"While picking up my 1200RT today as part of the customer brief I was told to put the bike to "sleep " each time I park it. This means applying the steering lock which apparently puts the Canbus into dormant mode otherwise it keeps checking itself despite showing no display. During the winter there were several cases of GSs suffering from flat batteries just sitting in the garage and some owners being stranded................Well that seems to be BMWs answer to the battery drain issue..............Believe it if you wish can't do any harm IMHO to give it a go."
