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?
