Welcome to the forum and congrats on your "new" bike. The Ninja 500's really are a lot of fun!
Speedometer error is common on virtually all motorcycles. For some reason, the manufacturers actually build this error into the speedometers. 5% error isn't uncommon. I guess they think it's some sort of safety feature. Personally, I think it's just plain stupid. And yes, it is annoying.
I wonder if the digital speedometers that are becoming so common now also read high. Has anyone tried to verify their digital speedometer accuracy?
