So technically if the bike is revving higher than thought for the given speed.
Assume in the example below, the speedometer is about 10 % optimistic (reads higher than true ground speed):
Indicated speed: 65 mph; true speed; 60 mph; true rpm; 4,000 rpm.
Indicated speed: 60 mph; true speed; 55 mph; true rpm; 3,600 rpm.
