Nice piece of fielding Hick!
If that Aprilia engine, which is rumoured to rev to 14,000 rpm, is in a similar state of tune to the current 250F engines (these are rated in the early forties at the crank by their manufacturers and run up to 13,500 to 14,000 rpm max) we'd have to be looking at something exceeding 70 hp at the crank, or around 60 at the rear wheel!
Where do I sign?
