Sorry dude but I don't think it goes at all, the lines are curved not angular and it looks more like a soft saggy molten piece of plastic rather than the sharp cut lines of a klingon war bike!
That is the replicast bellypan used for the SDR Battle 2008 series.
You can buy them direct from Replicast - and they do fit - I know coz I fitted one, but you need to make a cut out for the side stand - as the race bikes have the side stand removed.
