Changing sprocket size/teeth for Fxs or Srf
« on: July 30, 2022, 03:04:16 PM »
Hello !

Did anyone change his zero fxs's sprocket size ? If so, does it affect speedometer snd odometer, or do they still indicate the correct numbers ?

Same questio for srf - any experience ?

The speed is taken from the motor RPM and not the wheel speed sensors, so changing the gearing will affect the speedo and odo. Not sure on the SR/F but I would imagine it's the same. When fitting the chain conversion kit the dealer has to plug the bike in the correct the speedo as the gearing is different than the stock belt and pulleys.
