What the heck does the BMW repair manual mean by “angle torque?”
Angle torque is used to give a stud or bolt an end-use length or tension. Generally, the stud or bolt is prepared by proper lubrication then torqued to some minor amount (eg. 6 foot pounds) then brought up to finish tightness by pulling the wrench through how ever many degrees stated (eg. 32 degrees). The degrees may be stated in one part, two parts or more to bring the object up to tension as determined by the designing engineer. I hate to say this but as owners (not trained mechanics) this is an area where we need to leave it to the professionals. If the part of your bike in question has already been angle torqued and you or another shop tries to do it again, the object will either break or strip out. If there is any question as to weather angle torquing has be carried out on your motorcycle, ask your dealer. If no one knows, don’t take any chances just refer to my Torque Chart and leave it at that.
