Not really coming across much on the 570 like I thought there would be. I know some of you guys have them, and I'm curious on how the power is and the acceleration on the 570's. Also if anyone has a top speed reading just for kicks. I'm looking to see what kind of acceleration these things are getting, and if they would be equivalent to say a 400ex in terms of speed. Those are the quads I ride with and I want to be able to hang with them.
