The SM7 is Alpinestars' off-road racing helmet, built around a lightweight composite shell with a smooth, channel-free aerodynamic profile. It stands out for its 20 ventilation ports (13 intakes, 7 exhausts), the A-Head fitment and visor detaching system, and PLASMA padding at the lower shell edge to soften contact with the collarbone area. The EPS has a cutaway on the left side and speaker recesses on both sides for intercom systems, and the removable, washable liner plus interchangeable cheek pads let riders tune the fit. It suits motocross and off-road riders who want strong airflow and crash-focused design over a bare-bones budget lid.

The Alpinestars SM7 is a gloss black, solid-color MX helmet for off-road riding, including ATV and UTV. It has a lightweight composite shell with an aerodynamic profile. The shell has no external channels or features that could act as a load point in an impact.
The shell's curvature reduces friction on impact, which allows deflection and transfers energy away from the rider's head. PLASMA technology sits at the lower edge of the shell and in the side pads to absorb shock near the collar bone area. The visor detaches automatically from the shell when impact energy exceeds 15 joules, regardless of direction.
The helmet has 20 intake and exhaust ports for ventilation. The linings are removable, and the fabrics have antimicrobial treatments. The top pad adjusts in height with the A-Head system. The cheek pads are 3D foam with an emergency extraction system (ERS). Alpinestars replacement cheek pads are available in all thicknesses and fit all shell sizes.
