D. THE HELMET
The mechanically optimised system reduces the force need to
operate the two locks to a comfortable 16 N, although the safety-
relevant overall locking force is many times this amount.
Operation
The chin bar can be opened at any time irrespective of the
position of the visor or sun visor. The stiff, positive engagement
at the end of travel ensures the chin bar remains safely in place
when raised.
Opening the chin bar
1. Open the chin bar by sliding the
red button located in the middle
of the chin zone forwards in the
direction of the arrow as far as it
will go, using your thumb.
2. The Bowden cable mechanism will
then release both locks and you
can pivot the chin section up to its
uppermost locking position.

Important:
The C3 Pro's chin bar mechanism is equipped with a safety
feature which prevents the chin bar from opening of its own
accord in the event of a fall, so when opening it you should
also grip the chin bar with one hand.
Closing the chin bar
1. To close the chin bar, pivot it down
with one hand until both locks
audibly engage.
Important:
Each time you close the chin bar, check that the locks have
engaged properly by pressing the chin bar upwards.
Tip:
When using the additional adjustable wind deflector, locking
the chin bar is easier if you grip the chin pad underneath
with a finger of your other hand to help you ease the chin
bar over your chin.
Caution:
Never ride with the chin bar raised!
