Re: Speedometer Accuracy

[Robert Silas <robert.silas@xxxxxxxxxxxx>]

Bikes' speedos show always more than actual speed.  My friend's 2000 GS indicates approx. 8 km more, my '94 RS shows approx. 3 km more than speed according to my Garmin 2610 GPS.
The type of tires and their conditions are also a factor.

  The bike in question: 2002 R1150r

  Does anyone know how accurate the speedometers for the R1150r's are? I'm 
  currently trying to figure out if my speedometer is way off or if my GPS 
  units is just so cheap that it's not even close.

  Yesterday while running down the highway my speedometer read 92mph, my GPS 
  read 81.7mph and my girlfriends SUV (following closely) was somewhere 
  around 85mph.

  Just wondering if this is normal or time to take it in to be checked (still 
  under warranty).

  Thanks for any help.
