“We recommend that
helmets be stored correctly,
away from damp or excessive
heat and kept in their
protective bags after use. We
also recommend that on certain
paint finishes, flies, road grime
and road tar should be washed
off at your earliest opportunity.”
James Egan, Arai UK brand
manager, said: “All Arai
helmets have a seven year
warranty from the date of
manufacture, or five years from
the date of purchase – if a
helmet is three years old when
bought, we will of course cover
it into its eighth year of life on
warranty items, but we would
still recommend replacing it
after seven years anyway.
The main part of the helmet
that warrants it being replaced
is the EPS, which is purely
age-related.
“The EPS (Expanded
PolyStyrene) or Inner Shell is
effectively your shock absorber
– when there is an impact to
the outer shell, it takes and
spreads the initial energy
before it moves to your EPS,
which then dampens that force
before it reaches your head.
“From the time the EPS itself
is produced, it slowly hardens
at a rate of 5% per year,
meaning after seven years you
have lost 35% of your helmet’s
ability to absorb energy in an
impact – this drops it below
Arai in-house standards for
impact absorption, meaning we
regard the helmet as unsafe. It’s
the nature of polystyrene as a
material, so it is applicable to
most helmets.
“We recommend thinking
about a replacement helmet at
five to seven years for weekend
riders, three to five years if you
do regular track riding, and
every year if you’re racing.”
Arai dates its helmets on
the chin strap’s D-ring, either
with a date-stamp showing
MM/YY or a letter code Y/
MM, where A=2001, B=2002
