Hi, my name's Pete. I ride a 2012 Pro RMK. Love the machine! BUT!! We have a problem Houston. The panels are deadly sharp on the aft edge facing your knee and could seriously cut you open. This happened to me. Believe me I enjoy jumping cornises like everyone, but this happened on a 4' drop. My buddy did the exact same drop right ahead of me and he was fine. Not me. My knee slid off my knee pad and straight into the plastic panel which had opened up 1 inch and it sliced through my riding pants, my nike knee protector and my underarmor straight thru to the bone severing my miniscus in my knee joint. OW! Tearful ride ride 25 km. The doctors at the hospital said that I was very fortunate that the main artery had not been severed. So if you have this sled, please dull the sharp aft edge of the panel so that this doesn't happen to you. If you have heard that this has happened to anyone else, please let me know. I have already contacted my Polaris dealer so that they could inform Polaris of this problem.
