Speed And Strength SS4000 Helmet Sizing
How to Measure a proper helmet
SIZING: To measure your head size, wrap a tape measure horizontally around your forehead. Select the helmet that is the closest fit to that size. A helmet should fit snug on your head. If it moves while wearing, it is too large. If it is painful to wear, it is too small. For proper sizing, your nearest dealer will be able to help you get sized up.
FITTING: Open the chin straps and slide the helmet onto your head starting at the forehead. A helmet should feel snug. If it slides on easily it is too big. It should feel tight to pull down. Make sure the inner padding fits snug all around. You should feel the padding pressing against your cheeks and head. The last check for a proper fit is to test if it moves while wearing, there should be no movement if you shake your head. Place your hands on the helmet and move it front to back and side-to-side. If there is a lot of movement, try a size down.
