How do you know that google wasn't telling fibs???
Get on the motorway & do a definitely known distance ie services 5 or 10 miles & compare the results.
All speedos have inaccuracy to a degree but have you tried following a mate in their car, ask them to go a steady 50 mph & compare what your speedo says.
Could eliminate a couple of things.
Easiest way to go fast........don't buy a blue bike
