Designed To Perform & Protect

Optimized chin bar design
for maximum collar bone protection. In addition to the aero and drag performance optimized shell, it is also designed with a recess at the collar bone area to keep a softer volume in case of contact with the body. The chin bar is profiled for light weight and robustness, protecting the rider’s chin tip area.

Fully Optimized Aerodynamic Shape

Overall helmet shape developed for aerodynamic efficiency and stability.

Race spoiler and winglets further reduce drag by 4.54%

Wing & Spoiler

An aerodynamic spoiler is fitted with a patented release system, also utilized on the visor of the Alpinestars S-M10 motocross helmet, with elastic joints that help the spoiler to detach from the helmet shell if it is subjected to a significant impact, no matter what the angle. (2 spoilers available: Standard and Race - with a more drastic aero effect)

The Lateral winglets support the stability and improves the aerodynamic drag.

The S-R10 helmet is fitted with turbulators on the visor to improve the aero-acoustic performance.

Shield Features

The shield mechanism is fitted with metal lock levers to prevent unwanted shield detachment during impacts, that are locked in the closed position by a front metal hook. The cinematic movement is engineered to perfectly seal the visor against the shell’s rubber window trim, while staying distant from the shell in the opening phase. The tool-less quick release system allows fast and easy change of the visor.

11 Ventilation Ports

Chin Vent
The chin vent is formed by two openings located in the front of the helmet at each sides of the shield lock mechanism. Each flap has a tab in the corner, which is used to open or close the vent. Air entering from this point will be channeled towards the inner side of the shield, creating a laminated flow of air that effectively prevents fogging and misting.

Chin Bar Vents
These are used to extract humid air to the outside of the helmet.

Top Vent
The large central slider channels air down to the top of the head for better comfort. This in turn, when open, has vents for hot air extraction from the riders’ forehead.

Rear Spoiler
Under the rear spoiler, two extractor vents are located for effective hot air extraction.

A Head

The EPS is fitted with the patented A-Head fitting height and angle adjustment system; developed by Alpinestars and originally utilized with great success in the S-M10 Motocross helmet, to allow the product to be tuned exactly to the riders’ preference for the height and angle at which the helmet sits on the head.
