I have no idea about motorcycle engines but with automobile engines they are in essence broken in before you get them, usually before they are even installed in the vehicle. Most engine manufacturer puts them through a really strenuous test procedures that includes running them at RPM's most car drivers would never see. It is not uncommon for owners manuals to not really have a true break-in procedure anymore as a result.My next door neighbor was a machinist. He was the guy you went to with your Ferrari to have the heads redone. I asked him about the two break-in methods one afternoon...and got a Master's thesis on the effects on the cylinder wear and rings, oil, etc. I'd say 95% went over my head, but even the 5% I picked up, was impressive. He basically said to ride it hard for the first 100 miles or so to get the rings seated properly. After that, there was nothing you could do.
