Many motorcycle riders are not aware that even a good helmet can be seriously
damaged by being dropped.  For example, dropping a helmet from chest height
onto a concrete sidewalk can result is a hairline crack in the outer shell.
This seriously diminishes the protective ability of the helmet.

Also, a helmet that has been in accident may have hidden damage.  Most
common is crushing of the hard foam padding inside the helmet.  It's this
crushing that provides most of the helmet's protection.  When the foam has
already collapsed, it won't provide protection the next time.

Bell provides an inspection and refurbishing service for their helmets.
