Well, I couldn't get the YFZ's and 450R's in the picture. We are both running the stock tires here. They hooked up the best in this loamy track. Holeshot was 1-2 for Suzuki's in both motos. Suzuki's went 1-2 in first moto and 1-4 in the second. My son, Joe, had a YFZ get tangled up with him and they got stuck together. Had to work hard to get 4th after that.
