Opening (fig. 32 and 33)
Fit the ignition key into the lock (1) and turn the key
clockwise until you hear the seat catch click.
Pull the rear end of the seat (2) gently upwards and lift
until clear.
On the front end of the compartment underneath the
seat, there is the helmet fastening cable. Insert the cable
E (A) into the helmet and insert the ends of the cable into
the hook. Leave the helmet hanging outside (fig. 31) and
refit the seat.
Warning
This system is intended to lock your helmet safely
when you park your motorcycle. Never leave the helmet
hanging from the hook when riding or it may get in the
way and make you lose control of the motorcycle.
Inserting the cable under the frame from the left side will
enable to lock the seat.
