Developed over a decade, the Supertech R10 Miller Limited Edition Helmet is Alpinestars’ most advanced road‑racing helmet. It features a multi‑layer carbon shell with ECE 22.06, DOT and FIM certification, CFD‑ and wind‑tunnel‑honed aerodynamics, and an Optical Class 1 visor. Eleven vents and the A‑Head adjustable fit system enhance cooling and comfort, while multi‑density EPS and emergency‑release cheek pads support impact management and rapid removal.Included: 2 shields (clear and dark smoke), 2 interchangeable race and standard spoilers (Race and Road), a tear-offs set, a Pinlock lens, a wind deflector, a breath deflector, and a helmet bag.
Certification triad: ECE 22.06, DOT, and FIM homologations with impact performance exceeding standards by 37% (linear) and 65% (rotational) for proven race-level protection.
A-Head fitment system: fully adjustable height and angle to personalize comfort and maintain a locked-in feel at speed.
Patented spoiler release system: interchangeable Road and Race spoilers engineered to detach safely under load to help reduce snagging and mitigate impact forces.
Ventilation system: 11-vent layout—7 intakes (3 chin, 4 top) and 4 exhausts—for high airflow and consistent cooling.
Shield and visibility: Optical Class 1 visor with anti-fog/anti-scratch coatings, metal locking mechanism, 220° lateral/57° vertical field of view, and tool-less quick-release for rapid swaps.
Race-ready kit included: clear and dark smoke shields, Pinlock lens, tear-offs, wind and breath deflectors, plus a helmet bag for track-day convenience.
Multi-Density EPS Liner: Optimized to absorb impact forces with a low-friction coating for enhanced rotational force management.
Enhanced Chin Bar Protection: Raised profile with EPP liner to reduce collarbone injury risk.
Patented Impact Management Technology: Inner surface is polished and coated to minimize friction, allowing independent head movement to reduce transmitted rotational impact forces.
Emergency Cheek Pad Release System: Allows for easy removal by trackside medical teams.
ECE 22.06, DOT, and FIM Certified: Exceeds standard impact performance by 37% (linear) and 65% (rotational).
