The Ricambi seat is hopeless so, I wouldn't bother with it if I were you. I have one for my 800ss race bike and whilst it fits, it extends nowhere near far enough towards the tank so there/s a hug gap between where the seat pad fit and where the tank begins - you end up sitting on the frame rails. Also there is not enough room behind the rider to allow him to tuck in and slide back.
