- The new Arai GP-5k helmet is largely based
on its big brother, the GP-5, while offering a
more affordable alternative for drivers not
wanting all the features of the more expensive
GP-5. The Arai GP-5k is heavily favored by
sedan or rally drivers, who do not require all
the upper ventilation found on the GP-5 while
at the same time appreciate the slightly
larger eye port opening (Approximately 10mm -
5mm up and 5mm down).
- Constructed of Arai's exclusive clc (Complex
Laminate Construction) shell technology, which
is less costly and slightly heavier than our
lightest Sclc material, allowing for a lower
retail cost, while still providing the same
level of impact energy management.
- The interior remains very similar to the
previous GP-4 series, with the addition of
approximately 5mm more room in the facial area
and slightly more forehead room. Arai's GP
series' utilize a proprietary flame-retardant
interior material known as Lastan™
- The chin bar area has been modified to
incorporate 2 air intake slots, which have
been moved up just under the shield. The now
solid chin bar has some subtle details in the
mold and has been extended down slightly,
giving the appearance of a much more robust
- The Arai GP-5K helmet shield is slightly
different in shape and size as compared to the
previous GP-4 design, with weight reduction in
mind. The Arai GP-5K helmet shield mounting
hardware is also different from the GP-4.
- Upper ventilation is comprised of a single
intake and single exhaust duct.
- The interior fit is typical Arai, benefiting
from years of research and refinement,
resulting in a helmet that more closely
matches the shape of the human head. Such a
close fit allows for the smallest possible
helmet to be worn, while still being
comfortable. Often times a poor fitting helmet
results in the use of a helmet that is a full
size too large in an effort to avoid painful
- Combined with incredible fit and comfort,
Arai concentrates on balance and center of
gravity. All too often, people concentrate
more on the weight of a helmet instead of how
that weight is distributed over the entire
helmet, how much of the weight is carried down
low and most importantly how that weight is
transferred to your head.
- A properly fitted helmet will distribute the
weight of the helmet more evenly over and
around your head, making the helmet seem
lighter than it actually is.
- A helmet that is more evenly balanced and
carries more of its weight down low will also
appear to be lighter and cause less fatigue.
- The Arai GP-5K helmet is another representation of Arai's pursuit of a comprehensive package, providing comfort, function in an attractive package, masking the hidden energy management system within, with some affordability kept in mind. Because after all, the thing to remember is that a helmet is worn to take the abuse in the event of an impact and if necessary be destroyed in that process.
