Does anyone know where you measure on a bike especially on a ktm to know your height difference from front to back to see how much stagger you have to help figure out steering problems and understand the sag on the rear.Also should the front end be moved in the front clamps to accomodate the front sag or does anyone ever worry about front sag?And I guess I should ask what everyone runs on front and rear on sag?Thanks.Maybe a link that could explain it would even be helpful.
