CE Level 1 Versus CE Level 2 Armour Impact Ratings

Where a lot of riders can get confused is how CE ratings for armour.

Impact armor for use in motorcycle garments must undergo its own set of tests to determine whether it is CE Level 1 or CE Level 2 certified.

CE Level 1 armor has the maximum transmitted force threshold of 35 kN as compared to CE Level 2 with a  higher level of protection in terms of impact absorption and it means the armour has been tested and verified for a maximum transmitted force below 20 kN.
