The S-M3 off-road motorcycle helmet is designed for MX, enduro, and off-road use; an ideal entry-level motocross helmet. This motorcycle helmet combines user-friendliness, comfort, and impact protection at a solid level, all at an excellent price.
The thermo-injected motorcycle helmet shell is made from a special polymer blend with varying thicknesses, designed to achieve the optimal balance between impact resistance and low weight. The S-M3 motorcycle helmet weighs around 1,430 grams. Both the inner and outer surfaces are shaped to minimise the effects of angled impact.
You can see right through the S-M3 motorcycle helmet. With no fewer than ten air inlets and seven outlets, which are all permanently open, this motorcycle helmet ensures maximum ventilation and effective heat dissipation.
We could fill a whole paragraph with the technical details on density, volume, impact performance, and rotational acceleration forces. One feature is optimised to enhance another. The fact remains that Alpinestars has drawn on decades of top-level racing experience to refine even its entry-level models like the S-M3. You’ll definitely feel the benefits. So, don’t be misled by its seemingly straightforward design.
For the S-M3, Alpinestars implemented a new internal testing standard, evaluating the chin bar under heavier impact loads than required by certification norms. Both the shell thickness and structural design of the motorcycle helmet were optimised to make the chin piece extra solid and more impact-resistant. The patented sun peak release system ensures that the sun peak detaches automatically when a specific force threshold is reached, effectively reducing and managing the forces transmitted to the motorcycle rider’s neck during an impact; a kind of crumple zone for motorcycle helmets.
The comfortable liner is made from recycled materials to reduce the environmental footprint. The fit can be adjusted to match the motorcycle rider’s head. The crown and cheek pads of this motorcycle helmet are available as OEM replacement parts in various thicknesses. They are easy to remove, and thanks to an emergency-release system, the motorcycle helmet itself can be safely taken off if needed.
The soft chin strap is 25 mm wide and made from durable textile material. The Double D-ring closure remains the go-to fastening system for both safety and precision fit.
The S-M3 motorcycle helmet meets the latest ECE 22.06 homologation standard. This is a very cost-efficient motocross helmet that raises the bar higher than you’d expect at first glance.
For maintenance of this helmet we recommend S100 helmet and visor cleaner for the outside. For cleaning the interior, without removing it, you can use S100 helmet interior cleaner. New visors have received a water-repellent treatment.
