Arai VX-Pro4 Block Helmet, Black Frost | Off-Road and Motocross Riders
Size: Large
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 comes in the Black Frost finish and uses Arai's intermediate oval interior profile, which is designed to fit many riders 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 traditional fiberglass, contributing to increased durability and penetration resistance. Its smooth, consistently rounded exterior follows Arai's Glancing Off design concept, which is intended to help the helmet redirect energy instead of catching on obstacles during an impact.
A compact, rounded chin bar further reduces protruding surfaces that could snag or dig into the ground during a fall. Breakaway exterior components, emergency-release cheek pads, and impact-conscious mounting hardware complement the strong shell construction.
