For maximum safety, SPEEDJET must fit tightly and be correctly
and securely fastened, so it cannot be taken off neither by pulling
it nor by rotating it around the head (see figure 1). If it is too big it
may slide down over the eyes or turn in a lateral direction due to
movement during riding, thus blocking visibility.
FIGURE 1
Do not use scarves or neck guards which could make the strap
slide and the helmet fly off in case of crash.
SPEEDJET was designed to be used with most of the eyeglasses on
the market. In any case check how the helmet fits with the glasses
before purchasing it.
The function of the helmet is to reduce stress on the user's head
in case of crash; this happens through a partial destruction and/or
deformation of its components (mostly the external shell and the
internal polystyrene shell). In this way part of the energy generated
by the impact is absorbed by the components of the helmet, thus
reducing the vibrations on the user's head, eliminating or limiting
the risk of traumas. The protection capacity of the helmet is not
endless and certain crashes may generate such high stress that
even the energy absorbed by the helmet is not enough to protect
the user from injuries: no helmet, even top quality helmets, can
