Personally I feel that keeping it below 50 mph for 1200 miles then running it flat out is about the worse thing you could do
I just keep the load light and slowly work my way up the rev range
Don't let the motor slog or over rev at any time
Don't hold it at a set speed in any one gear for any length of time
That's the way I do it but, I don't know if newer bikes have a way of recording the engine revs or bike speed that would show up if a claim was made under warranty, others here may know!
If I buy a second hand bike I also run it in for 500 Mile's or so just to be safe
