A buddy of mine picked up a 04 xc 500 and figured he could beat the crossfire. Went out last night and run them about half a dozen times. The crossfire won everytime but sometimes it was alittle too close for comfort. Depending how i would hook up it would be anywhere between beating him by up to 5 sled lengths, and down to about half a sled length. I have run another buddies 04 Pro-X2 700 many times and the crossfire is neck and neck everytime with it. I guess i cant complain i still was winning, just would like alittle more breathing room, especially going against a 500.
