Stilo AA0822AH1P54 ST6 CMR Carbon Zero Full Carbon Karting Helmet 54cm X-Small

The Stilo ST6 CMR Carbon Zero is the lightest FIA CMR-certified youth karting helmet ever produced. Built from advanced full carbon fiber using Stilo's highest-grade proprietary construction, this helmet shatters the one-kilogram barrier — the XS shell (sizes 53–56cm) weighs just 970g (2.14 lbs) — dramatically reducing neck fatigue and helping young drivers maintain sharper focus throughout every session. This listing is for the 54cm X-Small size.

Developed using technology derived directly from Stilo's Formula 1 program, the ST6 CMR Zero brings elite-level innovation to the junior karting grid. Two all-new compact shell sizes — XS and Small — reduce overall exterior dimensions by approximately 10% compared to previous models, delivering improved aerodynamics and a more precisely tailored fit for a wider range of young drivers.

Key Features:

• Ultra-Lightweight Full Carbon Construction: Weighs under 1,000g (XS shell at ~970g / 2.14 lbs) — the lightest CMR-homologated karting helmet on the market
• FIA CMR-2016 & Snell CMR Certified: Fully homologated for all youth karting competitions requiring CMR certification, designed for drivers under 15
• F1-Inspired Ventilation: Strategically engineered top ventilation ports derived from Formula 1 feedback for maximum airflow and moisture reduction during intense racing
• Expanded Downward Field of Vision: Redesigned eye-port provides significantly improved downward visibility for better track awareness and precision
• Compact Aerodynamic Shell: New XS shell (sizes 53–56cm) reduces helmet dimensions by ~10%, cutting drag and improving stability at speed
• FIA-Certified 3mm Visor: Injection-molded, double-glazed, anti-fog, and washable visor with a secure locking mechanism in both open and closed positions
• Upgraded Interior Comfort: Redesigned crown area and improved cheek padding provide a secure, comfortable fit during high-speed cornering
• Italian Engineered & Manufactured: Designed and built in Italy to exacting motorsport safety standards

The Stilo ST6 CMR Carbon Zero is the top-of-the-range model in the ST6 karting helmet family, purpose-built to give the next generation of competitive kart racers professional-grade protection, comfort, and the weight savings needed to perform at their best from the first lap to the checkered flag.
