I was looking through the Polaris Escape mag that they send. What's the deal with this?? An FST SwitchBack sled has a turbocharged Liberty 750 that puts out 135-hp??? What is the big difference between sled liberty engines and Sportsman engines? Couldn't you, like, put one of these monsters in a Sportsman? That's just scarry. They even have a 900 Liberty engine for them.
