Alpinestars Supertech R10 Miller LE Motorcycle Helmet

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.

Key features

• Carbon Shell Construction: Multi-layer 3K high-density carbon and uni-directional carbon reinforced with aramid fiber and fiberglass disperses impact energy and resists penetration at racing speeds.
• Tri-Standard Certification: ECE 22.06, DOT, and FIM homologation with verified performance exceeding standard requirements by up to 37% (linear) and 65% (rotational) for greater protection confidence.
• A-Head Fitment System: Height and angle adjustability lets you fine-tune helmet position for a locked-in, personalized fit.
• Aerodynamic Package: CFD-, wind-tunnel-, and track-validated profile reduces drag and lift for high-speed stability; includes Road and Race spoilers with a patented breakaway release for safety and tuning.
• 11-Port Ventilation System: Seven intakes (three chin, four crown) and four exhausts drive powerful airflow to keep you cool and focused.
• Optical Class 1 Shield System: Anti-fog/anti-scratch visor with metal locking tab and a 220degrees lateral/57degrees vertical field of view maximizes clarity; quick-release, tool-less changes speed up swaps.
• EPS Architecture: Eight-piece EPS layout with targeted zones contours to the head for a more secure, balanced fit across sizes.

Protection

• Multi-Density EPS liner: Optimized to absorb impact forces with a low-friction inner coating to enhance rotational force mitigation.
• Enhanced chin bar protection: Raised profile with EPP liner to reduce collarbone injury risk.
• Patented impact management technology: Polished, low-friction inner surface allows controlled, independent head movement to reduce transmitted rotational impact forces.
• Emergency Cheek Pad Release System: Enables safe helmet removal by trackside medical personnel.
• Certified protection: ECE 22.06, DOT, and FIM homologated; impact performance exceeds standard requirements by up to 37% (linear) and 65% (rotational).

Construction

• Lightweight construction: approximately 1,540 grams (size M).
• Shell structure: multi-layer composite of 3K high-density carbon fiber and uni-directional carbon fiber reinforced with aramid fiber and fiberglass, bonded with epoxy resin; eight-piece multi-density EPS liner (six specific densities) and a raised chin bar with an EPP liner; 11-port ventilation architecture (7 intakes: 3 chin, 4 crown; 4 exhausts) with internal channels molded into the EPS and shell.
• Aerodynamic components: two interchangeable spoilers (Road and Race) with a patented release mechanism, integrated lateral winglets, and surface turbulators; Optical Class 1 shield with anti-fog and anti-scratch coatings, metal locking mechanism, Pinlock-ready with tear-off posts, and a tool-less quick-release system.
• Fit architecture: four outer shell sizes paired with four inner shells; A-Head Fitment System allowing height and angle adjustment of the crown assembly.
• Hydration routing: integrated internal channels to accommodate a hydration tube.
• Interior assembly: removable, washable padding in anti-microbial, moisture-wicking textiles; includes breath deflector and wind deflector.
