Alpinestars S-M5 Solar Flare Helmet - Black/Red Fluoro/Yellow Fluoro

Alpinestars SM5 Helmet

The all-new Alpinestars SM5 Helmet is the result of over five years of rigorous research, design, and testing — created with one goal: to deliver exceptional protection, comfort, and ventilation in a lightweight, race-ready package. Every element of the SM5 has been meticulously engineered to ensure optimal safety performance for off-road and motocross riders.


Advanced Construction

  • Lightweight Shell: Constructed from a thermo-injected advanced polymer blend, developed for outstanding impact resistance while minimizing weight.

  • Dual Shell Sizes: Ensures a precise anatomical fit and improved comfort across all head shapes.

  • Five-Density EPS Liner: Strategically layered to deliver the correct density in each zone, maximizing impact absorption where it’s needed most.

  • Optimized Energy Management: The inner and outer surfaces are engineered to reduce rotational and oblique impact forces, lowering the risk of brain and neck injuries.


Innovative Safety Features

  • Patented Visor Release System:
    Designed to release the visor under a specific, pre-determined amount of force — regardless of the angle of impact — helping to prevent rotational energy transfer during a crash.

  • Collarbone Protection:
    A specially raised side shell section combined with soft EPS foam reduces the chance of collarbone injury on impact.

  • Emergency Release System:
    Allows safe and easy cheek pad removal while the helmet remains on the rider.

  • Wide 26mm Chin Strap:
    Exceeds certification standards for greater comfort and enhanced security.

  • Stainless Steel D-Rings:
    Provide a secure and reliable fit in all conditions.


Ventilation & Comfort

  • Advanced Airflow System:
    Features multiple intake and exhaust ports, with a visor design that actively channels air through the helmet for maximum cooling and heat exchange.

  • Silverplus® Liner:
    Moisture-wicking, antibacterial, and removable liner keeps the interior fresh while effectively managing perspiration.

  • 3D Contoured Foam Padding:
    Delivers an adaptive, secure fit for enhanced rider comfort and reduced pressure points.

  • Hydration System Compatible:
    Integrated channels in the cheek pads allow for easy routing of hydration tubes.


Fit & Certification

  • Lightweight Performance:
    Weighs just 1260g (ECE) and 1380g (DOT) in size Medium.

  • Dual Certification:
    Meets both DOT and ECE 22.05 standards, making it approved for use worldwide.


The Alpinestars SM5 Helmet blends advanced safety technology, premium materials, and rider-focused design for a helmet that delivers world-class protection without compromise. Whether on the track or the trail, it’s built to keep you safe, cool, and comfortable — ride after ride.
