Here`s an old pic of my bike with minus 30mm Hagon Nitro`s and the fork tubes up about an inch.

Here it is more recently with 1-1/4" fork drop and 1" under Progressive 412s for the HD Sportster,a 150-70/17 Avon Azarro in back,an 18" rim in the front and a " poser" seat.[only good for a tank of gas] Its hard to tell with no scale,but that seat is 27" off the ground when I`m sitting on it.
