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

Multi-composite shell: combines carbon, aramid fiber, and fiberglass with pre-preg epoxy resin to deliver lightweight strength, energy dissipation, radial strength, and penetration resistance.
PLASMA inserts: integrated into the collarbone recesses to provide high-performance shock absorption and help reduce injury risk during a slide.
Wide field of vision: provides 220° peripheral and 57° vertical vision through an optimized eye port and rider head position for improved awareness on track and road.
Size-specific EPS liner: uses seven pieces in six densities, precisely matched to each helmet size and its corresponding outer shell for optimized impact absorption.
Low-friction slip plane: Alpinestars’ patented EPS coating helps reduce rotational acceleration during oblique impacts, exceeding the ECE 22.06 Peak Rotational Acceleration standard by 80%.

ECE 22.06 homologated: the S-R7 meets ECE 22.06 helmet standards.
Optical Class 1 shield: ECE 22.06 homologated shield features double-sided anti-scratch treatment and variable thickness from 1.6 mm at the sides to 2.6 mm at the center.
Pinlock® compatible: shield pins accommodate a Pinlock® 120XLT 100% Max Vision lens.
Secure shield locking: premium polymer locking lever helps prevent unwanted shield detachment during impacts or crashes and can be secured closed through the frontal metal hook.
Tool-less visor release: secure quick-release system allows easy visor removal and replacement without tools.
Shield sealing mechanism: side mechanisms allow the shield to rotate and move to seal completely against the helmet’s rubber window trim.
A-Head Fitment System: patented micro-adjustable system connected to the EPS liner allows helmet height, depth and fore-aft angle to be tuned to the rider.
Emergency Release System: 3D foam cheek pads incorporate ERS for emergency helmet removal.

Pre-preg composite construction: carbon, aramid fiber and fiberglass layers are bonded with advanced epoxy resin pre-applied directly to the pre-preg fibers.
Aerodynamic shell structure: delivers ultra-low drag, high-speed stability and reduced neck strain.
Integrated road spoiler: developed using computer-aided pressure visualization in a full-scale wind tunnel to reduce turbulence and drag.
Lateral winglets: integrated into the outer structure to further support high-speed stability and reduce aerodynamic drag.
10-port ventilation system: comprises six intake ports—three in the chinguard and three at the top—and four exhaust ports, with two at the chin bar and two at the rear.
Adjustable chin vents: two closable front openings direct airflow toward the inner shield surface to help prevent fogging and misting.
Central chin intake: additional closable intake beneath the shield lock directs air toward the inner shield and uses a removable rubber bung.
Sliding top vent: movable upper section reveals three internal air channels for increased airflow and cooling.
Chin-bar extractor vents: two lateral exhaust ports remove humid air from the helmet interior.
Rear extractor vents: two exhaust ports integrated into the rear spoiler support effective hot-air extraction.
Removable comfort lining: all linings are removable and washable and feature anti-microbial fabric treatments.
3D cheek pads: fitted foam construction includes eyewear channels, an Emergency Release System and an integrated hydration tube channel.
Lightweight construction: size M weighs 1,390 g / 3.06 lb.
