*ALPINESTARS Supertech R10 Solid Road Helmet
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 personalisation 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 OPTIMISED 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 tunnel. 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 comes with the standard spoiler – and 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 chin guard 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 channelled 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.
