I will be getting a Mustang seat with rest see they do 15 and 17 incher and not sure which to get

 

I have the 17.5" and could not be happier. At first, I thought wow...that's wide, but it looks good. I'm glad I didn't go with the 15.5"

 

Same here. And you may not have noticed, but the vast majority of those who are dissatisfied with their Mustang seat bought the narrower version.

 

does it not make to bike seat heavy,the 1inch pillion pad sounds massive

 

Just to muddy the waters got the 15 and no issues. Pick one try it out and if you like it great if not send it back and try the other. I did that with the 2 up touring seat then went with solo and detachable pillion

 

I have the Super Wide Studded touring seat and love it. Just checked, and it is 17.5" wide.Don't go anywhere without it.

 

Here is a picture of my bike with the 17.5" wide vintage with back rest

I have the 17.5" also. Absolutely, the best seat I've owned.

 

i have one, but feel like the horn is too wide... iam not sure if there is any difference in the 15...iam 6' 6" with a 34 inseam the edge of the horn cuts into my inside of thigh..i added a saddleman gel pad and alaskan sheep cover to try and soften that edge but after 300 -400 miles i have had enough..

 

Mine's 17.5 as well, like it for the long rides.
