Basically something with the piston rings making microscopic grooves in the cylinder walls.~Cheers~
Edit... Ring choice and cylinder material make a big difference in how hard you have to break them in. The one thing I always keep in mind is a couple hard runs won't hurt a thing but breaking it in super easy for 5,000 miles could potentially cause problems. I'm definately not suggesting going to the drag strip or doing top end runs in the first 50 miles.

It's not excessive wear but what it seems happens is the "peaks" get smoothed down into the "valleys" and there's no longer a place for the walls to hold oil in the hone marks. This was also an assembly where I didn't use much moly and that's one of the ingredients in the Honda "break-in" oil. So one thing to remember, it's good to change the factory fill early, just make sure the oil you buy has a decent moly content. I think we've gone off topic again...
