The Arai VX-Pro4 Helmet is the perfect choice for MX, enduro and off-road use. Just like all of Arai's helmets, the basic and simple organic shell shape is based on R75 Shape concept. The absence of exaggerated edges or protrusions on the shell is not a lack of creativity, but a commitment to maintaining the integrity of the shell with real world impact performance.

The VX-Pro4 peak is 14mm longer and 5mm wider than the previous model for improved ability to deflect roost and flying debris.
