Here's a thought: Most cars have rear-wheel drive. Therefore, in most cars, measuring speed from rotation of the front wheel(s) is more reliable because the front wheels should only be able to spin if the car is in forward motion. In contrast, the rotation of the rear wheels is driven by the engine and need not reflect the actual motion of the car - they ...


The speedometer is placed in the location that performs adequately well and that costs the manufacturer the least amount of money, and therefore generates the most profit. Period.


All of my competition cars have had speedos, some of which didn't work at all. I have never once been in a race and had time to take my eyes off what was happening around me to look at the dials. This is why competition cars tend to equip their dashboards with bright lights which come on when attention is required. The times a speedo is useful is during ...


The front wheel is used in most cases with mechanical speedometers (though there are exceptions) because it's just easier (and probably cheaper) to couple the front wheel to the mechanism. Additionally, a mechanical speedometer uses a cable. The longer it is, the less reliable and accurate it becomes, thus the speedometer takes the speed from the nearest ...


Its not a rule of thumb that the Speedometer is connected to the front wheel. There are many Suzukies and hondas in my country that have the speedometer connected to the rear wheel. As Rory stated, the only reason I guess is due to the convenience factor since the front wheel is closer to the cockpit.


There are pros and cons of each, remember you can easily spin or lock up the rear wheel, and in fact the rear wheel may be far less often at the correct speed. So the decision on this stems from physical connectivity it's much easier to connect from the front wheel to the odometer which is on the handlebars than to route from the rear wheel, up under the ...
