Motorbike helmets (Whitnash CV31)

Not sure if anyone can repurpose 2 motorbike Helmets. 1 has been used the other , ehich is the black one. has never been worn. Both over 5 years old so cannot testify to their effectiveness as recommended that they are replaced after 5 years. Neither have been involved in a crash. But may be handy to someone before I begrudgingly put them into land fill.
