I can't remember which magazine, either Cycle World or Motorcyclist two issues ago had an article about how to treat your new bike. Many subjects were covered, but one was break-in. They interviewed factory technicians who were responsible for properly preparing bikes for motojouranlist review, including proper breakin. It was the holy grail of comments, as the guys said basically what mototune dude said. Not to that detail, but just that there are no real RPM limitations, more in the method you ride. If you have a copy, take a look as I can't remember the details. FYI, my last two bikes ZX-10R and M109R I've broke in loosely based on the mototune method. I'm in no hurry to hold it WFO so I take my time, but I do ride the bike and sample all it's power and torque during break in, I don't hold it at redline through the gears though. I've never experienced any problems.
