I just bought a new 04 YZ450. I used to ride streetbikes and Quads but I decided to try dirtbike. I am having a hard time controlling this bike's power. So far, I haven't left first gear. I always thought that dirtbiking was as easy as riding the Quads. As for taking the corners with some speed and confidence, I tend to use the front brake more often than the rear. Is this right? How do I place my body position? Do I sit almost as close to the gas tank or away from it? As for the height of the seat, should both feet be able to be planted on the ground?
