There really isn't one. I just took it easy for the first few hundred miles. VARY YOUR RPMS, and just don't redline it every chance you get and you'll be fine.

 

Here is a direct quote from the manual for an'06 600rr:

"Help assure your motorcycle's future reliability and performance by paying attention to how you ride during the first 300 miles (500 km).

During this period, avoid full throttle statrs and rapid acceleration."

It doesn't get much easier than that, especially when you realize what other vehicle manufacturers (motorcycle and car) require for break in periods.
