GT250R and GT650R Speedometer Sensor
« on: June 12, 2007, 11:07:02 AM »

Just out of curiosity. I noticed that the GT250R and GT650R uses the same speedometer sensor assembly (Part # 34860HP9201). If this is true and the sensor is not adjustable (to suit the different tire size/ diameter - The GT250 uses 110/70-17 tires whereas the GT650 uses 120/60-17 tires), does this mean that one of the model has false speed indication? Not that there's a lot of difference between using 110 and 120, but just wondering.

i know my 250r is about 6-8km/h out!!! i know this as we have these speed trap sensors that just tell u ur speed (nothing else) and i am alwasy 6-8km/h under what my speedo reads.....  :evil:

so when my speedo says 80 is either actually 72 or 74km/h that i am doing!!!!  its annoying knowing this!!!!   :evil:

Maybe that little wheel size difference is what makes our speedo show more speed than the real one. Although I heard that all Comets had some error reading speed.

Depending on the type of sensor it shouldn't matter about tire size. I have dealt with cars while changing wheel and tire size. But considering it is a cheapy sensor it could very well be off, but only by 1-2 mph between the 650 and 250.

Almost every car/ bike is out by 5-10kmh at 100kmh.  Its usually not a dodgy sensor, that's the way its set from factory.  I can even enable the diagnostic mode on my GTI and see the difference between the actual speed the car measures and what it displays on the speedo... 8kmh at 110kmh.
