Item code: 300053

The Alpinestars S-M5 Rayon is the result of five years of round-the-clock study, development and testing. The lightweight helmet features a thermo-injected shell incorporating a special polymer blend enhanced by varying degrees of thickness that is engineered to deliver the best protection on the market. The five density EPS liner ensures the correct density in the correct area for enhanced impact absorption.

  • Lightweight outer shell is constructed from a technologically advanced impact-resistant thermoplastic in two sizes
  • The inner and outer surfaces are engineered to minimize the effects of oblique impacts
  • Maximized ventilation and high levels of heat transfer exchange thanks to multi-air inlets and exhaust ports
  • Patented visor release system ensures the visor is released with the correct pre-determined amount of force
  • Multiple density inner liner to ensure the correct density in the correct area for enhanced impact absorption
  • Side shell couple with soft EPS foam prevents damage to collarbone in the event of a crash
  • Emergency release system and removable cheek pads permit the safe and easy removal of the cheek pads while the helmet is still on, while the 3D contoured foam ensures rider comfort
  • Stainless steel D-rings to ensure a tight and secure fit
  • Hydration tube channels are integrated into the helmet’s cheek pads for convenience and performance
  • Anti-microbial liner is removable and washable
  • Soft textile chin strap is 26mm and is wider than certification requirements for optimal safety and rider comfort
  • Removable comfort liner with Silverplus® treated anti-bacterial fabrics for excellent moisture wicking, effectively drawing perspiration away from the skin
  • The SM5 helmet conforms to ECE homologation
