Designed to deliver high performance on both track and road, the lightweight S-R7 helmet combines advanced aerodynamics, optimized airflow, cutting-edge materials, and Alpinestars’ patented PLASMA technology to ensure superior protection.

The helmet is also designed to integrate seamlessly with A-Connect—Alpinestars’ communication system—which utilizes a second-generation Harman Kardon audio setup featuring 40mm speakers and advanced AI-based noise cancellation technology, delivering an exceptional listening experience.
Key Features

Multi-layer composite shell: combines carbon, aramid fiber, and fiberglass with pre-impregnated (pre-preg) epoxy resin to provide lightness, strength, energy dissipation, radial rigidity, controlled deformation, and penetration resistance.
Aerodynamic shell profile: the smooth external design eliminates external channels and potential load points during an impact, while the collarbone cutout helps reduce contact between the shell and the body during a slide.
Multi-density EPS inner shell: seven EPS sections with six different densities are strategically positioned to ensure targeted impact absorption, with sizes specific to each helmet size.
PLASMA collarbone inserts: two patented PLASMA sections are integrated into the collarbone cutouts, offering additional impact absorption in this critical area.
Rotational impact management: specific EPS geometry and a special internal structure work in synergy with the specially developed inner liner surface to reduce rotational acceleration transmitted to the rider's head. A-Connect ready: designed for seamless integration with Alpinestars’ A-Connect communication system, featuring Mesh 3.0 intercom, second-generation 40mm Harman Kardon speakers, and an advanced noise-reduction system.
Comprehensive accessory package: includes a clear visor, Pinlock® 120 MaxVision™ anti-fog lens, breath deflector, nose guard, and a soft helmet bag.
