Product Details

Features

  • Varied thickness shell construction for optimized protection and light weight
  • Optimized for MX, Enduro, and Offroad use
  • Delivers blend of performance, protection, and comfort
  • Key Features
  • Features thermo-injected shell incorporating a polymer blend enhanced by varying degrees of thickness that is engineered to deliver the optimal combination of impact protection and light weight
  • Lightweight outer shell is constructed from impact resistant thermoplastic
  • Inner shell constructed with a composite fiber assembled between the outer shell and the EPS liner for maximum protection against impacts
  • Fit can be tailored to the rider's head thanks to the helmet's crown and cheek pads
  • Construction
  • Multiple density inner liner ensures the helmet is equipped with the correct density in the correct area for enhanced impact absorption, while also helping to reduce overall weight
  • 6-piece EPS liner with three different densities
  • Polished inner EPS liner with special coating to reduce friction with comfort liner for rotational impact management
  • The inner and outer surfaces are engineered to minimize the effects of oblique impacts
  • Low friction coating is applied to the inner part of the main EPS liner to reduce the rotational acceleration forces that can result form certain oblique impacts
  • Maximized ventilation and high levels of heat transfer exchange thanks to ten inlets and seven exhaust ports
  • The visor has been designed to direct air into the ports for enhanced airflow
  • Visor release system ensures the visor is released with the correct pre-determined amount of force, effectively reducing the forces on the rider's neck during an impact
