The Alpinestars Supertech R10 Helmet combines advanced composite construction, race-developed aerodynamics, and a precision-focused fit system for demanding motorcycle riders. This Arius edition features a gloss black, silver, and yellow fluo finish with a 2XL fit. Part number 8203926-1699-2XL identifies this premium full-face helmet, engineered to provide effective energy management while maintaining a lightweight, performance-oriented design. The outer shell uses a multi-composite construction with a 3K high-density carbon outer layer, unidirectional carbon composite, aramid fiber, and fiberglass bonded with pre-preg epoxy resin. This carefully controlled fiber-to-resin ratio helps maximize strength, mechanical performance, and impact energy dissipation while limiting shell deflection.
Features:
- Outer Shell: Multi-composite construction combines 3K high-density carbon, unidirectional carbon composite, aramid fiber, and fiberglass for strength, efficiency, and controlled energy management.
- Inner Shell: Four optimized inner shell sizes help improve fit, comfort, impact performance, and overall weight distribution.
- EPS Liner: Eight-piece, multi-density EPS construction uses six strategically positioned densities to absorb impact forces and provide a close, comfortable fit.
- Impact Management: A smooth, specially coated low-friction EPS surface helps manage linear and oblique forces by allowing the comfort liner and rider’s head to move more independently within the helmet.
- A-Head Fitment System: Adjustable height and angle settings allow the helmet position to be tuned to the rider’s head shape and preferred riding position.
- Aerodynamics: CFD simulations, wind-tunnel testing, and track validation support low-drag performance and aerodynamic stability.
- Lateral Stability: Integrated winglets help improve stability and aerodynamic efficiency at speed.
- Visor Aerodynamics: Visor turbulators are designed to improve aero-acoustic performance.
- Ventilation: Eleven ventilation points, excluding the eye port, include seven intakes and four exhausts for continuous airflow.
- Airflow Management: Integrated shell ducts circulate air around the rider’s head before directing hot air out through the rear exhaust ports.
- Top Vent: A large central slider channels fresh air toward the crown and opens additional passages to help remove heat from the forehead.
- Chin Ventilation: Adjustable chin openings direct air toward the shield to help prevent fogging while also extracting humid air from inside the helmet.
- Finish and Fit: Arius graphics in gloss black, silver, and yellow fluo with a 2XL size configuration.
