Helmet Alpinestars SM5 Action 2 Orange Blue Yellow

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 forces transmitted to the collarbone, while a patented visor release system ensures the visor detaches with the correct amount of preset force, regardless of the angle of impact.
• Optimized shell volume: the lower shell volume in sizes M, L, XL, and 2XL has been revised to make it approximately 3% wider, making it easier to put on and take off the helmet; this increased volume has also improved impact management, now being 44% below the regular speed threshold.
• ECE 22.06 Performance: for the new ECE 22.06 standard, the SM5 achieves a regular speed impact rating 44% better than the current figure of 33%, as well as a 32% better result in low-speed linear impact and a 31% better result in high-speed linear impact compared to 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 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 air circulation and heat 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 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 combat and mitigate those rotational impact forces, Alpinestars has developed its own technology by creating a low-friction surface on the inside 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 an advanced impact-resistant thermoplastic in three anatomical shell sizes, plus three individual EPS interior liner sizes, with a combination of inner liner and cheek pad to offer 6 unique sizes and ensure the best fit and protection.
