Ride with confidence in the Alpinestar SM5 Action 2 Helmet in Glossy Bright Red and Blue. Its lightweight thermoplastic shell and multiple-density inner liner provide advanced impact absorption while reducing forces on your collarbone. The patented visor release system ensures your visor safely disengages during an impact, giving you added safety on every ride.
Designed for both comfort and performance, the SM5 Action 2 offers six size options for a precise fit, along with a slightly wider lower shell to make it easier to put on and take off. Multiple air inlets and exhaust ports keep airflow high, while proprietary low-friction inner surfaces help minimize rotational impact forces. ECE 22.06 certified, this helmet combines top-level protection, ventilation and a bold color scheme for riders who demand both safety and style.
Features:
- 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.
- 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.
- Revised the medium, large, XL, and 2XL lower 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.
- 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 low-speed, and 31% better high-speed linear impact score than the prevailing standard.
- 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.
- Maximized 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.
- The visor has been designed to direct air into the ports for enhanced airflow.
- The SM5 conforms to ECE R 22.06.
- The inner and outer surfaces are engineered to minimize the effects of oblique impacts. To help fight and mitigate those rotational impact forces, Alpinestars has designed a proprietary technology by creating a low 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.
- Patented visor release system ensures the visor is released with the correct pre-determined amount of force, irrespective of the angle of impact.
