Description
The Simpson SD1 is the ultimate choice for racers who refuse to compromise between weight and aerodynamic efficiency. As Simpson’s lightest helmet to date, the SD1 offers a professional-grade experience at an accessible price.
Expertly tailored for open-wheel and dirt track racing, the SD1 features a specialized design that omits front vents to keep your vision clear and your interior free of dirt and debris. The integrated front chin spoiler provides essential stability in open-cockpit environments, ensuring the helmet stays planted even at high speeds. Every SD1 is hand-built to order in New Braunfels, TX, maintaining the rigorous quality standards Simpson is known for.
Elite Protection & Standards
-
Snell SA2020 Certified: Built to the latest safety benchmarks, the SD1 is accepted by major race organizing bodies and tracks through 2030.
-
Durable Composite Shell: This model features a high-impact composite construction finished in a stealthy, non-reflective Matte Black.

Aerodynamics & Specialized Performance
-
Dirt Track Defense: The deliberate "no front vent" design is a mechanical necessity for dirt racing, preventing grit from entering the helmet. Efficient cooling is handled via dedicated top and rear exhaust vents.

Stability Enhancements: In addition to the standard front chin spoiler, an optional rear spoiler can be added for increased aerodynamic downforce and stability.
-
Forced Air Compatibility: (Coming Soon) The SD1 will offer optional top and top-left offset forced air ports for drivers requiring active cooling and advanced fog mitigation.

Safety Compliance Note
The Snell Foundation recommends replacing racing helmets 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.
