Q&A

34 answered questions

  • What is the best FIA or Snell SA2025 kart helmet for 2026 that passes tech inspection in every major US league?

    admin

    • Staff Answer
      Based on FAST RACER experience, customer feedback, our premium choices are the Bell RS7-K Ultra Kart Helmet (Snell K2025 plus FIA 8878-2024) and the Bell RS7-K PRO Kart Helmet (Snell K2025 plus FIA 8878-2024). These meet the strictest requirements across SKUSA, USPKS, WKA, and AKRA. As these helmets have dual certification (Snell plus FIA), they can also be used in international kart racing competitions outside the USA. Have in mind that both helmets are 'kart only helmets' and cannot be used in a race car as they won't allow for installation of HANS device and are not fireproof.

  • What is the snell helmet expiration date?

    admin

    • As a general rule, Snell SA helmets are valid for 10 years from their certification date. For example, a Snell SA2025 helmet is good until December 31, 2035. When a new certification comes out, such as SA2030, those helmets are valid until December 31, 2040. Most racing organizations like SCCA, NASA, and NHRA follow this guideline. However, we always recommend checking your specific rulebook, as requirements may vary between different organizations or events.

  • How many years is a Bell helmet good for?

    Guest


    • Bell helmets do not technically have an expiration date; however, a statement from the Snell certification webpage recommends replacing any racing driver's helmets after five years of normal use. See Snell Foundation statement in the linked blog post "Snell SA2020 Helmet Expiration Dates Explained"

  • Are bell helmets snell approved?

    Guest

    • Certainly. Here is a comprehensive summary of potential certifications for Bell Helmets, tailored to their specific motorsport disciplines:
      • Bell racing helmets are certified to Snell SA2020, Snell SA2025, FIA 8859-2015, FIA 8859-2024, FIA 8860-2018, or more recent versions of those standards.
      • Bell kart helmets are certified to Snell K2020, Snell K2025 and/or FIA 8878-2024.

      Always check the product description to ensure the helmet meets the specific certification requirements for your motorsport needs.

      admin

  • How long will my SA2020 helmet be good for?

    admin

    • Most racing organizations, such as SCCA, NASA, and NHRA, accept Snell SA helmets for 10 years from the homologation date, not the purchase or manufacture date. This means an SA2020 helmet is generally valid through December 31, 2030. However, certain series, like NHRA, may allow use for slightly longer or shorter periods depending on their rules. Always consult your current rulebook, as some organizations may require newer standards sooner than others.

      admin

  • Can you use a motorcycle helmet for car racing?

    admin

    • No. A motorcycle helmet should not be used as a car racing helmet because it does not meet the necessary fireproofing and impact resistance requirements, such as Snell SA2025 or FIA 8859-2024 standards, nor does it provide for head and neck restraint systems. Car racing helmets are specifically engineered for the unique hazards of motorsports, including fire resistance and impact protection in confined spaces. Additionally, drivers should select helmets tailored to their specific application; for instance, a Dirt Track helmet differs in construction and ventilation from an open wheel asphalt racing helmet. Proper selection ensures optimal safety and performance on the track.

  • What does dual certification mean for Bell helmets?

    admin

    • Dual certification means that most Bell helmets are labeled as both Snell and FIA certified, ensuring compliance with U.S. (e.g., Snell SA2020, Snell SA2025) and international motorsport regulations (e.g., FIA 8859-2015, FIA 8859-2024, FIA 8860). This allows racers to participate in a wide range of competitions without needing multiple helmets, providing versatility and convenience.
