Not as fast as I look.
Good post. I was hoping you would talk sag. :thumbup 1.3 inches is getting pretty dang ridiculous, I must admit. :laughingFrom what I could tell, all the Sportsters have 2 or less, the Dynas are around 2 or 3.1, some of the softails actually have 4.x like a normal bike, and then the tourers are like the Dynas with some at 2 and some at 3.1.
After sag your 2 is more like 1.3 or 1.4. Might be ok some of the time but you're going to bottom that out. I saw plenty of complaints.
Not sure what you mean by "the reason for more travel is because of acceleration and angles and shortening of the drive line".
In my experience a suspension doesn't smoothly handle a bump equal to its travel. Also a small amount of travel means an even smaller sag... this probably bites you in dips and hitting multiple bumps.
At neutral sag/angle, a straight line between the transmission sprocket and the rear wheel sprocket will be the shortest distance (Drive line). Under acceleration, the rear tire moves more in relation to the frame and needs more travel. And there is more distance, so the driveline must be able to compensate, too.
