Believe me, I understand the desire to get a bike like this on the road for its first miles! Take an extra few days or an extra weekend or two and get it all done, that is my feeling.
With that said, if you're going to change fluid within 500 miles, may as well do it now... The fluid may have made gunk in the calipers front/rear, the clutch slave cylinder, and I can't see the master cylinders getting away unscathed either.
How's the grease in the wheel bearings?
The bike is liquid-cooled, has the antifreeze held up sitting in there and the hoses are all good? It still is a closed system where antifreeze is keeping things from corroding and doing its thing. Those hoses are like the tires, the rubber isn't getting any newer and it would suck to have one fail.
Overall take a look at the service manual, what does Honda recommend for inspection and replacement intervals? Anything that should have been replaced on a time basis alone should be gone through.
