the difference for your year is the xc had polaris factory shocks which are not rebuildable and the seat and gas tank are one piece the sp's had fox shocks and seat and gas tank are seperate and the seat has pads on the side of it. basically the xc was the cheaper more affordable model and the sp was the more aggesive model
Yea I completely forgot about the differnent seat and tank. XC's came with Indy select front adjustable shocks, and a fox position sensitive. XCSP's I would think came with fox rebuildable front shocks, but I'm not completely positive.
Yea, In 99 there were no powervalved xcsp's, just the 98 XCR440 red rocket as they called them. Powervalves started on the 5 and 600's in 2000, and the 700's and 800's didnt get powervalves until 2002.
So no power-valves then. Good then i can get the cheaper oil. Is there like anything i should check out on it. Or like is there anything they are common for breaking down on. I just wanna know more stuff about it basically.
