Well i purchased a mustang solo and pillion from another forum member. I put them on my bike today and went for a ride.. It deff moves you back about a inch or more, but the comfort is amazing compared to the stock seat. Quality is top notch, i see why people have such good reviews about these seats.
I am not a big guy, 5'6 and a athletic 165, so i dont have much cushion on my butt.. so the stock seat would beat me up after only a hour or so.. i didnt get any discomfort at all with this seat. But it will take some getting used to for how wide it is.
Ill up some pics later.

 

Congrats! I have the Mustang Wide double saddle (not the two separate ones like you) and I LOVE it. It has completely changed the comfort of the ride for the better - especially for the passenger.

Looking forward to pictures...

 

I love the one on my dyna, Its the most comfortable thing I have around to sit on

 

Glad you like them Dog.
