Stilo ST6 FN ABP 8859-2024 Carbon Fiber Helmet SA2025

Advanced ABP protection with Snell SA2025 performance

For over 25 years Stilo has led helmet innovation, and the ST6 FN ABP marks a new benchmark. With development input from top programs, the ST6 refines front and top aero for stability, broadens airflow, and expands visibility so you can focus on driving.

Built from carbon fiber for a light, rigid shell, the ST6 FN ABP blends comfort and cooling with modern safety. From the dual-lock visor system to the revised eyeport and venting, every detail is aimed at confidence and consistency on track.

The ST6 improves on the market-leading ST5 in key areas:

• 10% lighter than Stilo ST5
• 26% more airflow than Stilo ST5
• 11% more visibility
• More comfortable liner and cheek pads
• More shell sizes for lower weight
• Improved visor construction for durability and ease of care
• Higher quality visor hardware for increased reliability

What's Changing in SA2025 Auto Racing Helmets?

SA2025 helmets are here, and while the changes may not be groundbreaking, they represent an important evolution in motorsport safety. According to the Snell Memorial Foundation, the SA2025 standard is an evolutionary update from SA2020‚Äînot a complete overhaul. Unlike the M2025 motorcycle standard, which adds rotational impact testing, the SA2025 auto racing helmet standard does not include rotational force requirements.

Key SA2025 Helmet Safety Enhancements:

• Increased Impact Protection: SA2025 helmets are required to handle slightly higher impact speeds and achieve lower maximum peak G-force thresholds across all head-form sizes.
• Global FIA Alignment: These updated requirements bring the SA2025 standard into alignment with the new FIA 8859-2024 helmet safety regulation, creating more consistency across international motorsports.

In short: SA2025 helmets are designed to offer enhanced linear impact protection, making them the safest Snell-rated auto racing helmets to date. Whether you're a competitive racer or a weekend track day enthusiast, upgrading to an SA2025-certified helmet ensures compliance with future racing regulations and gives you peace of mind at speed.

Stilo ST6 FN ABP 8859-2024 / SA2025 Helmet FAQs:

Is this helmet Snell SA2025 certified? Yes, this helmet has both SA2025 certification and FIA 8859-2024 ABP homologation.

What does ABP mean? ABP indicates additional frontal protection meeting the FIA's Advanced Ballistic Protection requirement.

What's the difference between Stilo's FN and GT helmets? 

The ST6 GT is designed for closed-cockpit cars (and is often marketed for that “GT” style car environment). It features molded-in side ports for forced air, comms, and/or hydration kits integrated into the helmet shell itself.

The ST6 FN is optimized for open-cockpit, formula / sprint / open-wheel style cars. It has an aerodynamic advantage because it does not feature the side ports present on the GT model.

Can I use ST5 shields on the ST6? No. The ST6 uses its own shield family; choose ST6-specific shields and hardware.
