For all riders, the helmet is a very private thing and an indispensable part of riding, protecting your head from injury when an accident occurs.

So to wear a helmet for safety, we're actually wearing a bunch of industrial materials, and we use this material to protect our heads.

You see the motorcycle frame material should pay attention to rigidity and torsion effect, right, but the frame is not easy to break, the car can also drive for a long time.

The helmet in the production will use glass fiber, EPS buffer foam, glue, resin, etc., these materials will age with time, will also be damaged by impact.

Therefore, if the helmet has the following conditions, it is recommended to replace:

The helmet took a hit - even the internal EPS buffer foam showed cracks after absorbing the impact.

There are squeeze marks -- you can even see the helmet material.

There are obvious signs of wear and loosening inside - these are mainly oils from hair, body sweat and skin care products, such as sweat salts may powder or harden the EPS buffer foam of the cap body.

Recommended 5 years replacement helmet - even if none of the above phenomena, based on a robust safety concept to prevent potential risks such as material aging, it is recommended to replace the helmet in 5 years.

So try not to drop or break your helmet.

If it is a rub that is still good to solve, belongs to the appearance of the problem, you can find a way to patch paint or stickers.

However, when it comes to the helmet and the EPS buffer foam part, or even the case of visible glass fiber rupture, it is a safety issue, and can only be replaced if the strength cannot be guaranteed.

Now let's talk about the parts of the helmet.

Liner - also called liner, it is recommended to prepare a set, especially in the summer, you can change.

Lenses - large lenses and anti-fog tablets are strictly consumables, affecting the visual effect should be replaced, the use of higher frequency of riders, generally change once a year anti-fog tablets.

Note: The anti-fog sheet itself has a special material, so it can not be washed and chemical cleaners, otherwise it will lose the anti-fog effect, you can use a slightly damp glasses cloth to wipe, other towels are easy to scratch. Large lenses can only be cleaned with clean water.
