You expert owners should look at the paddles on your track. I have a freeride but ride with 2 guys with 2020 experts, both 154. On the left side they noticed that their paddles had a small tear on the backside of the base of each paddle and after looking at what could cause it found that the limiter strap adjuster on the side has a cotter key that was hitting the paddles and causing the tear. My buddies just got word that brp is going to warranty their tracks, and I guess they can change how the cotter key goes in so it wouldn't hit the track anymore.
