Alpinestars Supertech R10 Martinator LE Helmet Blue/Purple/Red. The Supertech R10 results from over 10 years of study in developing Alpinestars' first full-face road helmet for MotoGP riders. It features ultralight materials, an aerodynamic profile with a rear spoiler, a high-performance ventilation system, and comfortable internal padding for all bikers on track or road.

The ultra-light outer shell, made of 3K carbon fibre, provides resistance and protection while ensuring excellent aerodynamics and stability, thanks to its design and rear spoiler. The EPS multi-density foam absorbs high-impact forces and reduces rotational acceleration. A wide visor allows for an extensive field of vision, up to 220º, and is compatible with Pinlock® and Tear-off sheets. The ventilation system with 11 airports ensures effective airflow and heat evacuation. Inner comfort pads feature antibacterial treatment and are washable. It includes the ERS emergency removal system and a double metal buckle closure, with provisions for a hydration system installation.

SHELL

• External shell manufactured with advanced multilayer moulding technology with 3K carbon fibre, aramid fibre, and high-density glass fibre that offer excellent lightness and maximum impact protection.
• 4 ergonomic shell sizes for a better fit in each size.
• The EPS foam inner shell of different densities is designed to absorb strong impacts and reduce rotational acceleration thanks to the patented system.
• A-Head system developed by Alpinestars, by which a correct height and angle adjustment is provided for the helmet to fit perfectly to the head position in any driving position.

SCREEN

• Wide high-clarity display with class 1 optical level that offers up to 220° side vision and 57° vertical vision to ensure maximum vision in any driving position. The 1.6mm thick screen on the sides and up to 2.6mm in the central area has anti-ray and antivaho treatment.
• It includes a metal locking mechanism on the side and a metal locking in the area of the chin to prevent the screen from detaching during an impact.
• Predisposition for Pinlock® 120XLT 100% Max VisionTM (including).
• Predisposition for the installation of Tear-Off (included).
• The fast-release system through which the visor can be removed without the need for tools.
• Includes transparent and dark smoked screen.
• Available spare screens: smoked, mirror silver, and photochromatic (sold separately).

AERODYNAMICS

• Shell and spoiler designed under extensive wind tunnel testing to provide the maximum aerodynamic coefficient and stability at different driving angles and high speeds.
• The S-R10 allows the installation of 2 interchangeable rear spoilers. One standard version (including) and one with a longer profile for racing and high performance (not included).
• Patented system for the release of the rear spoiler using elastic joints that help to get rid of the helmet in case of fall and thus reduce the impact force.
• Side fins provide greater support and stability for the helmet as well as improve aerodynamic resistance.
• Helmet screens feature turbulators to improve aeroacoustic performance to reduce wind and noise resistance.
• The configuration with the alloy of racing and aerodynamic spoilers reduces the resistance by up to 4.54%.

VENTILATION SYSTEM

• Very effective ventilation system consisting of 11 vent ports strategically located with 7 air inputs and 4 extractors for excellent air distribution and heat evacuation.
• Upper ventilation: entering of central ventilation located at the top of the limelet and channelling the air for greater comfort and airing.
• Ventilation in the area of the chin: formed by two openings located in the front of the hull, which can be regulated by a tab. The air that enters this port is channelled into the interior, creating a laminated airflow that prevents the tarp.
• Ventilations in the chin: extract the wet and hot air to the outside of the hull.
• Rear Air Extractors: two extractors on the back for excellent hot air evacuation.

PADDED INTERIOR

• Indoor paddingis made with premium material and antibacterial tissue, completely dismountable and washable.
• Adjustable superior pad thanks to the A-Head system for greater comfort and safety.
• Mesh pads made of 3D laminated foam, with a predisposition to install a hydration system (not included) and an ERS emergency release system that allows a correct and safe removal of the helmet in case of an accident.
• Pad in the chin area that allows proper protection against the side air entrance.
• Pads in the ear area for greater comfort as they reduce noise inside the helmet.
• Air deflector for increased noise reduction and improved aerodynamics.
• Breath deflector that prevents misting.

OTHER

• Optimized chin bar design for maximum protection of the collarbone. The lower profile features softer EPP coating material (expanded polypropylene) that extends beyond the helmet's housing and is covered by a more flexible rubber compound. This design provides a reduction in the likelihood of any type of lesion in the collarbone, one of the most common motorcycle injuries.
• Zip by double metal buckle with 25mm strap made of high-resistance nylon.
• Predisposition for a hydration system (not included).
• Includes standard spoiler.
• Includes transport bag.
• Approximate weight: XS/S: 1,490 gr. Δ M: 1,540 gr. Δ L: 1,590 gr. Δ XL/XXL: 1,645 gr.
• Homologation for ECE 22-06, DOT and FIM standards.
