• Multi-density EPS – multi-layered impact absorption for precise impact protection

• Double-D closure – racing standard with secure fit

💡 Made in Italy: Designed, developed, and produced in Brembate di Sopra – pure Italian engineering.

Racing Air Flow – designed for peak performance

At high speeds, every detail counts.
The RAF ventilation system (Racing Air Flow) has been optimized in the wind tunnel and guarantees maximum fresh air intake and heat dissipation.

Overview of ventilation zones:

• 1 chin vent with anti-fog function

• 1 central front intake for direct air supply

• 2 upper air intakes with diffuser effect

• 2 side exhaust channels + rear outlet integrated in the spoiler

• Mesh inner cap for even air circulation

The result:
A consistently cool head – even during intense racing performance.

Visor Technology – limitless visibility & clarity

The ultra-wide visor of the X-804 RS offers an unparalleled field of view:
97° vertical and 225° horizontal – for full control in any situation.

Included equipment:

• Dark tinted visor (included)

• Pinlock® insert lens – anti-fog, adjustable from the outside

• Safety Visor Lock System (SVLS) – secures the visor at high speed

• “Track Only” visor with tear-off preparation

• Safety screw connection – stable & precisely adjustable

This way you always see clearly – whether in sun, rain, or at night.

Interior with Racing Comfort

The X-804 RS Ultra Carbon Lesmo combines ergonomics, technology, and comfort at the highest level.
With the LAF system (Liner Adjustable Fitting), you can adjust the inner lining precisely to your head shape – for optimal hold with maximum comfort.

Interior details:

• LAF system: individually adjustable padding thickness

• LPC (Liner Position Control): fine height adjustment of the lining

• 3D Steady Fit cheek pads: interchangeable & washable

• EA (Eyewear Adaptive): glasses-friendly fit

• Premium Sakura polyamide fabric: soft, robust & quick-drying

• Carbon fiber fabric: thermoregulating & antibacterial

• Camelbak preparation: perfect for long-distance racing

Result: an interior that is so precisely tuned that you hardly feel it – even at full speed.

RAS – Aerodynamics at Racing Level

The Racetrack Aerodynamic Spoiler (RAS) is the centerpiece of aerodynamic performance.
Developed through CFD simulation (Computational Fluid Dynamics), it optimizes air resistance, stability, and balance.

✅ Removable racing spoiler
✅ Reduced turbulence at top speed
✅ Improved neck freedom in racing position
✅ Perfect balance between street & track

This keeps the helmet calm and stable even at over 250 km/h – a true motorsport feature.
