An overly-optimistic speedometer

Today I had my Rino 110 GPS unit with me and I compared it's speed readout and my motorcycle's speedometer reading. As apparently is the case with most motorcycles, my Gretl's speedometer reads 5mph faster than actual speed!

I was holding her steady at 50mph by the speedometer and the GPS unit was reporting 45.4mph or so.

More testing must be done of course since I was concentrating on the road and not on the gps unit which I had stashed in a small pouch on the handlebar and not readily visible all the time. I'll be getting a mounting bracket for the handlebar so I can safely monitor the GPS info while riding.
