Thanks for your thoughts everyone. STella was basically untouched with only a pilfering of a phone charger from the glovebox and a theft of the dummy key in the panniers. They did not open or force any of STella's panniers - (otherwise they may have hit pay dirt), but she is my same old girl from way back.
Been on a few rides since then and apart from lubricating sticky joints from the fingerprinting dust (such as the fuel cap mechanism etc), she is back.
Don't tell her I have my eye on the new Gold Wing though
Cheers, Diesel
