Arai VX-Pro4 Block Helmet, Black Frost | Off-Road and Motocross Riders
Size: XS
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 uses an intermediate oval interior shape designed to fit many head shapes commonly found in the North American market. Its compact profile, ventilation system, and removable interior components make it a strong choice for demanding days on the trail or track.
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 durability. The PB-CLC construction helps maintain the strong, consistently rounded shell profile.
Arai's smooth exterior follows the Glancing Off shape concept, which is designed to reduce snagging during a fall. The compact, rounded chin bar further limits protruding surfaces that could catch or dig into the ground. Breakaway exterior parts and emergency-release cheek pads add to the helmet's thoughtful, safety-focused design.
