Just because your un-certified speedometer reads a certain speed does not mean that is the actual speed of the vehicle.
We have done some tests at work with our personal vehicles and factory speedos are not always correct. Usually they read over what you are really going. Sometimes they get it backwards and you get paper.
My car's Speedometer reads about 1 or 2 over what I am going, which I personally enjoy
I don't know what my bike's speedometer is set at. But generally a factory speedometer won't read something crazy like 5 mph over even at highway speed, unless of course you changed tire sizes or are running on some very very bald tires.
