XC 700 SP was a later model, 1998 XC-700 is still a very fast machine. Guys were putting the 98 cylindres on thier 99's because of better porting and compression with the 98's. Both machines are very simular in handling and power. shane
I would have to agree with "gman250" my brother-in-law owns two 1996 ultras and only one is a "SP" and the only difference is the SP has fox shocks all the way around. Dont most specials seem to have something "special" with its suspension or engine?
"SP" goes back to 1989. It stands for Special. The specials were limited production Indy's that included gas shocks and stiffer springs as well has a few other beefed up suspension componenets. It was developed for cross country racing and was developed by Polaris with help from Jack Struthers. It is used today to indicate an upgraded suspension.
