Developed using experience from Formula One and other elite racing categories, it combines Stilo’s ultra-light Puro Tech carbon construction with improved aerodynamics, increased airflow, greater downward visibility, and FIA 8860-2018 advanced helmet protection.\u003c\/div\u003e\n\u003cp\u003eDesigned for drivers who require maximum protection without the reduced eyeport of an ABP helmet, the ST6 FN ZERO delivers a wide field of vision, a compact four-shell sizing platform, redesigned interior padding, and an injection-molded visor secured by Stilo’s dual-position visor locking system.\u003c\/p\u003e\n\u003ch2\u003eFlagship ST6 Helmet for Formula and Open-Wheel Racing\u003c\/h2\u003e\n\u003cp\u003eThe ST6 FN configuration was developed specifically for open-wheel and open-cockpit competition. Its streamlined shell, stable interior, improved airflow, and expanded downward field of view address the conditions drivers experience in formula cars, prototypes, and other exposed-cockpit vehicles.\u003c\/p\u003e\n\u003cp\u003eThe FN interior does not rely on permanently integrated GT-style radio electronics. Instead, specially designed padding channels make it easier to route optional communication equipment, air hoses, and hydration components according to the requirements of the driver and vehicle.\u003c\/p\u003e\n\u003ch2\u003eFIA 8860-2018 Advanced Helmet Protection\u003c\/h2\u003e\n\u003cp\u003eThe Stilo ST6 FN ZERO is homologated to the FIA 8860-2018 advanced helmet standard under homologation number AH.030.24-C. This professional-level standard requires significantly higher impact, penetration, shell-strength, and flame-resistance performance than entry-level motorsport helmet certifications.\u003c\/p\u003e\n\u003cp\u003eThis model is the standard non-ABP version. It does not include the extended forehead protection and reduced eyeport found on the ST6 FN ZERO ABP. Drivers should confirm whether their championship requires standard FIA 8860-2018 or FIA 8860-2018-ABP homologation before ordering.\u003c\/p\u003e\n\u003ch2\u003ePuro Tech Carbon Fiber Construction\u003c\/h2\u003e\n\u003cp\u003eThe ST6 FN ZERO uses Stilo’s proprietary Puro Tech carbon fiber manufacturing process. Puro Tech reduces the need for heavy cosmetic lacquer and additional external coatings, allowing the natural carbon shell to remain visible while minimizing unnecessary weight.\u003c\/p\u003e\n\u003cp\u003eEach shell is produced with careful control of its carbon layers to create a lightweight, compact helmet capable of meeting the demanding performance requirements of FIA 8860-2018. The exposed carbon finish also gives every helmet the distinctive appearance associated with Stilo’s premium ZERO range.\u003c\/p\u003e\n\u003ch2\u003eFour Shell Sizes Reduce Weight and Exterior Bulk\u003c\/h2\u003e\n\u003cp\u003eThe ZERO range uses four exterior shell sizes so each interior size can be placed into the smallest appropriate helmet shell. This creates a more proportional fit and avoids surrounding smaller head sizes with unnecessary material and exterior volume.\u003c\/p\u003e\n\u003cp\u003eA smaller, lighter shell can improve cockpit clearance, aerodynamic stability, balance, and comfort. It can also reduce the strain placed on the driver’s head and neck during long sessions or repeated high-g cornering.\u003c\/p\u003e\n\u003ch2\u003eMajor Improvements Over the Stilo ST5 ZERO\u003c\/h2\u003e\n\u003cp\u003eThe ST6 platform advances the successful ST5 design with improvements focused on weight, airflow, visibility, comfort, and visor operation.

Drivers who require Advanced Ballistic Protection must select a helmet specifically labeled and homologated as the ST6 FN ZERO ABP.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat type of racing is the ST6 FN designed for?\u003c\/strong\u003e\u003cbr\u003eThe FN configuration is designed primarily for formula, open-wheel, and other open-cockpit racing applications.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the difference between the ST6 FN ZERO and the regular ST6 FN 8860?\u003c\/strong\u003e\u003cbr\u003eThe ZERO uses Stilo’s premium Puro Tech carbon construction and an additional shell size to minimize weight and exterior dimensions. The standard 8860 version uses a different carbon construction while retaining FIA 8860-2018 approval.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes the ST6 FN ZERO include radio communications?\u003c\/strong\u003e\u003cbr\u003eNo. The helmet is prepared for optional non-integrated communication equipment, but microphones, earbuds, speakers, wiring, connectors, and radio adapters are sold separately unless specifically stated.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes the ST6 FN ZERO include noise-reduction earmuffs?\u003c\/strong\u003e\u003cbr\u003eNo standard noise-attenuating earmuffs are listed for the FN configuration. Those features are more closely associated with Stilo’s GT and rally-oriented helmet interiors.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan a communication system be added later?\u003c\/strong\u003e\u003cbr\u003eYes. The interior includes routing channels intended to simplify the installation of compatible communication equipment. The correct kit depends on the radio, connector, microphone, and earbud system being used.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan the ST6 FN ZERO use a forced-air system?\u003c\/strong\u003e\u003cbr\u003eYes. Stilo offers compatible top-air and ventilation accessories for the ST6 platform. The correct component depends on helmet shell size, cockpit layout, hose diameter, and connection direction.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes the visor have an anti-fog treatment?\u003c\/strong\u003e\u003cbr\u003eYes. The injection-molded visor uses a washable high-performance anti-fog treatment. Use only suitable water-based cleaning products and soft materials.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow does the dual visor lock work?\u003c\/strong\u003e\u003cbr\u003eThe central mechanism provides a fully closed position and a separate locked ventilation position. Both positions keep the visor positively engaged.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I use an ST5 visor on the ST6 FN ZERO?\u003c\/strong\u003e\u003cbr\u003eNo. The ST6 uses a redesigned visor, pivot system, and mounting hardware. Use only shields specifically listed for the Stilo ST6.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I install an ABP visor on this helmet?\u003c\/strong\u003e\u003cbr\u003eAn ABP visor does not convert a standard helmet into an ABP-certified model. The helmet remains certified only to the homologation printed on its FIA label.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs the ST6 FN ZERO suitable for a closed-cockpit GT car?\u003c\/strong\u003e\u003cbr\u003eIt may be permitted when its certification meets the applicable rules, but drivers who need integrated communications, enhanced noise isolation, or adjustable ear padding may prefer the ST6 GT ZERO.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eShould I automatically order one size larger in Stilo?\u003c\/strong\u003e\u003cbr\u003eNo. Some drivers who wear size 59 in other brands prefer Stilo size 60, but fit varies by head shape. Measure carefully and compare the result with the current Stilo sizing chart.\u003c\/p\u003e\n\u003ch2\u003eSignature Required for Delivery\u003c\/h2\u003e\n\u003cp\u003eThis helmet ships with a signature required at delivery due to its value.
