Alpinestars S-r10 Arius Helmet

The Alpinestars S-R10 Arius Helmet is the culmination of over 10 years of intensive development and testing to create the most advanced protective headgear for racers. This performance-driven helmet features a carbon shell construction and advanced aerodynamics to provide riders with a new level of safety and stability. Engineered with input from MotoGP legends, the S-R10 delivers a perfect blend of ventilation, comfort, and lightweight performance.

• Shell & Impact Protection:
  • Advanced molding technology uses a multi-composite combination for high-density strength
  • Unique shell construction provides effective protection against linear and oblique impacts
  • Low-friction surface on the inner EPS liner helps mitigate rotational acceleration
  • Elastic joints on the rear spoiler allow detachment during impact to reduce rotational energy
• Fit & Comfort:
  • A-Head Fitment System allows height and angle adjustment for a custom fit
  • Removable and washable linings with anti-microbial treatment for long-term freshness
  • Hydration system channel integrated into the cheek pads
  • Emergency extraction system on cheek pads for safe medical removal
• Aerodynamics & Ventilation:
  • Aerodynamic shape developed using CFD simulations to reduce drag and enhance high-speed stability
  • Eleven ventilation points integrated with internal air ducts for active airflow circulation
  • Large central top slider channels air for improved cooling and heat extraction
  • Chin vents create laminated airflow to effectively reduce shield fogging
• Shield System:
  • Metal locking mechanism helps prevent shield detachment during impacts
  • Tool-less quick-release system for easy visor removal or replacement
