Guys, I've come across an article wrote by someone in USA, who has experience with breaking in 300 engines including Honda, not only bikes, cars but also quad and lawn bikes as well.
I'm not sure how accurate this article is but the way this guy explains seems promising.
Here is the link to the article that suggest to break in the engine the hard way:
Break In Secrets--How To Break In New Motorcycle and Car Engines For More Power
I'm not a big fan of break in period to a a few hundred kilometers and the logic that engine pieces needs to settle down when lubricants are there.
Any suggestions ? Or remarks on this ?
