I've got one of these that i tried out awhile back that I'm ready to sell now. It's the +25mm version and in near new condition, ridden for less than a month.
I'm 6ft tall but have a short inseam (30" pant length) and have no issues touching the ground. The benefit is a more relaxed knee angle without dropping the pegs and losing lean angle.
This is much better than the factory comfort seat which was already a step up from the stock seat. I had to go full custom due to what's becoming a long term lower back injury that I'm dealing with.
Asking $500 + shipping in the continental US only (lower 48) and I'll cover any shipping costs that exceed $50. It will ship in it's original packaging. Total cost new was $670 so you'll save quite a bit for a great seat that is 99% new.
Paypal business (I'll eat the fees) or Zelle only, cash if you're local is good too.
