Honda SM5 Helmet

• 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, and 1420 grams for the ECE DOT version with shield.
• The visor has been designed to direct air into the ports for enhanced airflow.
• The SM5 is available in 2 versions ECE R 22.06 and ECE R 22.06/DOT.

• The inner and outer surfaces are engineered to minimize the effects of oblique impacts. To help fight and mitigate those rotational impact forces, Alpinestars has designed a proprietary technology by creating a low friction surface on the inner surface of the EPS liner. For the ECE 22.06 standard, which now includes the rotational oblique impact rating, the SM5 scores 70% under the new regulation.
• Patented visor release system ensures the visor is released with the correct pre-determined amount of force, irrespective of the angle of impact.

• Lightweight outer shell is constructed from a technologically advanced impact resistant thermoplastic in three anatomical shell sizes, plus three individual EPS inner liner sizes with a combination of inner lining and cheek padding to offer 6 unique sizes and to ensure the best fitment and protection.
