I've got around 75 miles on my F7 snopro. When changing tracks I had the rear suspension removed and noticed that the front limiter straps had been worn half way through. Looking at the track I noticed that it was the part that sticks up inside the rails, and is what the drive cogs catch to drive the track that was rubbing the straps. I don't have many miles on mine, but I'm guessing that if all of the Firecats are like this, the straps would be very weak and ready to break at around 300- 500 miles. This is with very low snow conditions, I'm guessing that they'd last longer with good snow. Let me know if anyone else notices what I am talking about.
