There is a lot more to "break-in" than just the engine, btw. Modern machining and tolerances have eliminated the long drawn out procedures of the old days, but you still need to give all those parts a little time to get aquainted and start working together. Transmission parts, primary drive parts, drive belts and sprockets, tires, etc., not just the engine.
Initially, the big thing is to avoid high temps. In other words, I wouldn't do the first hundred miles in a parade. Follow the recommendations in the manual, avoid burnouts and WOT, and stay off a dyno unless they plan to do a controlled break-in first (break-in on a dyno can be very effective if done correctly).
BTW, taking it easy isn't the same as using common sense. Folks who tell you not to baby it and just "ride it like you stole it" only have half of it right. You don't have to baby it, just ride normally, don't let it overheat, vary your speeds, and use this time to also let you get used to your new ride.
