The helmet may have cracks that will make it structurally unsafe. A dirt bike helmet should be snug around your head. The helmet should not shake or wiggle while riding. Make sure you always strap on your dirt bike helmet securely. Make sure that your helmet fits your head just right. Other things to take into consideration are weight of the dirt bike helmet and air flow. You can measure your head with measuring tape to figure out what size helmet you will need.

If damage has been caused, you want to throw the helmet away and get a new one. These sensors add to your helmets style and will help keep your head much safer.
