RE: GPS versus Odometer
Here's an interesting site: http://www.speedohealer.com/eng/faq.htm
FAQ #16 says:
"
16. What is the "Speedo-to-Odo error ratio"?
There is one speed signal which drives both the speedometer and the odometer.
However, the manufacturers make the display units such a way that the speedometers usually read high, while the odometers are quite accurate on stock vehicles.
Speedo to odo error ratio is the quotient of the indicated speed, and the speed which drives the odometer internally.
This error ratio is fixed in the dashboard logic, i.e. it's bike model specific and will be constant no matter what you change on your bike.
The speedo to odo error ratio is almost the same as the initial (factory) speedo error, considering that the odometers are usually accurate on stock vehicles.

RE: GPS versus Odometer
It's a well known fact among the techno geeks that a GPS is near perfect as long as you have a clear view of the sky. Problem is that the Po-Po may not have his radar as well calibrated. The local dyno guy in town says that all speedo's that he has checked have been off, but the metrics are way worse than the Harleys.
