Hi Ray, and welcome!
Good choice of colour. They are all 2002 models onwards.
As with most that I've seen, my bike is a biposto, with the white single seat fitted - the biposto rear subframe has pillion footrest mounting lugs. If you get a bp, with the dual grey seat, then there should be no problem with fitting a mono seat.
By the way, bear in mind that smooth doesn't necessarily equal fast. Otherwise golf balls would be smooth. Dimpled ones go further and faster...
