Schuberth SF4 8860-2018 Carbon Fiber Helmet (Non-ABP)
The Schuberth SF4 8860-2018 Carbon Fiber Helmet brings Formula-level materials, protection, and visor technology to professional GT, prototype, endurance, and open-cockpit drivers who do not require an ABP-homologated helmet.
Handcrafted at Schuberth’s motorsport production facility in Italy, the SF4 combines an autoclave-cured carbon fiber shell with advanced ventilation, a Formula-derived injected visor, a two-stage visor lock, and extensive accessory compatibility. Its compact construction and refined interior are designed to support drivers through long race stints without compromising the advanced protection required by the FIA 8860-2018 standard.
FIA 8860-2018 Advanced Helmet Protection
The Schuberth SF4 is homologated to the FIA 8860-2018 advanced helmet standard under FIA homologation number AH.020.21-C. This is a professional-level motorsport helmet standard developed for demanding international competition.
This specific SF4 is the non-ABP version. It does not incorporate the reduced eyeport and extended upper visor-area protection found on the SF4 ABP. That distinction makes the standard SF4 particularly well suited to GT cars, prototypes, endurance vehicles, and open-cockpit applications in which the governing series does not require Advanced Ballistic Protection homologation.
Drivers should always verify the required helmet certification with their sanctioning body, race series, or event organizer before purchasing.
Handcrafted Autoclave-Cured Carbon Fiber Shell
Each Schuberth SF4 begins with a lightweight, hand-laid carbon fiber shell that is cured inside an autoclave. This specialized manufacturing process uses controlled heat and pressure to consolidate the carbon layers and create a strong, consistent helmet structure.
The shell is handcrafted at Schuberth’s dedicated motorsport facility in Italy using production techniques developed through more than two decades of Formula racing experience. The result is a compact carbon helmet that balances structural strength, low weight, aerodynamic efficiency, and Schuberth’s unmistakable motorsport profile.
Built for Long GT and Prototype Racing Stints
The SF4 was developed for drivers who may remain helmeted for extended periods during endurance, GT, and prototype competition. Its compact shell profile, balanced construction, comfortable interior, and controlled airflow help reduce distractions during long sessions.
The interior is shaped to maintain stable contact around the driver’s head and face without relying on excessive pressure. Multiple shell and interior configurations help Schuberth provide a more proportional fit across the helmet’s available size range.
Because head shape and padding preference can affect fit, drivers should use the Schuberth sizing chart as a starting point and try the helmet on whenever possible.
Formula-Derived Ventilation System
Air channels integrated into the helmet’s EPS liner distribute fresh air through the interior while directing warm air away from the driver’s head. Schuberth states that, in unrestricted airflow, the system can provide up to 14 liters of fresh air per second at 100 km/h.
The SF4 can be configured with optional ventilation accessories to suit different cockpit designs and airflow conditions. Available configurations may include individual ventilation scoops, top-air systems, chin ventilation components, and aerodynamic accessories.
This flexibility allows the helmet to be adapted for enclosed GT cockpits, forced-air systems, prototypes, and open-cockpit vehicles.
Injected Visor with Optical Clarity
The Schuberth SF4 uses an injected visor developed from the brand’s Formula racing program. The manufacturing process is designed to minimize the optical distortion that can occur through the curved viewing area of a conventional racing shield.
Schuberth offers multiple compatible visor options ranging from clear and dark tint to mirrored and multi-layer mirrored finishes. This allows drivers to select a visor suited to daytime, nighttime, bright-sun, or changing-weather competition.
Standard SF4 visors are supplied with tear-off posts, allowing compatible tear-offs to be installed for events where dirt, rubber, oil, or debris may collect on the visor surface.
Pinlock 120 Anti-Fog Performance
Standard Schuberth SF4 visors are equipped with a Pinlock 120 anti-fog lens. The insert creates an insulating air pocket between the visor and the lens, helping reduce condensation when cockpit temperature, humidity, or weather conditions change.
This system is especially valuable during endurance racing, wet events, cool-weather competition, and driver changes where moisture can quickly affect visibility.
The Pinlock lens and visor should be cleaned only with appropriate materials and techniques to avoid damaging their optical or anti-fog surfaces.
Central Two-Stage Visor Lock
The SF4’s central visor mechanism is designed to close the visor evenly on both sides of the helmet. This symmetrical closure helps create consistent engagement with the eyeport seal and provides dependable visor operation while the driver is wearing racing gloves.
The lock provides two functional positions:
-
Stage One: Keeps the visor securely locked while allowing a small amount of ventilation into the helmet.
-
Stage Two: Pulls the visor into a firmer seal to help block fine dust and water.
The ventilation position allows the driver to increase airflow without leaving the visor unsecured. The fully sealed position is intended for conditions where dust, spray, or moisture protection takes priority.
Communication-System Ready
The Schuberth SF4 can be configured with optional integrated communication electronics. This allows the driver to build a professional radio setup suited to the team’s amplifier, connector, microphone, and audio requirements.
Communication equipment is not included with the standard helmet unless it is specifically selected as part of the purchased configuration. Microphones, speakers, earphones, connectors, wiring, and related electronics may be sold separately.
Any communication or earcup configuration must comply with the rules of the driver’s sanctioning body and race series.
Customizable Aerodynamics and Airflow
Different cars create different airflow patterns around the driver’s helmet. The SF4 platform can be adapted with compatible accessories to improve airflow, aerodynamic stability, cooling, and cockpit integration.
Depending on the selected configuration, compatible Schuberth SF4 accessories may include:
- Top-air ventilation components
- Individual helmet ventilation scoops
- Chin ventilation scoops
- Rear and top aerodynamic spoilers
- Replacement clear, tinted, and mirrored visors
- Pinlock 120 anti-fog components
- Visor tear-offs
- Optional integrated communication electronics
- Replacement interior padding and fit components
Accessory availability and compatibility can vary by helmet size, production version, and intended application.
Non-ABP SF4 Versus the SF4 ABP
The standard SF4 and SF4 ABP share Schuberth’s Formula-derived carbon construction and professional motorsport engineering, but they carry different FIA homologations.
The non-ABP SF4 has a larger conventional eyeport and is intended for applications where FIA 8860-2018 certification is required but ABP homologation is not mandatory. The SF4 ABP uses an extended upper visor-area structure and reduced eyeport designed to satisfy Advanced Ballistic Protection requirements.
An accessory visor strip or reinforcement panel does not convert the standard SF4 into an ABP-homologated helmet. The helmet remains certified only to the homologation stated on its FIA label.

How to Measure for a Schuberth SF4 Helmet
Use a soft measuring tape to measure around the widest circumference of your head. Position the tape approximately one inch above your eyebrows, pass it above the ears, and wrap it around the widest point at the back of your head.
Keep the tape level and comfortably snug without pulling it tight. Take the measurement two or three times and use the largest result when reviewing the Schuberth SF4 sizing chart.
A properly fitted racing helmet should create firm, even contact around the crown, sides, and cheeks. It should not create sharp or painful pressure points, and it should not rotate independently when the chin strap is properly secured.
