Dumb question by newb

While I've changed sprockets on my R1s in the past and needed to plug in some sort of speedo healer to correct the speedometer.

Since I'm expecting my ZRX this week and trying to read up on as much as I can, I didn't find any posts on how to do this with the ZRX. Do guys that swap in different sprockets not "need" a speedo healer? Or do they just ignore the error in reading?

Thanks,

No speedo healer needed on a ZRX. The ZRX has a speedo drive on the front rim.

As noted, the speedo for the Rex drives off the front wheel. So sprocket size changes will not effect the reading.


What has not be stated so far in this thread is that the speedo on the Rex is already about 10% optimistic. The "healer" for that is to either tweak the needle location on the speedo (discussed in other threads on the board), or install a digital bicycle speedo (also discussed in many other threads).
