Helmet Alpinestars SM5 Action 2 Black Yellow Red

Elevate your riding experience with the Alpinestars SM5 Action 2 helmet.

Specifications:

• Collarbone protection and visor release: a raised area designed with padding effectively reduces the forces transmitted to the collarbone, while a patented visor release system ensures it detaches with the correct amount of preset force, regardless of the angle of impact.
• Optimized shell volume: the lower shell volume has been revised in sizes M, L, XL, and 2XL to make it approximately 3% wider to facilitate putting on and removing the helmet; this increased volume has also improved impact management, now sitting 44% below the regular speed threshold.
• ECE 22.06 performance: for the new ECE 22.06 standard, the SM5 achieves an impact rating at regular speed 44% better compared to the current figure of 33%, in addition to a result 32% better in low-speed linear impact and 31% better in high-speed linear impact than the current standard.
• Multi-density inner liner: ensures the proper density in each area to enhance shock absorption.
• Redesigned chin bar profile: the base area has been specifically sculpted to create a raised relief section that clears the collarbone, with a new softer EPS liner that extends beyond the shell itself and is covered by a more flexible rubber compound, reducing the likelihood of collarbone injuries.
• Ventilation system: maximizes airflow and heat exchange thanks to multiple air intakes and extraction ports.
• Controlled weight: the ECE version of the SM5 helmet weighs 1,350 grams in size M, and 1,420 grams in the ECE DOT version with a visor.
• Visor design: developed to direct air towards the ports and improve airflow.
• Available versions: the SM5 is available in 2 versions, ECE R 22.06 and ECE R 22.06/DOT.
• The inner and outer surfaces are designed to minimize the effects of oblique impacts. To help fight and mitigate those rotational impact forces, Alpinestars has developed proprietary technology by creating a low-friction surface on the inner face of the EPS liner. For the ECE 22.06 standard, which now includes rotational oblique impact rating, the SM5 scores 70% below the new regulation.
• The patented visor release system ensures the visor releases with the correct amount of preset force, regardless of the angle of impact.
• The lightweight outer shell is constructed from a technologically advanced impact-resistant thermoplastic in three anatomical shell sizes, as well as three individual EPS inner liner sizes, with a combination of inner liner and Cheek Pad to offer 6 unique sizes and ensure the best fit and protection.
