Alpinestars SM5 SAIL

• • 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.
  • Maximized ventilation and high levels of heat transfer exchange thanks to multi-air inlets and exhaust ports.
  • The ECE version of the SM5 helmet weighs 1,350 grams for a size medium.
  • The visor has been designed to direct air into the ports for enhanced airflow.
  • The SM5 conforms to ECE R 22.06.
