Title: Speed sensor - sprocket change
Post by: FazerBob144 on 13 June 2013, 04:15:21 pm

Hi everyone,
I guess you can call me a born again biker as I've just bought a 03 FZS600 after a very long time away! Thinking of changing the sprocket ratio to 17-46 from the std 15-48 to drop the revs for motorway cruising. As the 03 bike uses a front wheel speed sensor can this be a straight swap of the sprockets or do I need a gizmo to recalibrate the speedo?

Sprockets have not got anything to do with the speedo, it's more to do with revolutions of the front wheel.

 :agree
the only thing that will effect the speedo is if you change the size of the front wheel for a smaller of larger one.

changing sprockets just changes the gearing

I thought the standard sprockets were 15F 45R ?

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!
