Lets just put it this way:without the SX700,and xtc600 yamaha wouldnt have had a snocross campaign in which in 97 took home some serious gold and brought excitement to owning one of thease sleds,i wish they could bring that excitement back to the snocross track with a 2 stroke clean burning sled to knock the rest of the snowmobile world in x cross on their asses.bumblebees,cats and some other lame brand at the time were no match for the open class sx with titus and vincent in front of the bars,so if you have your doubt, then goin and pout,and by a bee or a kitty and whatever that other sleds name is called LOL
