Alpinestars SM5 Helmet Features:
CONSTRUCTION
An engineered raised area with padding effectively reduces the 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, irrespective of the angle of impact.
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 lining and cheek padding to offer 6 unique sizes and to ensure the best fitment and protection.
Revised the medium, large, XL, and 2XL ICM'er shell volume to be around 3% wider to make the helmet easier to put on and take off, where the increase in helmet volume has also improved the impact management performance which is now 44% lower than the regular-speed threshold.
SAFETY
For the new ECE 22.06 standard, the SM5 achieves a 44% better regular-speed impact rating compared to the current 33% figure, as well as a 32% better ICM'-speed, and 31% better high-speed linear impact score than the prevailing standard.
The inner and outer surfaces are engineered to minimise the effects of oblique impacts. To help fight and mitigate those rotational impact forces, Alpinestars has designed yet another proprietary technology creating an ICM' friction surface on the inner surface of the EPS liner. For the ECE 22.06 standard, which now includes the rotational oblique impact rating, the SM5 scores 70% under the new regulation.
KEY FEATURES
Multiple density inner liner to ensure the correct density in the correct area for enhanced impact absorption.
Redesigned chin bar's new profile, where the base area has been specifically sculpted to give a relief section, raised to clear the collarbone, with a new softer EPS liner which extends beyond the helmet shell itself, and is covered by a more flexible rubber compound providing a reduced chance of any sort of collarbone injury.
Patented visor release system ensures the visor is released with the correct pre-determined amount of force, irrespective of the angle of impact.
Maximised ventilation and high levels of heat transfer exchange thanks to multi-air inlets and exhaust ports.
The ECE version of the SM5 helmet weighs 1,350 grams for a size medium, and 1420 grams for the ECE DOT version with shield.
The visor has been designed to direct air into the ports for enhanced airflow.
22.06 and ECE R 22.06/DOT.
