The Alpinestars S-R7 A-Core Helmet is engineered for riders who demand a perfect balance of track-level performance and real-world riding comfort. Sharing its DNA with the top-tier SR10 race helmet, the S-R7 is tuned for a more upright riding position while maintaining aggressive aerodynamic efficiency and race-proven protection.
Its advanced shell construction combines fiberglass, UD carbon, and carbon-aramid fibers, bonded through a high-performance pre-preg epoxy process. This multi-composite structure delivers outstanding strength-to-weight performance, resulting in a lightweight yet highly protective helmet built for demanding conditions. The streamlined exterior eliminates unnecessary surface channels, reducing drag while improving impact performance consistency.
Wind tunnel-developed aerodynamics include an integrated rear spoiler and lateral winglets that help reduce turbulence and improve high-speed stability. A recessed collarbone zone is also engineered into the shell design to reduce the risk of injury during sliding impacts, adding an extra layer of real-world safety protection.
Comfort and fit are highly customizable thanks to the patented A-Head system, which allows riders to fine-tune helmet height and angle for a more precise, personalized fit. The interior features fully removable, washable, and antimicrobial liners with strategically designed foam padding for improved impact management, comfort, and airflow. Integrated channels also accommodate eyewear and hydration systems, making it suitable for both road and endurance riding.
Ventilation is handled by a 10-port airflow system, including adjustable intake vents and rear exhaust outlets integrated into the spoiler design. This ensures consistent cooling and effective moisture control, even in high-intensity riding conditions. A chin vent system actively directs airflow to reduce visor fogging, while rear extractors efficiently remove warm air.
Vision clarity is ensured through an ECE 22.06 homologated optical Class 1 visor, paired with a Pinlock 120XLT anti-fog lens included in the box. The quick-release visor system allows tool-free changes, while a secure locking mechanism prevents accidental detachment at speed.
Safety is at the core of the S-R7 A-Core, featuring a multi-density EPS liner with advanced energy-dissipating zones and Alpinestars’ patented PLASMA collarbone protection inserts. The helmet also includes rotational impact management technology, an emergency quick-release system, and exceeds ECE 22.06 rotational acceleration standards by a significant margin.
Finished with a secure stainless-steel double D-ring strap and A-Connect communication system compatibility (sold separately), the S-R7 A-Core is built for riders who want race-level engineering with everyday usability.
