hay Hedly, i have a 06 S1K and went to a lot of trouble to try and find out what the torque setting is and there are a lot of Different opinions out there, 150 seems a hell of a lot on an axle nut shouldnt need that to hold it on i think i went less then 70nm and that felt fine what also got me was you dont have a torque rench out in the field if you have to change a tyre, try this do up the nut as tight as you would normaly and then put the torque rench on it to see what amount you have put on it that will give you a good indication of what you should do the nut up too. this may seem a bit Agricultural but you will feel a hole lot better that stripping the nut tring to set it at a to higher torque setting.hope this helps and i'm sure there will be alot of fellow duc rider on this forum that will have a different way of doing this. stay upright mate.
Vale.
