Arnob's Cbr250R Detailed Long Term Review

Well speedo errors I agree, but how much do you think it'll be?? At least not in the region of 10 kph. So even deducting all the speed suspicion and doubts- you think it can come to 9 seconds true...good enough isn't it?
Here's a phone GPS snapshot (Blackberry using internal satellite receiver and running on GPSpeedometer s'ware) when my CBR was doing 141 kph:

The military uses different frequencies so they can continue to operate even after shutting the civilian signal. Their satellites.

As for speedometer accuracy, it varies even on the same model. I've heard from people about how accurate the ZMR and P220 speedometers are/were, but others have reported closer to usual errors also. My ZMA (not ZMR) seemed to have a pretty accurate speedometer, it matched the tachometer and predicted speed at RPM precisely but even tachometers have some error.
Bottomline - use multiple sources of measurement , and if it confuses you, take the minimum as most reliable !
I still think the laser speed measurement units were the best , GPS units are a cheap and convenient compromise.
