My ridding buddy rides a 2000 Yamaha YZ 250. Due to the power issue and the wieght game, he does beat me. When I had stock gearing, after adding the pipe, K&N, and airbox holes, it was a very close race. Now that I went to a 13 tooth front sprocket, he beats me again. Dirt bikes are faster, but NO WAY better in my opinion. Don't get me wrong, I have both a love both. But when it comes down to it, I prefer the Predator.
