I have a suzi low touring seat
I bought my 2005 1000 used and it came with stock and touring seats. The lower touring seat does drop the seat height - feels like about an inch? For me it is the difference between tiptoes and (barely) flatfooting it at stops. The lower seat feels a bit narrower than the stock seat, and the foam feels more dense. I've only ridden a little with the stock seat - but the foam is SO soft that it kind of "bunches up" around my butt. Also the contour of the lower seat doesn't seem to give as much fore-aft positioning options - I only seem to fit in one place on the seat.
One thing I don't like about the lower seat is the contour just in front of the step. I think it feels like it needs just a bit more foam carved out, as it feels like the curve forms a high spot that puts some pressure on my tailbone and puts my butt to sleep. The stock seat doesn't seem to do this as badly.
I'm continuing to use the lower seat for the height difference, but am thinking of exploring other options - Sargent or Corbin? The other thing I've considered is trying to make the curve sharper in front of the step by pulling off the cover, removing some of the foam, and stretching the cover back on.
