Arai Vector-2 Diamond White Motorcycle Helmet

Arai Vector-2 Diamond White Motorcycle Helmet

The Arai Vector-2 in Diamond White is a plain gloss white with no graphic, so the shell shape carries the whole look. The ACF-2 front intake with its sliding closure, the ACR-2 rear exhaust and wing, the larger side exhaust ports and the wide eye port all read cleanly against the white. Brand new and never worn (vintage new old stock), this helmet comes exactly as received, fully preserved in its original packaging with all included accessories.

The Vector-2 is Arai's less-is-more full-face, delivering the core Arai construction without the flagship's feature count. It carries the same wide peripheral field of view as the Corsair-V, a cLc (Complex Laminate Construction) shell with Arai's Hyper-Ridge reinforcement band, and the Super AdSis LRS tool-free shield system. The ACF-2 front intake adds a sliding door that closes both the vent opening and the hole in the shell, and the ACR-2 rear exhaust and wing accelerates air over three 10mm shell holes from a single slider. The fully removable, washable liner comes in optional sizes to micro-fit, with emergency-release cheek pads. Intermediate Oval fit, DOT and Snell M2010 certified, made in Japan. Note: Snell M2010 has been superseded by newer Snell standards; this helmet carries the certification current at the time it was built.

Specs & Features

Shell & Safety Design

  • cLc (Complex Laminate Construction) shell: reinforcement felt layer sandwiched between laminate layers for added strength without heavy weight.
  • Organic shell shape design philosophy (smooth, round/egg-inspired profile to help manage real-world impact forces).
  • Multi-Density single-piece EPS liner (up to 5 densities in some models) for impact energy management while keeping size/weight down.
  • Hyper-Ridge reinforcing band around the base to add strength and lower center of gravity (lighter feel, less fatigue).

Fit Shape & Sizing Notes

  • Interior fit shape: Intermediate Oval (I/O) for the Vector series. Helmets sizing
  • Micro-fit features (built in):

    5mm Peel-Away Cheekpad Layer (fine-tune cheek fit without buying different pads).

    5mm Peel-Away Temple Pad Layer (Vector-2 specific extra tuning for temple/side pressure).

  • Vector-2 liner + cheek pads are exclusive to this model (not interchangeable with other Arai models).

Shield System & Visibility

  • SAI faceshield system with a wider field of view:

    Shield is 5mm longer on each side + 5mm wider eyeport each side = noticeably increased peripheral vision.

  • Optional SAI Max Vision anti-fog shield + Pinlock-ready cavity and optional Pinlock insert

Ventilation & Aerodynamics

  • ACR-2 rear exhaust vent/wing combo (wind-tunnel tuned; accelerates airflow over shell exhaust holes for improved heat removal).
  • ACF-2 front intake vent with a sliding door designed to close the intake opening more completely when shut (including the shell opening).
  • Pull-Down Airflow Spoilers to reduce wind noise and help extract hot air from the face area.

Comfort & Removability

  • Fully removable liner with a full-perimeter crown pad design for comfort (and washable/replaceable liner concept).
  • Removable/replaceable cheek pads with removable/washable covers.

Practical Notes

  • Vector/Vector-2 cheek pad install/removal is opposite of other Arai cheek pad types (worth noting for customers doing first-time removal).
