Alpinestars S-R10 SIGNED BY PEDRO ACOSTA-LE HELMET-BLACK RED WHITE MATT-SIGNED

SIGNED HELMET

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. 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.

CONSTRUCTION

• The outer shell design protection feature is the chin bar’s profile, where the base area has been specifically sculpted to give a relief section. The bottom profile is raised to clear the collarbone, and instead of the hard carbon shell coming into potential contact with the collarbone, the S-R10 has a softer EPP (expanded Polypropylene) liner which extends beyond the helmet shell itself and is covered by a more flexible rubber compound. This chin bar design provides a reduced chance of any sort of collarbone injury, one of the more common injuries in motorcycling

FEATURES

• Homologated to ECE 22.06, DOT, and FIM standards, the Supertech R10’s shell construction utilizes a highly advanced molding technology with a multi-composite combination featuring a 3K high-density carbon outer later, a uni-directional carbon composite layer, an aramid fiber layer, and a fiberglass one.
• The 3K high density carbon outer layer provides excellent strength and efficiency of energy dissipation over the shell.
• The uni-directional (UD) carbon composite layer provides significantly greater radial strength around the shell, preventing compression, but allowing controlled deflection for reducing transmitted impact energy. And the aramid fiber plus fiberglass layers provide critical penetration protection.
• This layered composite combination created by bonding everything together with an advanced epoxy resin already applied on the pre-preg fiber, perfectly controls the ideal proportion of resin versus fiber to maximize strength, mechanical performance, and lightweight. The combination of material layers provides improved energy management, as well as limited outer shell deflection, making the energy spread wider and better absorbed by the EPS liner.
• The S-R10’s unique shell construction results in extremely effective impact protection.
• The S-R10 has four inner shells just like the outer shell and is available in four anatomical sizes. The S-R10’s construction is optimized to ensure riders have the correct fit, which not only improves comfort and reduces overall weight, but most importantly, improves the effectiveness of the helmet in an impact. Underneath the helmet’s outer shell is an eight-piece multi-density EPS liner, with six specific densities that are strategically positioned in different zones to ensure excellent energy absorption from impact forces dissipated over the outer shell, as well as a close and comfortable fit. The EPS liner, just like the outer shell, has its own unique dimension for each helmet size, further tailoring the helmet’s performance and fit when it comes to protection and comfort.
• The EPS inner surface is smooth, creating an optimized, low friction area, for superior oblique impact management.
  
• To help fight and mitigate those rotational, oblique, and linear impact forces, Alpinestars has designed a low friction surface on the inner surface of the EPS liner.
