Helmet Alpinestars SM5 Sail Yellow Blue Grey

Elevate your riding experience with the Alpinestars SM5 Sail helmet.

Specifications:

• Collarbone protection and visor release: a raised, padded area effectively reduces the forces transmitted to the collarbone, while a patented visor release system ensures the visor detaches with the correct amount of predefined force, regardless of the impact angle.
• Revised shell volume: the lower shell volume in sizes M, L, XL, and 2XL has been increased by approximately 3% to facilitate putting on and taking off the helmet; this volume increase has also improved impact management, now 44% below the standard speed threshold.
• ECE 22.06 approval: for the new ECE 22.06 standard, the SM5 achieves a standard speed impact rating 44% better compared to the current figure of 33%, as well as a 32% better performance at low speed and 31% better at high speed in linear impact than the current standard.
• Multi-density inner liner: ensures the correct density in the appropriate area to improve impact absorption.
• Redesigned chin bar: the new chin bar profile features a specifically sculpted base with a raised relief section to clear the collarbone, along 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 injury.
• Ventilation system: maximized ventilation and high level of heat exchange thanks to multiple air inlets and exhaust ports.
• Optimized weight: the ECE version of the SM5 helmet weighs 1,350 grams in medium size, and 1,420 grams for the ECE DOT version with visor.
• Visor design: the visor has been designed to direct air to 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 internal and external surfaces are designed to minimize the effects of oblique impacts. To help combat and mitigate these rotational impact forces, Alpinestars has designed a patented technology by creating a low-friction surface on the inner surface of the EPS liner. For the ECE 22.06 standard, which now includes rotational oblique impact rating, the SM5 scores a result 70% below the new regulation.
• The patented visor release system ensures the visor releases 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 inner liner and cheek pads to offer 6 unique sizes and ensure the best fit and protection.
