Alpinestars Honda S-M5 Helmet

The all-new Honda SM5 ECE 22.06 / DOT Helmet has been designed to provide MX riders with a helmet that is safe and purposefully designed to deliver optimal protection and comfort. The lightweight Honda SM5 Helmet features a thermo-injected shell incorporating a special polymer blend enhanced by varying degrees of thickness that is engineered to deliver the optimal combination of impact protection and light weight. The inner liner features a 7-piece expanded polystyrene (EPS) construction including five different densities of EPS designed to ensure the correct density in the correct area for enhanced impact absorption.

  • An engineered raised area with padding effectively reduces the forces transmitted to the collarbone and a patented visor release system that ensures the visor is released with the correct pre-determined amount of force, irrespective of the angle of impact.
  • Revised the medium, large, XL, and 2XL lower shell volume to be around 3% wider to make the helmet easier to put on and take off, where the increase in helmet volume has also improved the impact management performance which is now 44% lower than the regular-speed threshold.
  • For the new ECE 22.06 standard, the SM5 achieves a 44% better regular-speed impact rating compared to the current 33% figure, as well as a 32% better low-speed, and 31% better high-speed linear impact score than the prevailing standard.
  • Multiple density inner liner to ensure the correct density in the correct area for enhanced impact absorption.
  • Redesigned chin bar’s new profile, where the base area has been specifically sculpted to give a relief section, raised to clear the collarbone, with a new softer EPS liner which extends beyond the helmet shell itself, and is covered by a more flexible rubber compound providing a reduced chance of any sort of collarbone injury.
  • Patented visor release system ensures the visor is released with the correct pre-determined amount of force, irrespective of the angle of impact.
  • Maximized ventilation and high levels of heat transfer exchange thanks to multi-air inlets and exhaust ports.
  • The visor has been designed to direct air into the ports for enhanced airflow.
  • ERS Emergency Release System cheek pads.
  • Hydration hose routing loops to facilitate hydration system mounting.
  • The ECE version of the Honda SM5 Helmet weighs 1,350 grams for a size medium, and 1420 grams for the ECE DOT version with shield.
