Why do dirt bike helmets have a peak?

Dirt Bike helmets often have a peak or visor to provide additional protection and functionality for riders. The peak helps to shield the rider's eyes from sun glare, rain, or debris that may be thrown up from the trail. It also helps to improve aerodynamics when riding at higher speeds. Additionally, the peak can provide a bit of shade, reducing the effects of the sun and enhancing visibility. Overall, the peak on a Dirt Bike helmet is a practical and important feature that enhances both safety and comfort for riders.
