Helmet Alpinestars SM5 Action 2 Orange Blue Yellow

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

Specifications:

• Clavicle protection and visor release: an elevated area designed with padding effectively reduces the forces transmitted to the clavicle, while a patented visor release system ensures it detaches with the correct preset amount of force, regardless of the impact angle.
• Optimized shell volume: the lower shell volume has been revised in sizes M, L, XL, and 2XL to make it approximately 3% wider, thus making it easier to put on and take off the helmet; this increase in 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 than the current figure of 33%, as well as 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 impact absorption.
• Redesigned chin bar profile: the base area has been specifically sculpted to create a raised relief section that clears the clavicle, with a new softer EPS liner extending beyond the shell itself and covered by a more flexible rubber compound, reducing the likelihood of clavicle injuries.
• Ventilation system: maximizes air circulation and thermal exchange thanks to multiple air inlets and exhaust ports.
• Lightweight: the ECE version of the SM5 helmet weighs 1,350 grams in size M, and 1,420 grams in the ECE DOT version with visor.
• Visor design: developed to channel air toward 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 interior and exterior surfaces are designed to minimize the effects of oblique impacts. To help combat and mitigate those rotational impact forces, Alpinestars has developed its own 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 preset amount of force, regardless of the impact angle.
• The lightweight outer shell is constructed from a technologically advanced impact-resistant thermoplastic in three anatomical shell sizes, plus three individual EPS liner sizes, with a combination of inner liner and Cheek Pad to offer 6 unique sizes and ensure the best fit and protection.
