Alpinestars Supertech R7 Adult Street Helmets

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.

Homologated to ECE 22.06 and DOT standards, the S-R7 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
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 unique dimension specific to each helmet size, matching with the three different outer shell sizes
The EPS surface is flush and features Alpinestars' patented 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. The S-R7 exceeds the ECE 22.06 Peak Rotational Acceleration standard by 80%
ECE 22.06 and DOT homologated
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
The S-R7 features Alpinestars' unique and patented A-Head fitment system, allowing riders to fine-tune both the height and angle at which the helmet sits on the head. 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 INCLUDED
Each solid and graphic colorway S-R7 helmet comes with the following accessories in the box: Clear visor (pre-attached to helmet), Pinlock 120 MaxVision anti-fog lens, breath deflector (pre-attached to helmet), 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 (sold seperately), delivering advanced communication-including Mesh 3.0 intercom-along with premium sound quality powered by Harman Kardon high-definition speakers and advanced noise reduction
