Q. Why is an off-road helmet different?

Answer

When off-road racing moved to full-face helmets from 3/4 helmets, the nose guard and mouth guard became an integral part of the full-face helmet. This is the reason why the nose piece and mouthpiece are so much bigger. During a strenuous race, the guard is also well-ventilated, which makes it simpler to take deep breaths. In addition to this, this can prevent goggles or face shields from fogging up. Helmets designed for motocross are purpose-built for the activity and have ventilation rather than a sealed system. They also offer protection from rocks, dirt, and other hazards that can be found in natural settings. Helmets designed for motocross riders tend to be slightly thicker than those designed for street motorcyclists because of the additional protection they offer.
