I'm in California USA, and I was crazy enough to read the Owner's Handbook. And it says...
To stop the engine:
▼ Close the throttle completely.
▼ Select neutral.
▼ Place the engine stop switch in the
STOP position.
▼ Turn the master ignition switch to
the OFF position (if equipped).
▼ Select first gear.
▼ Support the motorcycle on a firm,
level surface with the side stand.
▼ Lock the steering.
The Owner's Handbook shows that the "master ignition switch" is the round dial/switch on the left side of the bike.
I usually I turn the "master ignition switch" to off at the end of the day when I'm done riding, and it has never had an ill effect.
Your mileage may vary.
