Because the engine isn't designed for topend power.
Similar to the Bandit 1200 and GSXR1100 - same engine but totally different output.

I have a '07 919. I don't know why exactly it redlines at 9500 but I support bladeracer's opinion. The low redline makes it VERY torquey. My buddy has a '07 GSXR 750 and when he rode my 919, all I heard was "holy ****,this bike has torque".I rode his Gixxer and unless you hit 6000 RPM you don't feel a thing. Anyway it's a nice choice of a bike!!! Thumbs up!
P.S. Currently looking into getting a steering damper for it,so it makes me more comfortable in the turns.

As stated, the engine has been re-worked to make power in the mid-range.

After ~9,000 RPM, it starts making less power. Up to that point it makes better power than when configured as the 900RR engine.

The 919 is a great bike for the street. Lotsa fun!

That doesn't sound right to me.
Do you have dyno charts that show this extra power?

No, I sure don't. Never did it myself, and charts of the two bikes on the same dyno from the same day I bet just don't exist.

This is info I have from various forums on the 'net.

It does make sense, though. Smaller intakes (36mm vs. 38mm), re-timed intake & exhaust, all intended to make the 919's engine more suitable for street use (read: lower RPM). As I recall the torque numbers for the 919 are better than the 900RR in the RPM range more often used on the street. The 900RR has a higher redline and better numbers up top.

ETA:
Re-reading my earlier post I see I worded things differently than my intended meaning.
9,000 RPM is near redline on the 919, and right in the power band of the 900RR.
The better power I refer to is around the 5,000 RPM range, not 9,000.

You wouldn't need the bikes to be run on the same dyno on the same day as we aren't interested in outright power numbers. We merely need to see the shape of the curve. Your suggestion of stronger midrange would show an obvious convex curve. Sportrider have the 919 dyno but nothing before 2000 unfortunately. I'd be surprised if it looks much different though.
