The SM7 Dasher is Alpinestars' off-road racing helmet, built around a lightweight composite shell with a smooth, channel-free profile meant to deflect rather than snag on impact. Its standout feature is heavy ventilation: 20 intake and exhaust ports plus a wide eye port for goggles. It also carries PLASMA padding at the lower shell edge to soften collar bone contact, and the EPS is cut for intercom speakers. It suits motocross and off-road riders who want a well-vented race helmet and run a communicator; against rivals it trades the brand's premium finish for a fit that depends on swapping cheek pads.

The Alpinestars SM7 Dasher is an off-road MX helmet for adult riders. It has a lightweight, aerodynamic composite shell. The shell is smooth, with no external channels or features that could act as a load point in an impact. Its curvature reduces friction on impact and helps deflect and transfer energy.
The helmet has 20 intake and exhaust ports for ventilation, not counting the eye port: 13 intakes and 7 exhausts. PLASMA technology sits at the lower edge of the shell, in the side pads, to absorb shock near the collar bone area. The visor is designed to detach automatically from the shell when impact energy exceeds 15 Joules, regardless of direction.
Inside, the top pad is removable and adjustable in height with the A-Head system. The crown pad and neck pad are elastically connected for better oblique impact management. The cheek pads are 3D foam with an emergency extraction system (ERS) and a channel for a hydration tube. The linings are removable and have antimicrobial fabric treatments. They can be washed by hand with warm water and neutral soap. The helmet has a cutaway on the left side of the EPS and earphone recesses on both sides for intercom systems and speakers.
