Key-On can only occur in the presence of one of the
two keys (3) or (4) or using the pin code. Key-Off can
also occur without any key (3) or (4). Key-Off occurs
when the speed of the motorcycle is equal to zero,
by pressing button (6) on the handlebar or by pressing
the Hands free button (7). When speed is not equal
to zero, perform key-off by pressing the Hands free
button (7).
The mechanical part (A) of the key (3) is used to open
the fuel filler cap, the seat latch and bag locks. The
metal part (A) of the key (3) remains hidden inside its
housing, you can take it out by pressing button (B).
Note
With the vehicle in "Key-On" and "engine off"
condition, if the presence of the active key (3) is not
detected for thirty consecutive seconds, the
motorcycle will turn off automatically without any
action by the rider.
