If I could have any bike for free it would be a Desmosedici probably, but if it was me spending that kind of money (£40k) I'd get a £24k 1098R and pocket the change instead! Lose 20bhp, gain traction control, still not a Desmosedici though I suppose!
Edit: KTM RC8 above is more real world though, £11k and it has completely adjustable everything, all the riding positions and suspension, ride height etc, so it can be comfortable road going bike or focussed "head down - arse up" track bike! Less power than a 1098, but who cares when it can be ridden for more than 80miles 'till reserve out of a tank without also breaking your back in that time.
