Hello everyone!!.
Let me give you some context:
Im planing to convert my dtr125 into supermoto, but i want to keep my original speedo working. As the sm wheels are 17" and the original ones are 21", the speedo obviously will not work, so i figured out maybe the speedometers have the same ratio (kms in the spedo/ revs of the speedo cable) and the one thing it changes is the Speedometer drive, so maybe if i change only that part (the one who engages on the whell and measures its revs) the speedometer will work perfectly. I am planning to mount dtx wheels, as they are the easiest to put in my bike, so maybe the speedometer drive outputs the same revs as the one for the 21" wheels but the one for the dtx is specially designed to work in 17" wheels.
With this said, I couldnt figure out any info about the ratio of the speedo or the speedometer drive of a 2006 Dt125x, so i would apreciate a lot any info related to this. Also, if there is a easiest way to maintain the og speedo working, let me know 😄.
Ride safe!!
