A thought on seats
Sorry, I know this isn't a string dealing with seats, but I wanted to drop in my two cents about the previous post.
Originally when I started looking at M1100's, I was concerned about sliding forward on the seat, and the inevitable impact. Ouch. I ended up buying a used '09 M1100, and it came with the "low", thinner seat. I don't really need it as I'm 6'1", but it came with it, so I've become accustomed to it, and have never had a problem with the angle. The seat is covered with a pretty grippy material, so I don't have much problem with sliding either. I'm still very happy with it, and plan to continue on with it.
I hope this helps.
