Purchasing Guide: The Alpinestars S-M7 Helmet, the smart choice of the high-end without breaking the bank?

Choosing a helmet is one of the most important investments for a pilot. Between entry-level models and technological flagships worth more than €800, there is a highly contested segment: that of accessible premium helmets. This is precisely where the new Alpinestars Supertech M7 (S-M7) is positioned. The successor to the S-M8, he promises to integrate the best of his older brother's technology, the S-M10, at a lower price.

So, successful bet? Is it the helmet with an unbeatable technology/price ratio? Freenduro has compiled all the information to give you a complete analysis.

L’Essentiel at a glance

• Approval: ECE 22.06, the latest and most demanding standard.
• Key security: emergency extraction system (ERS), collarbone protection, multi-technology rotational impact management.
• Shell: Tri-composite (fiberglass, carbon, aramid).
• Weight: approximately 1 360 grams in size M.
• Price: between 400 € and 450 € depending on the color.
• The + that makes the difference: Unique A-Head adjustment system and extensive foam customisation.

Detailed analysis of the Alpinestars S-M7 helmet

1. Design and passive safety: a “smart” shell

The first thing that strikes the S-M7 is its sleek design. Far from being a simple aesthetic choice, its smooth, aerodynamic shape is designed for safety. Alpinestars wanted to eliminate any relief that could act as a “loading point” or hanging when sliding. The curvature of the tri-composite shell promotes the “Deflection” energy and avoids the transmission of brutal forces to the head and cervical organs.

For optimal fit, the range is structured around: 3 sizes of outer shells to cover 6 sizes of helmets (XS to XXL), thus ensuring that you will not have a shell that is too large for your head.

2. Active protection: a technological arsenal at the service of the pilot

It is here that the SM7 impresses the most, complying with the standard ECE 22.06 but going further in terms of safety for the pilot.

Rotational Impact Management

Alpinestars is not satisfied with just one system. The S-M7 combines two mechanisms to dissipate oblique forces, so dangerous for the brain:

1. A glide plane (similar to MIPS) created by a smooth resin on the EPS and a special lining in the cap.
2. A Elastic connection between the main headdress and the neck circumference, providing additional controlled mobility during a shock.

Emergency Extraction System (ERS) and protection of clavicles

Essential today at this level of range, cheek foams can be removed easily by emergency services in the event of an accident, allowing the helmet to be removed safely. In addition, the base of the helmet incorporates the technology “PLASMA”, a flexible foam designed to absorb energy and limit the risk of collarbone fracture.

The programmed ejection visor

The visor is designed to detach automatically in the event of an impact exceeding a force of 15 joules. This prevents it from clinging and causing the head to twist. Its fastening system allows it to be easily reclipsed if it is not damaged.

3. Comfort and tailor-made adjustment

A high-performance helmet is a helmet that is forgotten.

• The A-Head system: This is the Alpinestars signature. This system allows the height and inclination of the inner headdress to be adjusted. This allows you to perfectly adjust the position of the helmet on your head and the angle of your field of vision.
• A customizable fitting: While some returns indicate a somewhat loose initial fitting of the cheeks, Alpinestars has planned the parade: cheek foams are interchangeable between all helmet sizes. So you can buy thicker foams to get a perfect hold.
• Hygiene and maintenance: The interior is fully removable and hand washable. Tissues benefit from antimicrobial treatment to limit odours.

4. The most practical 

• Breakdown: With 13 air inlets and 7 extractors, i.e. 20 orifices in total, the airflow is designed to be efficient even at low speeds.
• Adventure Ready: the S-M7 helmet is really designed for enduro and motocross riders. Channels perfectly guide the hose of a hydration system, and a clever cut in the EPS makes it possible to mount the clamp of a Bluetooth Intercom without having to glue any support on the hull.

Final Verdict Freenduro: Who is the Alpinestars S-M7 helmet for?

The Alpinestars SM7 helmet is clearly aimed at pilots, who are looking for a high-end helmet, but at a more affordable price than the S-M10.  Whether you are a competitor or an intensive hiker, looking for a level of protection validated by the latest standards without wanting to spend the price of a ‘factory’ helmet, this S-M7 is for you.

For Freenduro, this new Alpinestars off-road helmet represents a almost perfect compromise, not sacrificing anything on essential security technologies while offering unique comfort and fit features. If you are looking to scale up and safety is your number one criterion, the SM7 is undoubtedly one of the best investments you can make today.

Good ride and ride carefully!
