A
lpinestars' Supertech
R10 is the result of over a
decade's worth of develop
-
ment, with the finishing touches
coming from MotoGP legend
Andrea Dovizioso before it was
handed to the public. The S-R10
is constructed using a multi-
composite combination featuring
a 3K high-density carbon outer
later, a uni-directional carbon
composite layer, an aramid fiber
layer, a fiberglass one, and it is
homologated to European ECE
22.06 as opposed to the older
DOT standard used in the USA.
The Alpinestars S-R10 shell
was tested over and over at the
company's R&D lab and, accord

ing to the company, far exceed-
ed the standards for ECE 22.06.
According to Alpinestars, the
S-R10 surpassed the standard
for direct linear impacts (where
there is an impact at a 90-de
-
gree angle between the helmet
and an object) by 37 percent. As
for rotational acceleration and
oblique hits, where the impact
energy comes from an angle
other than a linear 90-degree/
right angle, the S-R10 exceeded
the standard by 65 percent.
Much of this has to do with
the way Alpinestars approaches
the touchy topic of rotational
impact absorption. Alpinestars'
method was to create a low-fric
-
tion surface on the inside of the
EPS liner. The inner surface is
polished smooth and coated to
reduce friction, which allows the
comfort liner/padding to slide
against it.
This, Alpinestars says, "[re

with a massive field
of vision, the S-R10
is a winner.
