I'd agree with Maxwell on the whole - take it easy (but don't labour the engine) for the first 500-600 miles, then progressively build up to holding higher revs for longer, but all the time keep the engine under load, both acceleration and deceleration.

There is another school of thought that a modern engine actually beds in in the first twenty to one hundred miles (after all, a race bike isn't run in for 500 miles is it?!), and with modern engineering tolerances, all you are really doing is seating the piston rings, plus clearing any crud (such as excess gasket sealant used to seal the cases during assembly) from the oil ways... Certainly off-road [race] bike riders tend to drop the oil after a hundred miles, and call it good...

There are a million different answers to this question, and the simplest is to follow the instructions in your handbook, that way, should you ever have a warranty problem somewhere down the line, you can hand-on-heart say you ran it in as per the manufacturer's instructions?

But personally, I wouldn't nail it for the first five hundred miles, just tend to use lower gears and keep the engine under load in the mid range, both accelerating a decelerating... change the oil, then progressively give it more and more revs up to 1000 miles when you ought to be able to run it at maximum for as long as you like...
