Hi
My strada has a QB carbon single seat as you can see in the pic. Its good quality and fit isnt too bad although the front side panels are not quite level with the tank, buts its not that noticable. They dont supply seat pads however but I bought a seat pad and bum pad from Nattyboy for a very reasonable price. Worth asking if he has any more left.
