Alpinestars S-R7 A-Core Helmet- Red

Key Features

• 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.
