    Gen 2 Torque settings

    Hi All
    Does anyone have the Torque Settings for a 2020 Gen 2. I'm replacing my chain & sprockets & looking for front & rear sprocket nut settings. I like to do my own maintenance where possible so a full list would be extremely helpful.
    Thanks in advance

    That looks like torque specs for Gen 1. Rik is asking for Gen 2…….which I don’t know, but don’t use gen 1.

    Sorry not trying to dismiss this, it's a great tip ONCE you have already torqued something down and and want to mark it,

    BUT this is not a good guide if you're replacing any parts such as sprockets. Differences in dimensions from a OEM to pattern part might be enough that the mark you left is now either way too tight or way too loose. Also, and this bike is a brilliant example, factory torqued bolts are often not done up correctly. One of the most common issues on the Gen 1s is engine mounts are torqued up too high transmitting more vibes to the chassis than they should. Torque specs at the factory for non-nutlocked bolts also need to consider initial embedding and settling.

    Technically any torque critical bolt should be rechecked after a certain amount of time as bolts "settle" after the initial torqueing. This is especially true in the case of brand new bolts and bolted surfaces and is accounted for when assembled in the factory.

    Another nitty gritty, is bolts with loctite or any other locking mechanism applied. Say you mark your sprocket bolts like the guy in the video did, you undo the nut - which lets say has loctite on it -, you do your business, you do the bolt back up to the mark and in the process measure what the torque is. Say you acquired 50Nm.

    Now say your marks have faded and you're doing chain and sprockets again, and you have that 50Nm noted down. Lets say you replace the nuts, with fresh loctite on, or reuse the old nuts with old crusty loctite on, or you install new nuts with no loctite but instead a mechanical locking method on (nyloc nuts or flexloc, the type used on stock XR sprockets) all of these can affect what the actual preload placed on the bolt will be, old crusty loctite might reach 50Nm well before the required bolt tension is reached, a many times reused Nyloc nut might produce way more bolt tension at 50Nm than a brand new one.

    Neither of which is good..

    That video is a good rough guide, and even more so a well calibrated wrist will do you wonders, but the only truly good and reliable method is a calibrated torque wrench and the manufacturer stated bolt specs +-10%


    Here is an incredibly good video that goes into the nitty gritty of how bolts actually work:
