Description
The Simpson SD1 is the premier choice for racers seeking a high-performance, lightweight advantage without compromising on safety. Recognized as Simpson’s lightest and most aerodynamic helmet, the SD1 offers professional-grade features and elite protection at a reasonable price.
Tailored specifically for the intense environments of open-wheel and dirt track racing, the SD1 utilizes a specialized "no front vent" design to keep your interior clear of dirt and debris. The integrated front chin spoiler provides essential stability in open-cockpit cars, ensuring the helmet remains planted during high-speed maneuvers. Every SD1 is hand-built to order in New Braunfels, Texas, maintaining a legacy of American racing excellence.
Elite Protection & Standards
-
Snell SA2020 Certified: Built to the latest safety standards, the SD1 is broadly accepted by race organizing bodies and tracks through 2030.
-
Classic White Finish: This model features a high-strength composite shell in a clean, professional White finish, perfect for maintaining a classic racing aesthetic.
-
Hand-Built Precision: Meticulously assembled in the USA to meet Simpson’s rigorous quality control benchmarks.
Aerodynamics & Specialized Performance
-
Dirt Track Optimization: The deliberate omission of front vents is a mechanical necessity for dirt racing, effectively blocking grit. Cooling is efficiently managed through dedicated top and rear exhaust vents.
-
Stability at Speed: The integrated front chin spoiler reduces lift in open-cockpit environments. For drivers seeking maximum aerodynamic balance, an optional rear spoiler is also available.
-
Forced Air Ready: (Coming Soon) The SD1 will support optional top and top-left offset forced air ports for active cooling and advanced fog mitigation.

Safety Compliance Note
The Snell Foundation recommends helmet replacement every five (5) years from the date of manufacture. Over time, the protective performance of safety liners and resins may diminish. Always verify specific safety rules with your sanctioning body before competition to ensure your equipment meets current track standards.
