Where do you find Harley Davidson frame specs?

there are none published for modern harley frames. the geometry of a motorcycle makes it very difficult to accurately measure the frame with available equipment. if there is a suspected problem the dealer is to replace the frame. however, motorcycle frames have been straightened for years. harley dealers could buy a frame straightening table from harley, complete with fixtures for checking, but no actual linear measurements. with automobiles, accurate dimentions can be had by measureing a number of the same model vehicles and take the average. they will be very close. the same can be done with motorcycles but you need specialized measuring equipment. i have done this. i now have specs for most newer harley frames. the cost to do this was huge but i now can straighten frames to spec. i guard these specs closely and give them to no one.
