Speedo Error

No, not the Baywatch type.

Typically, when we do riding assessments, we do a quick check of the speedo on the rider's bike. This has served to confirm, as if I needed it, that speedos are awfully inaccurate on a lot of bikes.

Notably, they all seem to read at least a few km faster than the actual speed being travelled. Unfortunately, this causes people trying to stick to the limit to actually ride slower than they are allowed to.

An example of a bike I had some years back was a Gilera Runner. It was a 2 stroke, 180cc scooter, and it went like a cut cat. Trouble was, when I was doing an actual 50 kmh, my speedo was reading 70. Bloody Italians apparently like to think they are going fast all the time.

It also means that if a cop wrote you a ticket for 71 in a 50, (based on a calibrated radar or laser), it is likely that your speedo was reading well over that. Speedo error virtually always makes you go slower, not faster.

In my previous occupation I had the chance to check against a calibrated standard.

Now that we all have either GPS or an app based on GPS on our smartphone, how are your speedos looking? The new knowledge actually makes us go faster.

Just interested in your experiences.
