How to measure your helmet size correctly: To find the right helmet size, measure your head circumference with a flexible tape measure.
It is important that the tape measure runs around the widest part of the head – only then will you get a correct result.
Place the tape measure at the front, about 1–2 cm above the eyebrows, and run it along the sides above the ears.
At the back, the tape must run over the largest part of the back of the head (not too low on the neck). The tape may run slightly at an angle – what matters is that it sits all the way around the largest points of the head.
Make sure the tape measure sits snugly but does not dig in. Measure 2–3 times for the most accurate result. You can then compare the measured value in centimetres (cm) with our size chart.
Tips for an accurate result
- Keep hair flat (e.g. do not measure over a voluminous hairstyle)
- Keep the tape horizontal, i.e. along the largest circumference
- Do not measure too loosely
- For values between two sizes:
→ usually choose the larger size (depending on helmet model / fit)
Important note on fit
The right helmet should fit firmly without causing uncomfortable pressure points.
A new helmet may feel a little tighter at first, as the inner lining adapts slightly over time.

Born from MotoGP and Superbike podiums, the Nolan X-804 RS Ultra Carbon in Glossy Rot Liquido 326 is the flagship of the XSeries line — a race-focused full-face helmet that sets the performance bar for everything that follows it. Where the X-803 laid the foundations, the X-804 RS refines every dimension: a 100% carbon fibre shell built across four separate shell sizes, an ECE 22.06 homologation, and a starting weight of just 1,420 g (±50 g, size M) that makes its track-day intentions impossible to miss.
Key Features
- 100% carbon fibre Ultra-Carbon shell produced in four shell sizes for a precise, uncompromised fit at every head circumference
- ECE 22.06 certified — meets the latest and most stringent European homologation standard for road and race use
- RAF Racing Airflow ventilation system engineered for high-speed airflow management on track
- Ultrawide flat visor with anti-scratch coating, Pinlock inner lens included — eliminates fogging during hard riding sessions
- Prepared for tear-off strips and compatible with a camel-back hydration system for endurance sessions
- Advanced NERS (Nolan Emergency Release System) and cheek pad quick-release for fast, safe post-crash removal
- Removable and washable Carbon Fitting interior with 3D-shaped cheek pads and a glasses-friendly fit
Race-Ready Engineering
The X-804 RS Ultra Carbon is not a road helmet dressed up in race clothing — it is developed directly from the experience of Nolan's championship-winning riders in MotoGP and Superbike competition. The four-shell construction means the carbon structure is never stretched or compressed to cover an awkward size range; every size from XXS to XXXL gets a shell proportioned specifically for it. The result is optimal shell geometry, consistent protection characteristics, and weight distribution that stays neutral when you tuck behind a fairing at speed.
The Rot Liquido 326 gloss finish is a deep, vivid red that reads with clarity on track and on road alike. The aggressive silhouette — developed in the wind tunnel — reduces aerodynamic lift and buffeting even when you deviate from a full tuck, keeping your attention on the apex rather than managing helmet movement.
Visor System
The Ultrawide flat visor expands the horizontal field of vision beyond a conventional shell visor, which matters enormously when picking reference points through fast chicanes. It is scratch-resistant, prepared for tear-offs in race conditions, and ships with a Pinlock anti-fog inner lens installed. A second dark smoke visor is included for bright-light and sunny track days, allowing you to switch between clear and tinted configurations without purchasing additional accessories.
Comfort & Everyday Usability
Despite its pure racing lineage, the X-804 RS makes concessions for real-world use. The interior is fully removable and machine washable. Glasses wearers are accommodated by the shaped temple channels. The double-D-ring retention system is the gold standard for helmet security, and the chin curtain and breath guard — both included — manage turbulence and visor fogging on cold morning commutes just as effectively as they do on track mornings.
