The SM7 Core is Alpinestars' off-road racing helmet, built around a lightweight composite shell with an aerodynamic profile and no external channels that could catch in a crash. It is heavily ventilated, with 20 intake and exhaust ports, and adds PLASMA padding at the lower shell edge to soften impact near the collarbone. The A-Head fitment system and interchangeable cheek pads let riders tune the fit, and the EPS has a cutaway and speaker recesses for an intercom. It suits motocross and off-road riders who want a race-focused helmet with strong airflow and crash protection, and it competes with premium motocross lids on ventilation and fit adjustment rather than on extras.

The SM7 Core is an off-road helmet built for MX, ATV and UTV riding. It has an aerodynamic composite shell with a smooth profile, free of external channels and features that could act as a load point in an impact. The shell's curvature reduces friction on impact, helping deflect and transfer energy.
The helmet has 20 intake and exhaust ports, not including the eye port: 13 intakes and 7 exhausts. 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 when it is subjected to an impact energy greater than 15 Joules, regardless of the direction.
The linings are removable and can be washed by hand with warm water and neutral soap. The fabrics have antimicrobial treatments. The top pad is removable and adjustable in height through the A-Head system. A cutaway on the left side of the EPS and earphone recesses on both sides accommodate intercom systems and speakers.
