How Tight Should Motorcycle Helmet Be?

Hey, did you know that wearing a bike helmet lowers the risk of head injuries by 45%, brain injuries by 33%, facial fractures by 27%, and life-threatening injuries by 29%? Consequently, wearing a helmet that is the proper size protects your head and brain, reducing both internal and external pain. But How Tight Should Motorcycle Helmet Be?

The answer, then, is to purchase a helmet that has chipmunk cheeks and shouldn’t put any pressure anywhere on the head. To the point that it is bothersome to chew gum in, it should fit snugly. Besides, face, neck, and chin strain will occur when wearing too tight headgear. So, fitting snugly should be the first priority.

In general, a person’s head shape, size, and preference determine the appropriate helmet size. However, check out our guidelines below to pick the perfect fitting helmet for safety.

Types of Motorcycle Helmets

Okay, to start by sharing the proper size of helmets, let us introduce some types of bikes. Three different styles of helmets are typically seen: full-face, half-face, modular, or off-road headgear.

The bikers also use open-face and ADV dual-sport helmets as well. These helmets are frequently worn by riders on cruisers, retros, and classic motorcycles. Let’s introduce them a little.

Full-face helmets offer the most protection and come with extra security features like a locking face shield mechanism and strengthened chin bars to defend against impact during a crash. The helmet provides maximum protection and is also environmentally sustainable. But in warm weather, it might be claustrophobic and uncomfortable.

Due to the lack of a chin bar and the fact that they only cover your head from the top of your brows to the top of your hair, half-face motorcycle helmets, also known as “beanie” or “shorty” helmets, are lighter and more comfortable than full-face models. These helmets are good for warm environments.

Another type of helmet is modular, which quickly changes from a full-face shield into an open-face helmet when the rider presses a button. Modular helmets use a flexible mechanism to swing the chin bar and face shield. Actually, half-shell headgear often provides less overall protection than modular helmets.

The three-quarter or open-face helmet is another type of headgear that lacks a chin guard but completely encloses your head from the eyebrows up. It is the only free helmet available but provides the least amount of safety. In order to prevent head twisting inside the helmet, it should fit snugly against the head.

ADV dual-sport helmets combine open-face ventilation and a broad field of view with full protection. You can effortlessly flip up the visor to communicate with someone or to get some water without taking off your entire helmet. Beneficial, right? Yes, it is!
