I came accross a dyno test between a stock 08 zx14 and a stock 08 Busa. Same dyno, same day, same guy running the dyno. Both bikes had very similar miles. The Busa pulled 172hp and the zx did 170hp. Here is my issue. I surf forums a lot and occasionally enter the busa forums and read them raving about how the busa is the "King!" I'm afraid I don't understand their math. That 2 hp makes it the King? Even though the said "King" weighs 26lbs more? I dont think so. Power to weight it is still behind the big ninja. But lets go for all or nothing. It is pretty widely accepted that Kawi has a better ram air system than Suzuki. Sportrider did a ram air test on several bikes proving that it can add significant horsepower through the entire range. The Honda Blackbird went from 115hp to 122hp at peak with air being forced down the intakes. I'm sorry but I think the busa is an overhyped, overmarketed second place to the zx. But let me say that the two are so close that I wouldn't dare to say the zx is the King of the hyperbikes(lets leave the Bavarians out of this), because at this distance the rider makes all the difference.
