CHIN STRAP
CHIN STRAP
Depending on the various versions and the
country concerned, your S-DRAK 2 is equipped
with a chin strap with a "Precise Lock" rapid
buckle with a snap lock or one with a double-D
ring. Proper use of the chin strap is critical for
proper performance of the helmet. Never alter
your chin strap in any way. For example, never
cut it or add holes, or apply buttons, studs or
other items to your chin strap. During the life of
your helmet, be sure that the chin strap never
suffers any type of abrasion or cut, and that its
total length does not change. If it does, replace
your helmet.
PRECISE LOCK
The "Precise Lock" snap lock system gives you
precise and accurate adjustment because of the
considerable length of its notched section.
However, it is essential on purchase to adapt
the length of the chin strap to your measure-
ments. Adjust the length of the strap using the
adjusting buckle (figs. A, B, C and D).

Choose your S-DRAK 2 and attach the holding
system. When the "Precise Lock" is adjusted
to the medium position, the chin strap must
be correctly tensioned under the chin to hold
the helmet firmly without causing you any
discomfort or pain.
To fasten the chin strap, all you have to do is to
thread the tongue into its place on the buckle
until tension is perfect (fig. E). The tongue
connects and is automatically blocked.
To release the chin strap, you have to pull on
the lever (fig. F) and remove the tongue from the
buckle. Although the notched tongue enables
you to change the adjustment precisely on each
use, it is important to check frequently that the
adjustment of the strap length is correct.
WARNING! Never ride with the chin strap
loose or insufficiently tightened. Even
though the interior padding gives you the impres-
sion of being held, your helmet risks coming off
in a fall.
Never apply lubricating or acid products or grease
or solvents to the chin strap buckle parts.
