• Engineered for peak performance on both track and road, the lightweight S-R7 Helmet blends cutting-edge carbon composite construction with Alpinestars’ technologies
• Its advanced aerodynamics, optimized airflow, and precision-engineered EPS liner ensure superior protection and all-day riding comfort

Outer Shell

• Features an advanced multi-composite shell construction using pre-preg epoxy resin for maximum strength and performance
• Its carbon, aramid fiber, and fiberglass layers deliver lightweight yet ultra-protective performance with excellent energy dissipation, radial strength, and penetration resistance
• The streamlined aerodynamic design includes collarbone recesses on each side, fitted with two PLASMA inserts designed to offer high-performance shock absorption and reduce the risk of injuries during a slide
• Engineered for exceptional visibility, the S-R7 offers 220° peripheral vision and 57° vertical vision, enhanced by an optimized eye port and head position
• Inner Shell
• The inner shell features a multi-density EPS liner with seven pieces in six densities, strategically positioned for optimal impact absorption
• The EPS liner is engineered with a dimension specific to each helmet size, matching with the three different outer shell sizes
• The EPS surface is flush and features Alpinestars' coating, developed to deliver proven rotational impact protection
• This low-friction slip plane is designed to mimic the brain’s natural cerebrospinal fluid — the body’s inherent defense against oblique impacts
• By reducing rotational acceleration of the brain within the skull during an impact, this technology helps decrease the risk of concussion and other brain injuries

Aerodynamics

• The S-R7 Helmet delivers ultra-low drag and exceptional high-speed stability, reducing neck strain
• Its aerodynamically optimized shell features an integrated spoiler developed to minimize turbulence and drag, while lateral winglets further enhance stability and further reduce drag

Ventilation

• The S-R7 is optimized for airflow with a total of 10 ventilation ports: 6 intake ports (3 in the chin guard and 3 on the top of the head) regulated by a slidable top vent mechanism, plus 4 exhaust ports (2 lateral ports on the chin bar and 2 at the rear of the helmet)
• The incoming air from the chin vents is channeled towards the inner side of the shield, effectively preventing fogging and misting
• The entire top vent section is slidable, allowing riders to reveal three air channels for maximum airflow and cooling performance
• Chin Bar Extractor Vents are designed to efficiently extract humid air from inside the helmet

Shield

• The helmet is fitted with an ECE 22.06 homologated, optical Class 1 shield, with double-sided anti-scratch treatment
• Shield thickness varies from 1.6 mm on the sides to 2.6 mm in the center
• It includes pins to attach a Pinlock® 120XLT 100% Max Vision lens
• The visor can be quickly changed or removed using a secure, tool-less quick-release system that allows pivotal rotation to ensure a complete seal against the helmet’s rubber window trim

A-Head Fitment System

• A micro-adjustable pad connected to the helmet's inner EPS liner enables an ultra-specific setup that adapts to how deeply the rider's head sits in the helmet and how far forward or backward it is tilted, delivering the ultimate personalized fit

Removable Lining

• All linings are removable and washable, and feature fabrics with anti-microbial treatments
• Cheek Pads featuring fitted 3D foam with channels to accommodate glasses, an Emergency Release System (ERS), and an integrated hydration tube channel

Accessories

• Clear visor, Pinlock® 120 MaxVision™ anti-fog lens, breath deflector, chin curtain, and helmet soft bag

A-Connect Ready

• The S-R7 Helmet is engineered for seamless integration with the Alpinestars A-Connect Communication System, delivering advanced communication—including Mesh 3.0 intercom—along with premium sound quality powered by Harman Kardon high-definition speakers and advanced noise reduction
