Alpinestars S-M5 RASH 22.06 Fluo Yellow Navy Glossy Motorcycle Cross Enduro Helmet

The SM5 helmet was designed to provide MX riders with a safe and specially designed helmet to offer optimal protection and comfort. The lightweight SM5 helmet features a thermo-injected shell that incorporates a special polymer blend enhanced by varying degrees of thickness that is designed to offer the optimal combination of impact protection and lightness, while the five-density EPS liner ensures the correct density in the area corrected for better shock absorption.

Data sheet:

• An engineered raised area with padding effectively reduces forces transmitted to the collarbone and a patented visor release system that ensures the visor is released with the correct pre-determined amount of force, regardless of impact angle.
• Revised the Medium, Large, XL and 2XL bottom shell volume to be approximately 3% wider to make the helmet easier to put on and take off, where the increased helmet volume also improved the handling performance of the impacts that are now 44% lower than the normal speed threshold.
• Per the new ECE 22.06 standard, the SM5 achieves a normal speed impact score that is 44% better than the current figure of 33%, as well as a linear impact score that is 32% better at low speed and 31% better at high speed. speed compared to the prevailing norm.
• Multiple density inner lining to ensure the correct density in the correct area for better impact absorption.
• New redesigned chin bar profile, where the base area has been specially sculpted to give a raised section, raised to free up the collarbone, with a new softer EPS liner that extends beyond the helmet shell itself and is covered with a more flexible rubber compound that provides a reduced chance of any type of collarbone injury.
• Maximized ventilation and high levels of heat exchange thanks to multiple vents and exhaust ports.
• The ECE version of the SM5 helmet weighs 1,350 grams for a medium size, and 1420 grams for the ECE DOT version with visor.
• The visor was designed to direct air into the ports for better airflow.
• 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 those rotational impact forces, Alpinestars engineered proprietary technology creating a low-friction surface on the inner surface of the EPS liner. For the ECE 22.06 standard, which now includes oblique rotational impact assessment, the SM5 scores 70% under the new regulation.
• The patented visor release system ensures that the visor is released with the correct pre-determined 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 inner liner sizes with a combination of inner liner and cheek padding to offer 6 unique sizes and to ensure the better fit and protection.
