with about $100K in upgrades, you can build yourself a WSBK replica - the parts are supposed to be available to the public according to the rules.
getting the power up there isn't the main expense. it's the weight loss that WSBK bikes go through - over 100lbs lighter than stock.
and the Suter-BMW was hurting on power this year compared to the Aprilia-powered CRT bikes. The street RSV4 is slower and less powerful than the BMW, but in race tune, it's cranking out lots of power. My best guess is that the 20hp deficit of the street bike is because Aprilia has to warranty those engines, and if they sold them in a 200hp tune, those engines wouldn't last very long.
