Alpinestars SM5 BOND

• 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.
