Why are motorcycle helmets so big?

Motorcycle helmets are designed to provide maximum protection for the rider's head in the event of a crash or impact. They are typically larger in size compared to other types of helmets, such as bicycle helmets, due to the added safety features and construction materials used. The larger size allows for thicker padding and multiple layers of impact-absorbing materials, such as expanded polystyrene (EPS) foam, which helps to distribute and absorb the force of an impact. Additionally, Motorcycle helmets often have a hard outer shell made from materials like fiberglass, carbon fiber, or polycarbonate, which provides extra protection against sharp objects or debris. The size and design of Motorcycle helmets also account for additional features, such as a visor or face shield to protect the rider's face from wind, rain, insects, and other potential hazards on the road. Some helmets may also include built-in ventilation systems to keep the rider cool and comfortable during long rides. It's important to note that Motorcycle helmet sizes can vary depending on the brand, model, and specific design. It's essential for riders to choose a helmet that fits properly and snugly to ensure maximum safety and protection.
