    Hello everyone - new on here and just replaced my Z750 with a 2018 Z900. Love it but wish to go up one tooth on the front sprocket - any views ? Also I read on another forum that this can throw the speedo reading out but that sounds wrong to me as I think it reads from the rear wheel ??  TIA

    Speedo will be fine, maybe TC on 2020 and newer, but doubt that if only 1 tooth is difference.
    For 2017-2019 no problem with 16 tooth front.


    Anyone have 16 tooth front sprocket on 2020-2021 z900?
    Im also interested to try, but dont know how it works on 2020.

    A 16T will stretch out your shifting a bit more in 1-2 gear, other than that it's pretty normal- nothing drastic. 
    Speedo won't change, it does go off the rear wheel.
    Easy installation.

    Going up one tooth on the countershaft sprocket makes a big difference, especially in the lower gears. I haven't done it on the Z but have on other less powerful bikes. It calms down the low gear revs making for a more mature experience but the bike will stiff feel powerful with little loss of torque off the line.
    Changing the front is easier than the rear and worth it and you don't have to mess with a longer chain. No removal of the rear wheel.  If you don't like it you can easily change back.

    Hi Andy. Iím just up the road from you (off topic).

    Iíve upped the front sprocket on every bike Iíve owned if I primarily use them on the road. I went up 2 front and down 4 on the rear of my Versys 1000. 1200 rpm less at 69.9mph, 4mpg better economy, fully loaded, and zero impact on enjoyment.

    I had to drop out of 6th uphill accelerating at 50mph but hardly death by misadventure.

    Iíd do it on my Z900 but Iím doing track days next year and have 16& 17 tooth cogs in my toolbox ready to try. Theyíre dirt cheap to experiment with.

    Easier to get o

    May I ask did you try the 16t sprocket and if so how did that work for you? I'm thinking of doing the same.

    Yes - bought and fitted. Transforms the bike, much more stable at high revs in first and second and seems to use its power better in the higher gears. No noticeable loss of acceleration - makes me wonder if Kawasaki just got it wrong slightly with the gearing!!

    Hi guys, new joiner here as I just got my Z900 2017 as a used unit recently.

    Quick question, am planning to change sprocket set to 17t front 40t back, had anybody tried this set up?
    ps: digging around the forum and saw 17/41 gives good result too but my current market lacks of 41t in stock. might considering getting 16/39 too...

    TIA for opinions  :037:
