Speed sensor - sprocket change

[Punkstig]

Thanks chaps, I asked the question as I believe earlier models ran the speedo off the gearbox output shaft, hence the need for a gizmo to recalibrate.  Happy riding.

Not on the fzs600, its always been a unique digital speedo taken from the front whell, but yes there are quite a few bikes out there that use a sensor on the output shaft which would need an adjuster when changing gearing so can understand you're question!
