  • For maximum performance the shell is assembled from multiple proprietary components
  • Super fiber, one of the primary materials costs up to six times more than standard fiberglass, but provides 30% higher tensile strength and increased penetration resistance
  • The complex laminate construction method demands precise and time consuming assembly by master craftsmen from many individual pieces and exemplifies the experience and dedication of the Arai family
  • Ventilation consists of additional top vent hole, increasing from five to six upper vents
  • The air through construction of the top front vent and top rear vent covers as well as the side port air ducts are designed to offer greatly improved ventilation efficiency and are easier to clean and maintain compared to previous models
  • The upper and lower rear exhaust vent cowl is designed to increase airflow and vacuum exhaust
  • Vent design still fragile under crash impact, but is more durable against smaller contact
  • Upper rear exhaust vent set design to accommodate all five shell sizes
  • The shell itself is consistently round and smooth, maintaining the R75 shape concept in areas above the acknowledged test line
  • The intermediate oval shell shape is designed for the rider whose head has a front to back dimension that is longer than the side to side dimension
  • The rounded chin bar maintains the same compact shell length with the previous model, the VX-Pro 3 but results in less protrusion, which has proven to be less likely to catch and dig in during a spill
  • Chin vent incorporates expanded stainless steel mesh moved from inside to outside of shell, provides room to move the EPS (Expanded Polystyrene) chin liner forward for more room in the face area
  • Stainless mesh grill can be easily removed for cleaning or damage replacement
  • Chin vent mesh cap is easily removable with single screw and will break away if necessary in an impact
  • Three basic chin intakes, two under peak intakes, six upper exhaust and two lower exhaust
  • Inner mud gate that can be easily removed for more airflow
  • To compensate for increased lift, the air outlets on the peak have been made larger
  • The VX-Pro 4's peak is 14mm longer, 5mm wider than VX-pro 3 for improved ability to deflect roost and flying debris
  • Liner components feature FCS (Facial Contour Support) cheek pads that have a larger surface area, wrapping under jaw for more comfort like Arai street helmets
  • Emergency cheek pad removal strap label design for easier use, label acts as pull tab for strap
  • The top rear duct center brace, together with the side port cowlings, also assist in keeping the strap in position on the side back areas
  • Removable, replaceable, washable neck roll pad
  • 5mm peel away cheek and temple pads
  • Vents designed to assist holding goggle strap in center position and not slide off, up or down
  • Eye port has molded rubber trim across top, with standoff ribs, that resist goggles wearing the helmet liner as well as providing small gap for airflow
  • The goggle strap locator's keep the goggle strap in position even during aggressive, competitive riding
  • Meets or exceeds SNELL and DOT certifications

General Sizing Information

If you are unsure about your size, compare your body measurements to the charts provided to determine the correct fit. These charts will give you a good idea of the size to order, but be sure to read special sizing information that may accompany an item description. Some merchandise dimensions may vary from the averages charted here.

Head Circumference

Head circumference measurements should be a starting point only in determining your helmet size. Determining the best possible fit should be from actual test fittings of Arai's various interior fit packages, with optional interior lining and cheek pad thicknesses to find the best fit.

Interior Liners and Cheek Pads

Optional interior liners and cheek pads of different thicknesses allow you to custom fit your Arai helmet. When ordering a liner of a different thickness, start with the Lining Code that matches your helmet size, then specify the desired thickness. For example, an optional 5 mm liner for a large helmet would be specified as a "III - 5 mm" liner.
