Never thought I'd start a thread in this section, as I own one of those super-reliable 2005 1150s. Well it was super reliable till this morning. 
Wheeled her out of the shed, Got kitted up for my Fathers Day blast around West Wales and ..... nothing. I suspect the battery is flat, but I find it strange that it is totally lifeless today, but we took it out for a 300 mile blat over 2 days just last weekend and it was fine then.
There is no alarm on the bike and the keys was removed when I parked her up last Sunday (so there was nothing draining the battery) but the clock just shows 0.00 (again this was working fine last Sunday) there is no re-assuring clicking etc as you turn on the ignition (although there is a very very faint flicker from the neutral light) and the fuel indicator is lifeless.
I did have problems starting the bike about 2 months ago, and bought an Optimate which cured it. These days I normally connect the Optimate after every trip, but typically I didn't do it last Sunday. Nothing has been changed on the bike apart from having a Stebel Magnum horn fitted 3 weeks ago.
I have connected the Optimate for about 30 mins now, which shows a weak battery, but at least now there is a noise (like an asthmatic wet fart) and the fuel indicator works.
So I'm sat at home wreaking of Ewan McGregor aftershave (Fathers Day present from the wife and kids)
and feck all to do apart from some ironing and work stuff.
Is it common for a battery to die so suddenly?

After an hour on the Optimate, the Neutral light is stronger and there is now a clicking and whirring noise from the petrol pump.
