The newer Supersports have a much smaller standard rear hugger. I owned a 1999 750ss, which had the big old rear hugger. I bought a carbon replacement, but it was nearly was big anyway. I now own a 2002 900ss and the OEM rear hugger is much smaller. A lot of road crap does get flicked up onto the pillion seat though.
Have a search through eBay or similar for the hugger from a 2002 or newer SS perhaps.
I've now fitted this hugger and looks pretty good.
The quality of the carbon is very good and fits really well, the only down side for me I suppose is that although smaller than standard it is still pretty big and I really wanted something quite a bit smaller than the standard hugger.
