Rake and Trail would likely be different and potentially the rear swing arm without affecting the main frame.

 

Same frame, yes, but a Fatbob is a Dyna that came out in 2007. It has external shocks mounted on each side. The frame pics you posted are not from a Dyna, unless it all changed for 2018.

 

I mean, ya know what we're talking about here, right?

It's all changed for 2018.

 

all changed for 2018.

 

there's a difference in those frames, well it looks that way. look under the seat and at the rear under the exhaust. may just be the dimensions of the two pictures. softail seems longer

 

Now I know.
Sad.

 

We'll know more tomorrow, but I think the frame/swingarms will be the same across the models. When the Parts list for the 2018 Softails was active, I saw 3 frames, but I think the only difference was paint: Primer, Black, Denim Black. I bet any difference you perceive in those pictures is photo angle, tree angle, and swingarm preload.


We'll know more tomorrow, but denial isn't going to do anyone any good...

 

I think the frames are the same. The rake is longer on the Fatboy.

 

Disappointed in the direction the Dyna line has taken.

 

There is no Dyna, only ZUUL.
