No harm done as long as you don't redline. There is no evidence of any harm as long as you don't redline the motor while it is so new. In fact, motocycle engines broken-in but accelerations till redline and even above as long as it wasn't held there for long, show a HP INCREASE over ones broken in traditionally with no change in reliability. I'm talking Japanse bikes here. So don't redline, drive normally, DON'T cruise as a specific speed for too long (probabaly the worst thing) and you have nothing to worry about.
The motors are broken in at the factory but it still needs reasonable care to ensure proper seating and polishing. After break-in, you should accelerate freely for best results. Just remember that keeping it over redline for too long will never be helpful- at any stage.
