I'm a guy, but I'm pretty small - 5'4, 160 lbs, 28" inseam so I can kind of relate to issues that a lot of women have with bikes / seat height / etc
I ride an 04 GSXR1000
Personally, I think the stock seat is pretty comfortable. I'm so short that I ride with my stomach right against the tank all the time
A lot of the aftermarket seats that I've seen, have a flat place at the back thats supposed to support your butt better, but I find they pull me away from the tank and just stretch me out that much further....
I think the stock seat is great in terms of shape / width and all that. Ever thought of getting the stock seat recovered? You could get harder / softer foam / gel put in. I've seen some seats recovered in fabric that was cool too, that might fix the style issue....
Also, I find that where the footpegs / bars are located are a big part of making the bike comfortable. You might be able to move the pegs around with some aftermarket plates or move the clipons, that might increase your comfort. My personal choices aren't normal, I go for the "full race" - footpegs high and back, clipons low & wider, but.... even though thats not what most people consider to be comfortable, I love it, and it works well for me.
Getting the bike to "fit me" really makes me enjoy the bike more - dont be afraid to experiment, find out what works for you!!!
