How to choose a motorcycle helmet that suits you

Whether the newcomer to the locomotive wants to buy his first helmet, or the veteran wants to replace the old or broken helmet, the most troublesome thing is to make sure that the new helmet to be purchased is suitable for him. In short, this is really not an easy thing. Asians do have a variety of brain types. Their shapes are generally rounder than those of Europeans, the upper part of their head is wider, and the overall face is square. Not to mention that the Chinese have a special tradition that people all over the world don't have: when a child is born, he should sleep on a hard pillow and flat the back of his head. The old people said that the back of the flat head is better looking. It's not clear whether it's really good-looking or not, but it will bring some trouble to choose a helmet. It's true.

Generally speaking, the most important way to choose the size suitable for your helmet is to measure the head circumference. The specific method is also very simple: use a tape measure to circle the widest part of the upper part of the ear and measure the circumference. The specific number of circumference is your head circumference, which is generally measured in centimeters; After obtaining the head circumference, you can determine your helmet size according to the official size chart given by the helmet manufacturer. Take Arai's helmet for example. A helmet of size M is required for a head circumference of 57cm-58cm. It is worth noting that each helmet manufacturer has different size setting standards. Make sure you judge your size according to the size chart of the helmet manufacturer, because there are likely to be differences between manufacturers, resulting in you buying the wrong number. For example, people who usually wear Arai size M may need Suomy size L to be big enough.

However, the accuracy of the size chart is relatively limited. Try on is the most accurate way to judge the helmet suitable for you. The correct way to wear a helmet is to wear it from front to back, rather than rough and random. This is very important and easy to be ignored. If you find that your ears will be folded in the helmet every time you wear the helmet, you must fiddle with your hands before you can unfold your ears, which means that you are wearing the helmet in a wrong way.

The specific operation methods are as follows: first, hold the fixed belts on both sides of the helmet with the thumbs and index fingers of both hands, and cover the helmet shallowly to the upper quarter of the head; Then, the key steps to determine whether you are wearing a helmet correctly appear. Generally speaking, we will continue to pull the strap down until the whole head enters the helmet. This is actually wrong. The correct method is: after the head initially enters the helmet, use both hands to grasp the remaining six fingers except the belt, hold the front jaw of the helmet, and pull down the front of the helmet until the whole helmet is put on. This technique sounds ordinary, but it's absolutely easy to use. Just try it and you'll know; Finally, lock the helmet strap. This is very important. It is as dangerous not to lock the helmet fixing belt as not to wear a helmet. When the car falls, the helmet is likely to fall out of the knight's head and cannot play its due protective role.
