2004 GSXR 750 Engine Break In?

There are two schools of thought: those that say to baby the motor for the first 200 miles, and those that say to run it hard for the first 20-50 miles. Both schools of thought claim to have perfect results breaking in a motor their way. Both have one thing in common: they say not to run the bike at a steady RPM and speed for the first 20-50 miles. So my personal guess is that it really doesn't matter which way you do it, as long as you don't idle in traffic or cruise at a steady speed on the interstate. I usually run up a back road to the mountains where the RPM varies greatly, and put about 300 miles on it the first day. My last new bike went 130,000+ miles, so I guess the break in worked.
