Alpinestars Motocross Helmets

The Alpinestars Supertech M10 Era Helmet sets a new benchmark in safety, comfort, and performance. It is built for riders who demand the best. The S-M10 is lightweight, yet it delivers maximum protection. Its smooth, aerodynamic shell eliminates external channels. As a result, it reduces friction on impact and spreads energy away from the skull, neck, and spine.

Furthermore, the helmet features a multi-shell sizing system. Each size has its own dedicated shell to ensure the perfect fit. Four shell sizes (S, M, L, XL) cover six consumer sizes (XS–XXL). Consequently, comfort improves, weight reduces, and impact protection increases. In addition, the redesigned chin bar and softer EPS liner reduce the risk of collarbone injuries. The patented A-Head Fitment System allows easy height and angle adjustment, giving riders a secure, personalised fit.

Ventilation is exceptional. Twenty-eight intake and exhaust ports channel air efficiently. Moreover, the helmet includes the eject removal system for safety. It weighs 1260g standard, 1310g with side pads, and 1370g with visor extension. The S-M10 exceeds ECE 22.06 and DOT standards, ensuring reliable protection in all conditions.

Construction & Safety

• The shell uses a multi-composite lay-up:
  • 3K Carbon: Dissipates energy effectively
  • Uni-directional Carbon: Adds radial strength and controlled deflection
  • Aramid Fiber: Provides penetration resistance
• Together, these layers, bonded with epoxy resin and paired with a 4-density EPS liner, exceed linear and oblique impact standards by 23–46%.

In conclusion, the Alpinestars Supertech M10 Era Helmet combines advanced technology, lightweight performance, and superior protection. Therefore, riders can trust it for comfort, safety, and confidence on every ride.

Sizing

To determine which helmet size fits you best, measure the widest circumference of your head using a flexible measuring tape or piece of string; approximately 2cm above your eyebrows and ears as illustrated below. If your head measurement falls between two sizes, it is generally recommended to select the smaller of the two.

For maximum safety and comfort, take note of the following points when fitting the helmet (and securely fastening the chin strap):

• Helmet may take some effort to slide over your head, but should not be overly difficult
• Should fit snuggly around the crown of your head without creating uncomfortable pressure points
• The top padding presses on the top of your head
• The cheek pads press against your cheeks, so that your teeth touch the inside of your cheeks when opening / closing your mouth
• There should be no space to slide two fingers between the helmet and your temple
• Hold the helmet on either side and without moving your head, try to move the helmet up and down, and side to side. It should not be easy to move and you should feel the skin of your head and face being pulled
• Your eyes should be located in the center of the helmet's viewpoint
