Arai VX-Pro4 Block Helmet, Black Frost | Off-Road and Adventure Riders

Size: Medium

Top-Tier Protection from One of the Most Trusted Names in Helmets

If you ride moto, your helmet is not the place to cut corners. Your head and brain are the most important things you bring to every ride, and the Arai VX-Pro4 is one of the best off-road helmets you can put between them and the ground.

Arai is one of the most tried-and-true names in motorcycle helmets, backed by decades of experience and a design philosophy focused on protection instead of gimmicks. This is the helmet we personally recommend for riders who want top-level construction, comfort, and attention to detail. It is a premium investment, but when it comes to protecting your head, we believe it is worth every penny.

The VX-Pro4 Block combines a lightweight design of approximately 80 ounces with advanced shell materials and impact-conscious exterior components. Its intermediate oval interior shape is designed to fit many head shapes commonly found in the North American market.

The shell combines Super Fiber with Arai's Peripherally Belted Complex Laminate Construction, also known as PB-CLC. Super Fiber provides 30% greater tensile strength than standard fiberglass, contributing to increased penetration resistance and overall durability. The PB-CLC shell is engineered to provide impact protection while maintaining shell strength and integrity.

Arai's smooth, consistently rounded shell follows the Glancing Off design concept. The compact, rounded chin bar and breakaway exterior components are designed to reduce snagging, digging, and the transfer of excessive energy during a fall.
