I wouldnt throw a track on any sled of any recent vintage with less than a .92" lug track, let alone a sled with a mountain moniker. I would use nothing less than 1.25" myself, unless funds were tight, and that was the only way to ride that season.
I was amazed that the venture I have came with a .510 lug track in 97.
that has been fixed on our 97 to a studded .92" track. I have yet to try it out since. that will happen this week.
