I want a duck that hasn't been built yet so far as I know. I'd start with a last generation SS half faired bike. Put in a seriously built air cool, like the Hyper Motard motor, ported and polished and loaded with race goodies. have the fairings all nice Carbon. Somehow replace the big headlight with something more modern, maybe the twin set up of the 1098 or even little projector bulbs like the 999's had. BST carbon wheels, annodized open clutch cover, really small light pipes, something insanely loud.
If not then any 916 era ducati, preferably either a Matrix or one of the ones with the gold wheels.
