I have one and LOVE it.
i have this seat with back rest. it seems to set you in the same position as the stock seat but is way more comfortable and the seat has a much much better back rest built into it even without the removeable back rest. i though the removeable back rest would hardly be used except for long trips but after riding with it a bit i have found it sucks to be without it. i love the seat so far but it is early in the year and i just got mine end of ride season last year. so far i have 400 miles ride time this year but no long rides. just short 50 - 100 mile runs. but so far so good. i think just about any seat will be better than the stock seat.Is it the same height and distance from the handle bars as the stock seat? I like my riding position but get tired of the numb butt.
