The Stilo ST6 composite helmet is one of the lightest composite helmets on the market. It features enhanced airflow, visibility, and comfort while maintaining market-leading safety standards.

The brand new Stilo ST6 helmet improves on the market-leading Stilo ST5 in every way, including the following:
- 10% lighter than Stilo ST5
- 26% more airflow than Stilo ST5
- 11% more visibility

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—not 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:Â 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.

Measuring Your Head For Your New Stilo ST6 FN Composite Helmet
The most effective helmet is one that fits properly. To measure your head, have an assistant use a dressmaker’s tape or a piece of string to measure the circumference of your head. Start at a point about an inch above your eyebrows, looping around the back of your head at the point that results in the largest measurement, and finally around to the front again. It’s a good idea to take two or three measurements to make sure you have the largest one.
