What Safety Technologies Are Built into the Alpinestars SM7?

Key safety features explained

PLASMA Side Pad Integration

PLASMA side pad integration is Alpinestars' patented impact-management technology that places energy-absorbing PLASMA material within the helmet's side pads. The system is engineered to help manage shock absorption around the collarbone-area zone while maintaining rider comfort and helmet stability.

Patented A-Head Fitment System 

The A-Head Fitment System is an adjustable helmet retention mechanism that allows riders to fine-tune both vertical position and helmet angle. Proper positioning improves overall comfort while helping the helmet sit correctly to maximize its intended protective performance.

Other important safety features include:

• Eject Removal System Ready design with a removable EPS insert to accommodate an eject helmet removal system.
• Engineered shell and EPS construction designed to work together for optimized impact energy management.

The Alpinestars SM7 helmet combines lightweight composite construction, advanced fit customization, modern impact-management technologies, and practical rider-focused features into a premium off-road helmet.
