Hi, has anyone had to do a speedo recalibration? Do you think it is necessary if i go from a 16' rear to an 18' and 19' front to a 21'? My ride is a 2011 Iron sporty.

Be great to get your feedback.

 

yep, you will need the recalibration..

Hey clement reckon youll have to if you need to know acurately how fast you are going. I swapped out my transmission pulley on my 07 kingy as I didnt like riding around in 5th gear most of the time. I got a recalibater from "dakota digital" that plugs into your gearbox and into your speedo leads. It has a couple of arrows on it so you can adjust the speedo up or down, once you have that right it remembers the setting. Very accurate---cheers Grim
