Helmet Alpinestars SM5 Corp Red Black White

Upgrade your riding experience with the Alpinestars SM5 Corp helmet.

Specifications:

• Collarbone protection: a raised, padded area is designed to effectively reduce forces transmitted to the collarbone, while a patented visor release system ensures the visor releases with the correct predetermined amount of force, regardless of impact angle.
• Revised shell volume: the lower shell volume in sizes M, L, XL, and 2XL has been increased by approximately 3% for easier helmet donning and removal, while this increase in volume has also improved impact management, now 44% below the regular speed threshold.
• ECE 22.06 Certification: for the new ECE 22.06 standard, the SM5 achieves a 44% better regular speed impact rating compared to the current 33% figure, plus a 32% better low-speed linear impact score and a 31% better high-speed linear impact score than the current standard.
• Multi-density inner liner: ensures the right density in the right zone for improved impact absorption.
• Redesigned chin bar: the new chin bar profile features a specifically sculpted base to create a raised relief area that clears the collarbone, along with a new, softer EPS liner that extends beyond the helmet shell itself and is covered by a more flexible rubber compound to reduce the likelihood of collarbone injury.
• Ventilation system: maximizes ventilation and provides high levels of thermal exchange thanks to multiple air intakes and exhaust ports.
• Lightweight construction: the ECE version of the SM5 helmet weighs 1,350 grams in medium size, and 1,420 grams in the ECE/DOT version with visor.
• Visor design: it has been designed to channel air into the ports and enhance airflow.
• Available versions: the SM5 is available in 2 versions, ECE R 22.06 and ECE R 22.06/DOT.
• The lightweight outer shell is constructed from a technologically advanced impact-resistant thermoplastic in three anatomically shaped shell sizes, plus three individual EPS inner liner sizes with a combination of interior lining and cheek pads to offer 6 unique sizes and ensure the best fit and protection.
