Not sure that's worth $7k? Just me. You could put tracks on a pretty decent WR for that budget, or just put Timbersleds on the bike already in your garage. to me that kinda makes riding a snowmobile or snomobike worse, having to stand up all the time. Maybe I'm just old and grumpy
Here's an alternative in the same vein though, saw these at the OR show in January.
