncommon courtesy in a helmet pitched firmly at the performance end of the market.
Safety and Visibility
Every structural decision in the X-804 RS starts from the ECE 22.06 certification requirement and works outward from there. The Safety Visor Lock System prevents accidental visor opening at speed — a detail that matters most precisely when you are least able to deal with the consequences. The ultrawide visor geometry maximises peripheral awareness in traffic and on track, and the included Pinlock insert eliminates fogging across a wide temperature range. The additional dark visor, also included, means you are ready for bright-light track conditions without carrying a separate bag of spares.
Lesmo Red/Grey/Gold — Design with Purpose
The Lesmo colourway takes its name from the legendary Lesmo corners of the Autodromo Nazionale Monza, and the graphic reflects that heritage without resorting to cliché. The combination of natural carbon weave, red, grey and gold creates a dynamic, layered finish that reads as purposeful rather than decorative. It is a colour scheme that looks just as credible filtering through city traffic as it does behind the pit-lane barrier.
Additional Technical Details
- Composite carbon-fibre outer shell manufactured in Italy
- Removable and adjustable aerodynamic spoiler and deflector
- Lower rear edge profile for increased freedom of movement
- Camel Bag hydration system compatible
