The Alpinestars Supertech M10 Fame Helmet is engineered as a premium motocross helmet with a focus on protection, lightweight performance, ventilation and rider comfort. Its multi-composite shell combines a high-density 3K carbon outer layer, uni-directional carbon composite for radial strength and an aramid fiber layer for penetration resistance, all bonded with epoxy resin for structural integrity and controlled energy management.

Protection extends beyond the shell with the MIPS Multi-Directional Impact Protection System and an EPS construction designed to manage impact forces. The sculpted chin bar incorporates softer EPS and flexible rubber around the lower profile to provide additional clearance around the collarbone. Removable semi-soft side pads increase the contact area during an impact, while emergency visor release and integrated eject technology are designed to assist first responders following a crash.

Alpinestars' patented A-Head Fitment System allows the helmet's angle and height to be adjusted for a more personalized position on the rider's head. Four dedicated shell sizes across the six-size range help reduce unnecessary bulk and weight, while 28 ventilation ports — 18 intake and 10 exhaust — provide extensive airflow. The result is a premium MX helmet built for riders who demand high levels of protection, comfort and performance.

The Alpinestars Supertech M10 Fame Helmet is available in sizes XS through 2XL and uses four dedicated shell sizes across the six-size range to provide a more anatomical fit with reduced unnecessary bulk.

Measure around the widest part of your head, approximately one inch above the eyebrows, and compare your measurement with the Alpinestars helmet size chart.

A properly fitted motocross helmet should feel snug and secure around the entire head without creating painful pressure points. The cheek pads should make firm contact with your cheeks, and the helmet should not move independently when you move your head.

The A-Head Fitment System allows the helmet's height and angle to be adjusted, helping fine-tune the position, balance and overall fit after selecting the correct helmet size.
