Helmet Alpinestars SM5 Action 2 Red Blue White

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

Specifications:

• Clavicle protection and visor release: a raised area designed with padding effectively reduces the forces transmitted to the clavicle, while a patented visor release system ensures it is detached with the correct amount of preset 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, facilitating putting on and taking off the helmet; this increase in volume has also improved impact management, now standing 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 33% figure, as well as a result 32% better in low-speed linear impact and 31% better in high-speed linear impact than the existing standard.
• Multi-density inner liner: ensures the proper density in each area to enhance impact absorption.
• Redesigned chinbar profile: the base area has been specifically sculpted to create an elevated relief section that clears the clavicle, with a new, softer EPS liner that extends beyond the outer shell itself and is coated by a more flexible rubber compound, reducing the likelihood of clavicle injuries.
• Ventilation system: maximizes airflow and thermal exchange thanks to multiple air intakes 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: has been developed to direct 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 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 that the visor is released with the correct amount of preset 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 inner liner sizes, with a combination of interior lining and cheek pad to offer 6 unique sizes and ensure the best fit and protection.
