A lot of the back complaints that are attributed to Sportster seats are
probably more likely caused by the short-wheelbase frame bouncing you
around. Thank God I never had any real back issues on my Sportster. =
Still,
after 200+ miles I was sore when I got off the bike. After riding my =
Dyna
Super Glide 200+ miles, with a stock seat and stock suspension, I have =
none
of the soreness or sense of being cramped that I did on the Sportster.=20

Probably the most important change that I made to the Sportster that =
really
contributed to upper body comfort was the pull back risers. Before
installing them most of my upper body weight was supported through my
shoulders, arms, wrists, and hands on the handlebars. With the stock =
risers
I was positioned too far forward to let my back alone support itself.=20

The new risers put me in a much more vertical position. This took the =
strain
off my back, shoulders, arms, wrists and hands.=20

The new Mustang Classic Touring seat had a low back rest of sorts that =
made
me sit more forward on the bike. That made taking advantage of the new
risers ever more comfortable, not to mention how nice the seat was after =
it
was broken in.=20
