wow, that link it cool. it is amazing how unaccurate the speedos are. i wonder why that is. is it that the factory isnt calibrating them perfectly or just the simple fact that its a mechanical thing that makes it off a bit. are digital speedos accurate? lol i do 65mph indicated on my 250 to work everyday and was wondering why it would take me longer on that bike to get to work versus my car or other bike doing the same speed. weird.
