Helmet Alpinestars S-M3 Youth Red

The SM3 Junior is the latest evolution of the Alpinestars MX helmet, anatomically developed for young motocross, enduro, and off-road riders. Ref. 83012273206Y

The Alpinestars S-M3 youth helmet, featuring adult-range technology, combines lightweight construction, advanced impact management, and high-flow ventilation to perform confidently in demanding conditions. Its youth fit and adaptable sizing provide lasting comfort, stability, and protection as the rider and their skills evolve.

The Alpinestars S-M3 youth helmet offers safety and comfort for younger riders.

Specifications:

  • Visor air channeling: the shape of the visor helps direct air into the helmet’s vents, promoting a stronger internal airflow when temperatures and pace rise.
  • Hydration tube routing: integrated channels in the cheek pads keep the hose properly positioned, making it easier to drink on the go without losing focus.
  • Recycled comfort liner: the interior liner uses recycled materials to offer a softer feel against the skin with a lower-impact construction approach.
  • Growth-adaptive fit: Youth Medium and Youth Large share the same EPS size, allowing the helmet to be reconfigured as the rider develops.
  • Dedicated youth fit: Youth Small uses its own smaller EPS size and specific cheek pad sizing to provide a fit tailored for younger riders.
  • The multi-density inner liner places the right density in the correct zone to enhance impact absorption.
  • The inner and outer surfaces are designed to minimize the effects of oblique impacts.
  • Alpinestars’ patented low-friction coating on the inner surface of the main EPS liner reduces rotational acceleration forces generated by certain oblique impacts, acting as a slip plane.
  • The patented visor release system is calibrated to release with a predetermined amount of force to help reduce the forces transmitted to the rider’s neck during an impact.
  • The 25 mm chin strap provides secure helmet retention.
  • Alpinestars’ internal safety standard applies additional testing to the chin area beyond homologation requirements, with optimized shell thickness and reinforced helmet structure at the chin bar.
  • The Emergency Release System and removable cheek pads are integrated to allow a controlled extraction of the pads, with 3D-contoured foam used in the interior assembly.
  • Stainless steel D-rings are used for the retention system.
  • The helmet complies with DOT certification and ECE 2206 homologation.
  • Approximate weight: 1,820 g.
