If the speed shown in a motorcycle's instrument cluster is off by let's say ~5 km/h relative to the actual speed, can we say that the average fuel consumption it shows is also prone to show wrong values because average fuel consumption is a function of summation of fuel used over a given distance and the source to measure the distance got to be the same for current speed shown as well as measuring the fuel consumption. Right !?

Yes, that's how it works, assuming the fuel consumption is calculated from the same sensor (usually on the transmission output shaft,) and not a separate cable to the front wheel, or other such device.– the_storytellerCommented Oct 8, 2019 at 18:02

The speedo is not supposed to under-read, so the manufacturers will calibrate it half-way between the legal limits so it over-reads. Of course they always want to exaggerate fuel consumption so there is no reason why they should make that accurate. Treat the gauge as a guide.– Weather VaneCommented Oct 8, 2019 at 18:46
