    New chain and sprockets

    The old chain is starting to get worn out, so i've already ordered a new chain and sprockets for next year. Going for a DID ZVM-X2.

    There is only one thing i am confused about, and that is the torque spec for the rear sprocket nuts on a forged rim. I can't seem to find a definite answer to it as the information on different forums are conflicting.

    One says 110NM and the other say 70NM + an initial 90 degree turn for each nut.

    Also because the nuts have to be replaced with new ones. I was going to order those, but i came across two different codes for (i believe) the same nuts?

    07147105813

    or

    33818522838



    Can someone clarify and have the correct torque spec for the forged rims?

    Thanks in advance.

    For my Gen 2 XR, but with regular rims the rear sprocket nuts are 33818522838 and they are tightened in a star pattern to 110 Nm. I believe they are the same for forged rims
    70Nm plus 90 degrees turn will bring you to approximately 110 Nm so just tighten them do 110 Nm and you should be fine.
    Front sprocket nut is tightened to 125 Nm and I would recommend you to replace the front sprocket nut securing plate too (Part no 23008569916)

    Is the cush-drive spider different for different wheels?  I'd doubt it TBH.

    Probably safer just going for straight torque rather than angular nut displacement - and do it on dry threads.
