[1100]

I have one and love it 1000 km and still looks like new. I wouldn't put one on an 600 lol Basically ask yourself when the last time you powered out climbing a hill with your sled or the last time u spun out. I dont think you can have to much traction in snow. Every time ive ever gone to a bigger track what ive lost in track speed has been worth it because of the ground speed you gain.
