The piston and rings are broken in within the first couple minutes of starting it. The manufacturer recommends that way of break in to be safe and cover themselves.

Take it kind of easy for the first 5 minutes, then ride it progressively harder until the end of the first half hour. By that time, you should be running it at around 70-80% of its capability. Continue that for the remainder of the first hour, change the oil and filter, and declare it broken in.
