I took my bike home from work where I store it during the week on friday. The wife and I went for a ride on Saturday for a few hours and everything was normal. I parked the bike on Saturday night in the garage again and left. This morning I went out to take it out of the garage and she is dead. No lights nothing. I can not imagine that a battery would go dead that quickly. I normally hook up the tneder but did not because I figured she would only sit for the day on Sunday and I would do a little rding on Monday then hook her up to the tender on Monday before I left for a business trip. Everything was off I think. Gps was disconnected and the key was in the locked position. The only thing that is connected directly to the battery is the Autocomm but the helmets were not connected and I have left the bike for 10 days without the battery going dead before. I may have to call the Dealer.

I know you said the key was in "locked", could it have been in "locked, with tail light on"? That could cause a rapid loss of charge.

That would be my suggestion. Even though you had it locked are you sure that you didn't have the parking lights on? I've done that a time or two but I caught it before draining the battery.

I can not say for sure. I thought that at first but not sure. I hvae it hooked up to the tender now and the battery is coming back.
It may be coming back, but you should get a new one anyway. Once any lead-acid battery is drawn down to less than about 1.5 volts per cell (that is 8 volts on a 12 volt battery) it's charge capacity is extremely reduced, and there is no way to reverse the damage.

That's why some of us use the ODYSSEY batteryies. http://www.odysseyfactory.com/

Though still a 'lead acid' type - they're built to better survive deep discharge - not as well as a true deep-cycle/marine type - but well into that direction. Deep discharging one of these will affect it's perforance - but no were near the degree of a traditional lead/acid.

Yea - I've drained mine down to near nothing (left the tracker turned on, again). But, 20 minutes at 10 amps then overnight with a 'smart charger' - she's close enough to %100 I can't tell the diff.
