This is how to measure your helmet size correctly: To find the right helmet size, measure your head circumference with a flexible measuring tape.
It is important that the measuring tape runs at the widest part of the head – only then will you get an accurate result.
Place the measuring tape about 1–2 cm above your eyebrows at the front and run it along the sides above your ears.
At the back, the measuring tape should run over the largest point at the back of the head (not too low in the neck). The tape can run slightly diagonally – what matters is that it fits snugly around the largest circumference points of the head.
Make sure the measuring tape fits snugly but does not pinch. It’s best to measure 2–3 times to achieve the most accurate result. You can then compare the measured value in centimeters (cm) with our size chart.
Tips for an accurate result
- Lay hair flat (e.g., do not measure with a voluminous hairstyle)
- Run the measuring tape horizontally or 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 for fit
The right helmet should fit snugly without causing uncomfortable pressure points.
A new helmet may feel a bit tighter at first, as the inner padding will adjust slightly over time.

🇮🇹 Designed, developed, and produced in Italy.
Carbon Fiber Dominance – lightweight, strong, uncompromising
The outer shell of the X-804 RS Ultra Carbon is made entirely of high-strength carbon fiber, providing an unparalleled combination of stability and lightness.
With four shell sizes and six EPS inner shells, the perfect balance of safety and fit is achieved for every head size.
✅ Ultra Carbon shell – maximum strength at minimal weight
✅ ECE 22.06 certified – latest European safety standard
✅ Multi-density EPS – impact-absorbing under all conditions
✅ NERS system – emergency release for quick, safe removal
✅ Double D-ring closure – proven racing technology for absolute safety
Weighing only about 1420 g ± 50 g, this helmet is a true lightweight among racing helmets.
Racing Air Flow (RAF) – developed in the wind tunnel, proven on the track
The RAF ventilation system has been specifically designed for extreme racing conditions.
It combines several precisely placed inlets and outlets that direct airflow strategically – for a cool head even during hot lap times.
✔️ 1 chin air inlet with anti-fog function
✔️ 1 central front inlet for fresh air supply
✔️ 2 upper air inlets with diffuser function
✔️ 2 side outlets & rear spoiler exhaust system
✔️ Open mesh inner cap for even air distribution
The result: controlled ventilation, reduced turbulence, and a pleasantly dry helmet climate.
Visor technology – clear vision at any speed
The X-804 RS is equipped with an ultra-wide visor that offers a field of view of 97° vertically and 225° horizontally – for maximum control in every riding situation.
Included in the delivery:
✅ Silver-coated visor
✅ Pinlock® insert lens (anti-fog)
✅ “Track Only” visor with tear-off preparation
Innovative systems ensure stability and protection:
-
SVLS (Safety Visor Lock System) – prevents unwanted opening at high speeds
-
Visor mechanism with safety screws
-
Pinlock adjustment system – regulates tension from the outside
The result: perfect visibility, even in rain, fog, or bright sunlight.
Comfort & Interior – High-tech meets ergonomics
Nolan's X-804 RS Ultra Carbon features an interior that redefines racing comfort:

-
Premium Sakura polyamide fabric – soft, durable & quick-drying
-
Preparation for Camelbag drinking system
This ensures the helmet fits perfectly – even on long racetracks or tours.
Aerodynamics – Racing performance in its purest form
The RAS (Racetrack Aerodynamic Spoiler) was developed using state-of-the-art CFD simulation (Computational Fluid Dynamics) to minimize air resistance and lift.
The result: measurable stability and perfect balance – even at top speed.
✅ Removable racing spoiler (RAS)
✅ Optimized rear profile for free neck movement
✅ Enhanced airflow for reduced vibrations
This helmet remains stable, calm, and precise even at high speeds – a crucial advantage in racing.
