I have the KTM tall ergo seat for sale, I have used it fir about a year. Perfect condition, adds about 40mm in height over stock seat height. Fits the 08 690 Duke model for certain (maybe others)? This is the one with the Gel insert, 40mm taller than stock (and narrower in middle.) Its def more comfortable on the buns, but this one is too tall for me personally. If you have knee issues, or are taller (6'+ or have an inseam of 33"+) then this is the seat for you. $125 plus ship.
