I have one on my 900 RMK. I love it! the cover on the upper part of the seat is crap but its easily replaced. Other than that I really like the storage and additional height as I am a taller rider!
I have one on my 04 REV and really like it as well. It is 2" higher and narrower than stock. I may have the top (easy to do) reupholstered another 1" higher. Give Mike a call 800-470-2442, he does answer the phone
