I would advise reading up on the cam chain failures for the K12GT. I sold my 07 before that came up. Tough bike to service and maintain.
Compared to what bikes?
My S2R hasn't moved since its gas tank has swelled and rendered it unusable.
In contrast I have a R1200GS and a 1200 Megamoto, both of which have had less than 50% the expense of owning a Ducati.
Yes, they don't 'look' like sexy bikes on paper, but as MadDuck noted they are incredibly fun when moving. The Mega beats either of my Monsters hands down and is far far far more reliable.
