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 at an accessible price point.
Tailored specifically for the rigors of open-wheel and dirt track racing, the SD1 features a specialized design with no front vents to keep your interior clear of dirt and debris. The integrated front chin spoiler provides critical stability in open-cockpit environments, keeping the helmet planted during high-speed maneuvers. Every SD1 is hand-built to order in New Braunfels, Texas, ensuring top-tier American quality and craftsmanship.

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 to ensure your equipment meets current track standards.
