Snug fit. With time, the cheek pads will squeeze and adapt to the face of the rider. If you like a more roomy fit, we recommend to size up.
 
Description
The result of over 10 years of intensive study, development, and testing, the goal of the Supertech family of helmets is to create the most advanced, protective, and performance-enhancing helmets possible for racers and riders worldwide. Following years of extensive research, development, and testing of the Supertech R10 road racing helmet by Alpinestars’ Helmet Product Development Department, together with MotoGP legend Andrea Dovizioso, and MotoGP riders’ Jorge Martin, and Jack Miller. With the S-R10, the focus of the design was to ensure the highest level of performance, especially when it comes to protection and a new level of safety. The S-R10 Helmet has been engineered to provide the perfect blend of excellent ventilation, unsurpassed comfort, and the lightest weight possible without compromising on any other front. Another crucial element unique to the S-R10’s design and development is the helmet’s advanced aerodynamics, with countless sessions in the wind tunnel aimed at reducing drag and providing optimal aerodynamic stability.

A-HEAD FITMENT SYSTEM
Adding to the personalization and custom, tailor-made fit of the S-R10, is the helmet’s unique and patented A-Head Fitment System. The A-Head System allows the helmet to be tuned exactly to the rider’s preference by having the ability to adjust both the height and angle at which the helmet sits on the head. The EPS is fitted with the A-Head Fitment System that allows for an ultra-specific setup that can be adapted to how deep the rider’s head sits in the helmet, as well as how far forward or backward the helmet is tilted.
 
AERODYNAMICS
Developed with CFD simulations, validated in the wind tunnel and on track, the S-R10 helmet is optimized for low drag performance and maximum aerodynamic stability.
 
The S-R10 has been developed in the full-scale wind tunnel since the beginning of its development. Aerodynamic targets for coefficient of drag in different head positions, as well as stability at different angles were a primary goal in the helmet shape development, first extensively developed with Computational Fluid Dynamics, then validated in the full-scale wind tunnel and finally on track. The result is a helmet that achieves the lowest level of drag, and the highest level of aerodynamic stability at high speed compared to any other race helmet we have tested in the wind gallery. This has made the S-R10 already the helmet of choice by factory MotoGP teams for its top aero performance. The road riders will benefit from this too, with reduced strain on their neck at high speed and low levels of wind noise.
 
The S-R10 Solid Helmet comes with the Road aerodynamic spoiler – and a longer race version is available as an option – and they’re both fitted with an Alpinestars patented release system, with elastic joints that help the spoiler detach from the helmet shell if it is subjected to a significant impact, no matter the angle, to reduce potential rotational energy.
 
There are also lateral winglets to further support the S-R10’s stability and improve aerodynamic drag. In addition, the helmet visor has turbulators to improve aero-acoustic performance. As a result, compared to the aerodynamic performance of the helmet fitted with the standard road spoiler, the S-R10 itself is already the top performing aerodynamic helmet we have tested, and with the configuration of the race spoiler and the aero winglets together, we have achieved a reduction in drag by an additional 4.54%.
 
VENTILATION
The Supertech R10 helmet contains eleven ventilation points.
 
When it comes to ventilation and breathability, there are 11 ventilation ports, not including the eye port, with 7 intakes including 3 in the chinguard and 4 on the top of the helmet, plus 4 exhausts, with 2 lateral ports on the chin bar, and 2 on the top rear of the helmet. These ventilation ports integrate directly with the helmet’s shell with a series of air ducts through the inner EPS liner. With the S-R10, airflow comes in through the ports, as well as actively circulates over and around the rider’s head through a series of channels and then gets extracted out the back of the helmet.
 
The top vent features a large central slider which channels air down to the top of the head for better comfort, which when open, has vents for hot air extraction from the rider’s forehead. Under the rear spoiler there are two extractor vents for effective hot air exhausting. The chin vents are formed by two openings located at the front of the helmet at the sides of the shield lock mechanism, where each flap has a tab in the corner, which is used to open or close the vent. Air entering from this point is channeled towards the inner side of the shields, creating a laminated flow of air that effectively prevents fogging and misting. And additionally, the chin bar vents are used to extract humid air to the outside of the helmet.
 
SHIELD FEATURES
The shield mechanism is fitted with metal lock components to prevent unwanted shield detachment during impacts, locked in the closed position by a front metal lock.
 
The visor has two unique features including a metal locking mechanism lever to prevent unwanted shield detachment during impacts and/or crashes, plus a lowered side line for a maximized field of view, coming on top of an already outstanding wide eyeport providing 220-degrees of lateral and 57-degrees of vertical visibility for great riding comfort.
 
The shield attaches to the shell via side cams mechanisms, allowing the shield to rotate and to move, in order to seal it completely against the helmet’s rubber window trim.
 
Additionally, the visor itself can be easily changed or removed thanks to its secure and tool-less quick-release system.
 
The S-R10 is fitted with an Optical Class 1 shield, 3mm in thickness, and coated with an anti-scratch and anti-fog treatment.
 
The shield is equipped with internal pins to accommodate a PINLOCK 120XLT - 100% MAX VISION lens and external pins to accommodate tear-offs.
 
2 shields included: 1 clear and 1 dark
 
REMOVABLE LINING
Linings are removable and washable, and feature fabrics with anti-microbial treatment.
 
Crown Pad: The crown pad and the neck pad are elastically connected, for enhanced oblique impact management, with a construction based on four panels (front, sides, rear), for an optimized fit with the proper foam thickness.
 
Top Pad: The top pad is removable and height adjustable via the A-Head Fitment System.
 
Cheek Pads: The cheek pads are fitted with premium foam and fabrics, offering comfort and breathability. The cheek pads also feature an emergency extraction system, allowing the side cheek padding to be easily removed by trackside support and medical staff, and they also have a channel for the installation of a hydration system.
