For friends who love to ride a motorcycle, do they have a certain understanding of their driving equipment? Let's say something about a motorcycle helmet! Motorcycle helmets must be known to all riders and are used to protect their safety. But have you ever cared about your motorcycle helmet? When you use it, can it provide you with security in a dangerous accident?

In fact, motorcycles have a shelf life, and use in this warranty period can give you the greatest traffic safety, and the helmet helmet warranty period is relatively short, only 3 to 5 years, and some riders may wonder why the helmet Will there be a shelf life?

When you wear it for a long time, the outer shell material of the motorcycle helmet will age. However, over time, changes that we can't see with the naked eye will happen.

There are helmets made of composite materials. The older the resin is, the more brittle the impact resistance will be. The breakage of fibers, such as glass fibers and carbon fibers, is also unpredictable. We can't avoid the wind and sun and some slight bumps in our daily use, which will affect the impact resistance and protection of the helmet.

However, the foam inside the motorcycle helmet is also life-spanning, the new helmet foam has more moisture content, and the moisture will be less and less as time goes by, it has an impact on the foam density and shock-absorbing capacity, which makes it easy to embrittle broken. Some people may even say that my helmet was worn for so long and I didn't see any cracks or bad things. The helmet’s aging is reflected in its resistance to falling, abrasion, crush resistance, penetration resistance, etc. Only in accidents can it be reflected. But for our own safety, don't try it lightly.
