One of my buddies bought a newer Polaris Predator 500 today and called me to tell me he was coming over to rape the Raptor. My Raptor is bone stock. His predator has slip on big gun exhaust,carb jetting,K&N, and extended swingarm. He also told me the previous owner said it would do 90 to 100. I was under the impression with all of these parts it could get ugly for the raptor. Boy was I wrong!! We raced several times and from each gear as well. Everytime same thing. I pulled on him pretty good. We also made a top speed run in fifth and since my bike does 75 (with my gps ) I even pulled on top so we figured he was doing around 70. It was a really nice bike but just not enough for the raptor. Thought id share.
